兼用磁鐵43係僅設置一個，兼作第1驅動部30A之磁鐵與第2驅動部30B之磁鐵。於本實施形態中，第1驅動部30A之磁鐵為兩個，第2驅動部30B之磁鐵為兩個。因此，兼用磁鐵43兼作第1驅動部30A之磁鐵之一部分(一個)與第2驅動部30B之磁鐵之一部分(一個)。 兼用磁鐵43配置於第1線圈33與第2線圈34之間。如圖4所示，將兼用磁鐵43於上下方向夾在配置於下側板彈簧構件60A、60B上表面之絕緣性支持構件44與板彈簧保持構件25之間而保持。另，於兼用磁鐵43與板彈簧構件25之間介隔有上側板彈簧構件50，兼用磁鐵43之上表面利用接著劑等與板彈簧保持構件25及上側板彈簧構件50固定。

第1磁鐵41具有：與第1線圈33對向之第1面41a、及與第1面41a相反側(徑向外側)之第2面41b。第2面41b與側板部22之內側面接觸。第1磁鐵41係如圖3所示於前後方向延伸。第1磁鐵41係大致長方體狀。 第1磁鐵41係其第1線圈33側之磁極即第1面41a之磁極、及與第1線圈33相反側之磁極即第2面41b之磁極互不相同。於圖4中，第1面41a之磁極係S極。第2面41b之磁極係N極。第1磁鐵41之第1線圈33側之磁極(第1面41a之磁極)與兼用磁鐵43之第1線圈33側之磁極(第1面43a之磁極)互為相同(於圖4中為S極)。 第2磁鐵42於左右方向上隔著第2線圈34配置於與兼用磁鐵43相反側。將第2磁鐵42以接著劑等固定於蓋20之側板部22之內側面。第2磁鐵42之上端與上側板彈簧構件50之下表面接觸。且，上側板彈簧構件50與板彈簧保持構件25被夾在第2磁鐵42與蓋20之頂板部21之間。 第2磁鐵42具有：與第2線圈34對向之第1面42a、及與第1面42a相反側(徑向外側)之第2面42b。第2面42b與側板部22之內側面接觸。第2磁鐵42係如圖3所示於前後方向延伸。第2磁鐵42係大致長方體狀。於本實施形態中，第1磁鐵41之形狀與第2磁鐵42之形狀例如互為相同。因此，於本實施形態中，呈長方體狀之第1磁鐵41之長度尺寸(X軸方向之尺寸)、寬度尺寸(Y軸方向之尺寸)、及高度尺寸(Z軸方向之尺寸)各自與第2磁鐵42相同。 第2磁鐵42係其第2線圈34側之磁極即第1面42a之磁極、及與第2線圈34相反側之磁極即第2面42b之磁極互不相同。於圖4中，第1面42a之磁極係N極。第2面42b之磁極係S極。第2磁鐵42之第2線圈34側之磁極(第1面42a之磁極)與兼用磁鐵43之第2線圈34側之磁極(第2面43b之磁極)互為相同(於圖4中係N極)。 與第1線圈33對向之各磁鐵之第1線圈33側之磁極、及與第2線圈34對向之各磁鐵之第2線圈34側之磁極互不相同。 兼用磁鐵43之左右方向之尺寸T3大於第1磁鐵41之左右方向之尺寸T1及第2磁鐵42之左右方向之尺寸T2。第1磁鐵41之尺寸T1與第2磁鐵42之尺寸T2例如互為相同。 另，於本說明書中，各磁鐵彼此之左右方向之尺寸之比較設為通過第1磁鐵、第1線圈、兼用磁鐵、第2線圈及第2磁鐵且於左右方向平行之假想線上之比較。即，即便於各磁鐵之左右方向之尺寸因上下方向或前後方向之位置而不同之情形時，於上述假想線上各磁鐵彼此之左右方向之尺寸關係成立即可。 又，於本說明書中，「各磁鐵彼此之左右方向之尺寸互為相同」係除了各磁鐵彼此之左右方向之尺寸嚴格相同之情形以外，亦包含各磁鐵彼此之左右方向之尺寸相互大致相同之情形。各磁鐵彼此之左右方向之尺寸相互大致相同包含各磁鐵彼此之左右方向之尺寸比為例如0.9以上且1.1以下程度之情形。 第1磁鐵41與第1線圈33之間之左右方向之距離和兼用磁鐵43與第1線圈33之間之左右方向之距離係例如互為相同。第2磁鐵42與第2線圈34之間之左右方向之距離和兼用磁鐵43與第2線圈34之間之左右方向之距離係例如互為相同。又，第1磁鐵41與第1線圈33之間之左右方向之距離和第2磁鐵42與第2線圈34之間之左右方向之距離係例如互為相同。 另，於本說明書中，各磁鐵與各線圈之間之左右方向之距離之比較設為通過第1磁鐵、第1線圈、兼用磁鐵、第2線圈及第2磁鐵且於左右方向平行之假想線上之比較。即，即便於各磁鐵與各線圈之間之左右方向之距離因上下方向或前後方向之位置而不同之情形時，於上述假想線上各磁鐵與各線圈之間之左右方向之距離之關係成立即可。 於兼用磁鐵43中，自N極即第2面43b釋放之磁通於左右方向(於圖4中係向右)通過第2線圈34，並進入第2透鏡保持構件32之徑向內側。進入第2透鏡保持構件32之徑向內側之磁通與來自第2磁鐵42之磁通相斥進入上下方向兩側，通過頂板部21內或基台部70側進入左右方向之第1透鏡保持構件31側(左側)。進入頂板部21內或基台部70側之磁通與來自第1磁鐵41之磁通相斥進入第1透鏡保持構件31之徑向內側，於左右方向(於圖4中係向右)通過第1線圈33並自S極即第1面43a返回至兼用磁鐵43。 另，於本實施形態中，由於以磁性體製之金屬形成蓋20，故自兼用磁鐵43發出之磁通係絕大多數通過頂板部21內而少數通過基台部70側。又，由於於兼用磁鐵43之延伸方向即前後方向之兩端部附近設置有作為內磁軛發揮功能之內壁部23c、23d，故可使來自兼用磁鐵43之磁通有效地作用於第1線圈33。同樣地，藉由內壁部24a、24b作為內磁軛發揮功能，可使來自兼用磁鐵43之磁通有效地作用於第2線圈34。 於第1磁鐵41中，自N極即第2面41b釋放之磁通自側板部22之內側面進入蓋20內。進入蓋20內之磁通於側板部22內進入上下方向兩側，於頂板部21內或基台部70側進入左右方向之第1透鏡保持構件31側(右側)。進入頂板部21內或基台部70側之磁通與來自兼用磁鐵43之磁通相斥進入第1透鏡保持構件31之徑向內側，於左右方向(於圖4中係向左)通過第1線圈33並自S極即第1面41a返回至第1磁鐵41。 另，自第1磁鐵41發出之磁通係絕大多數通過頂板部21內而少數通過基台部70側。又，由於將作為內磁軛發揮功能之內壁部23a、23b設置於蓋20，故可使來自第1磁鐵41之磁通有效地作用於第1線圈33。 於第2磁鐵42中，自N極即第1面42a釋放之磁通於左右方向(於圖4中係向左)通過第2線圈34，並進入第2透鏡保持構件32之徑向內側。進入第2透鏡保持構件32之徑向內側之磁通與來自兼用磁鐵43之磁通相斥進入上下方向兩側，於頂板部21內或基台部70側進入左右方向之第2磁鐵42側(右側)。進入頂板部21內或基台部70側之磁通進入側板部22內並經由側板部22自S極即第2面42b返回至第2磁鐵42。 另，自第2磁鐵42發出之磁通係絕大多數通過頂板部21內而少數通過基台部70側。又，由於將作為內磁軛發揮功能之內壁部24a、24b設置於蓋20故可使來自第2磁鐵42之磁通有效地作用於第2線圈34。 於藉由各磁鐵產生如上所述之磁氣電路之狀態下，若於第1線圈33及第2線圈34電流流通，則基於弗萊明之左手定律，於第1線圈33及第2線圈34產生上下方向之勞侖茲力。藉此，可經由第1線圈33與第2線圈34各者將第1透鏡保持構件31與第2透鏡保持構件32於透鏡體之光軸方向即上下方向驅動。 於具體之本實施形態中，於在第1線圈33流通俯視下順時針方向之電流之情形時，於第1線圈33產生向上之勞侖茲力，故第1透鏡保持構件31向上移動。另一方面，於在第1線圈33流通俯視下逆時針方向之電流之情形時，於第1線圈33產生向下之勞侖茲力，故第1透鏡保持構件31向下移動。 當第1透鏡保持構件31於上下方向移動時，上側板彈簧構件50之彈簧部52c及下側板彈簧構件60A之彈簧部61c、62c彈性變形，將與第1透鏡保持構件31移動之方向相反方向之彈性力施加於第1透鏡保持構件31。第1透鏡保持構件31之移動於第1線圈33所產生之勞侖茲力與彈簧部52c、61c、62c之彈性力之合成力在上下方向上平衡之部位停止。 另，於圖4中，顯示第1透鏡保持構件31於向上側移動之狀態下停止之情形。於該情形時，各保持部52a、52b、61b、62b較各固定部51、61a、62a位於更上側，並向第1透鏡保持構件31施加向下之彈性力。此對於第2透鏡保持構件32亦相同。 於第1線圈33所產生之勞侖茲力可藉由變更供給至第1線圈33之電流之大小而改變。因此，藉由調整供給至第1線圈33之電流之大小，可改變與各彈簧部52c、61c、62c之彈性力之合成力之平衡位置而調整第1透鏡保持構件31之上下方向之位置。向第1線圈33供給電流係藉由與第1金屬板構件72連接之未圖示之外部電源進行。具體而言，電流自外部電源按照第1構件72a、第1部分61、第1線圈33、第2部分62、第2構件72b之順序或其相反順序流通，藉此將電流供給至第1線圈33。 於本實施形態中通過第2線圈34之磁通之方向係與通過第1線圈33之磁通之方向相反方向。因此，為了使第2透鏡保持構件32與第1透鏡保持構件31於上下方向之相同方向移動，以與供給至第1線圈33為相反方向之方式將電流供給至第2線圈34即可。向第2線圈34供給電流係與第1線圈33相同藉由未圖示之外部電源進行。 將電流供給至第1線圈33之外部電源、與將電流供給至第2線圈34之外部電源可為相同之外部電源，亦可為不同之外部電源。 於具備透鏡驅動裝置10之相機中，藉由包含保持於各透鏡保持構件之透鏡體而分別構成之相機單元可拍攝例如立體圖像。又，例如，亦可藉由以各相機單元合成拍攝之各圖像並進行特定之處理，使拍攝之圖像之解析度提高。 根據本實施形態，配置於第1線圈33與第2線圈34之間之兼用磁鐵43兼作第1驅動部30A之磁鐵與第2驅動部30B之磁鐵。因此，可藉由兼用磁鐵43產生第1驅動部30A之第2驅動部30B側之磁氣電路及第2驅動部30B之第1驅動部30A側之磁氣電路兩者。因此，於各驅動部彼此間不會產生磁通之干涉。藉此，即便於將第1驅動部30A與第2驅動部30B靠近而小型化透鏡驅動裝置10之情形時，磁氣電路之設計亦不會變得困難，可容易地進行磁氣電路之設計。又，可將第1驅動部30A與第2驅動部30B配置於所期望之位置。藉由以上，根據本實施形態，可獲得具備複數個透鏡保持構件，可使設計變得容易且小型化之透鏡驅動裝置10。 又，根據本實施形態，隔著第1線圈33於左右方向之相反側設置有第1磁鐵41。第1磁鐵41之第1線圈33側之磁極與兼用磁鐵43之第1線圈33側之磁極互為相同。因此，於藉由第1磁鐵41產生之磁氣電路中通過第1線圈33之磁通之方向、與於藉由兼用磁鐵43產生之磁氣電路中通過第1線圈33之磁通之方向係相互相反方向。又，來自第1磁鐵41之磁通所作用之部分之於第1線圈33流通之電流方向、與來自兼用磁鐵43之磁通所作用之部分之於第1線圈33流通之電流方向係相互相反方向。藉此，於第1線圈33流通電流時，可使於左右方向之兩側產生之勞侖茲力之方向相同。如此，藉由於第1線圈33之左右方向兩側設置第1磁鐵41與兼用磁鐵43，可以2個磁鐵穩定地使第1透鏡保持構件31於光軸方向即上下方向驅動。此對於第2驅動部30B亦相同。 又，根據本實施形態，設置有磁性體製之蓋20，並將第1磁鐵41固定於蓋20之內側面。因此，蓋20相對於第1磁鐵41作為內磁軛發揮功能，可擴大藉由第1磁鐵41產生之磁氣電路之磁通密度。藉此，可增大第1線圈33之於第1磁鐵41側產生之勞侖茲力，可增大藉由第1驅動部30A施加於第1透鏡保持構件31之驅動力。 另一方面，兼用磁鐵43之左右方向之尺寸大於第1磁鐵41之左右方向之尺寸。因此，自兼用磁鐵43釋放出之磁通之量多於自第1磁鐵41釋放出之磁通之量。藉此，可增大藉由兼用磁鐵43產生之磁氣電路之磁通密度，可增大第1線圈33之於兼用磁鐵43側產生之勞侖茲力。因此，可取得於第1線圈33之第1磁鐵41側與於第1線圈33之兼用磁鐵43側產生之勞侖茲力之平衡，可向第1透鏡保持構件31穩定地施加上下方向之驅動力。如以上般，根據本實施形態，可左右方向之平衡良好地增大第1線圈33所產生之勞侖茲力。此對於第2驅動部30B亦相同。 又，根據本實施形態，第1線圈33之捲繞方向與第2線圈34之捲繞方向相同。因此，作為第1線圈33及第2線圈34可分別使用相同種類之線圈。藉此，可減少透鏡驅動裝置10所使用之零件之種類數量，可降低透鏡驅動裝置10之製造成本。又，由於防止了錯取而組裝第1線圈33與第2線圈34，故可提高透鏡驅動裝置10之組裝效率，可提高生產性。 又，第1線圈33與第2線圈34之捲繞次數(圈數)相同，第1透鏡保持構件31之形狀與第2透鏡保持構件32之形狀亦相同。因此，可將固定有線圈之狀態之透鏡保持構件之種類設為一種。 又，根據本實施形態，兼用磁鐵43具有第1面43a與第2面43b，其係於前後方向延伸之形狀。因此，可將兼用磁鐵43設為簡單之形狀，可容易地製造兼用磁鐵43。藉此，可降低透鏡驅動裝置10之製造成本。又，易於將兼用磁鐵43跨及第1線圈33與第2線圈34之間之前後方向全體而配置，且易於增大藉由兼用磁鐵43之磁氣電路於各線圈產生之勞侖茲力。 又，根據本實施形態，將內壁部23a～23d配置於第1透鏡保持構件31之突出部35a～35d彼此之周向之間。因此，可藉由內壁部23a～23d抑制第1透鏡保持構件31繞第1中心軸J1旋轉。又，由於將內壁部23a～23d配置於第1線圈33與第1透鏡保持構件31之徑向之間，故可使內壁部23a～23d作為第1磁鐵41及兼用磁鐵43之內磁軛發揮功能，且可抑制第1透鏡保持構件31於第1中心軸J1之徑向移動。該等對於第2透鏡保持構件32亦相同。 另，本發明並不限定於上述實施形態，亦可採用其他之構成。對於與上述實施形態相同之構成，有藉由適當標註相同符號而省略說明之情形。 透鏡保持構件亦可設置三個以上。於該情形時可構成為：例如將三個以上之透鏡保持構件於左右方向並排配置，且於透鏡保持構件彼此之左右方向之間各自配置兼用磁鐵。 又，與第1線圈33對向設置之磁鐵及與第2線圈34對向設置之磁鐵亦可分別為三個以上。於該情形時可構成為：三個以上之磁鐵於第1線圈33之周圍及第2線圈34之周圍等間隔地設置。又，於該情形時，於三個以上之磁鐵中第1線圈33側之磁極可設為互為相同。於三個以上之磁鐵中第2線圈34側之磁極可設為互為相同。 又，與第1線圈33對向設置之磁鐵及與第2線圈34對向設置之磁鐵可為一個。於該情形時，兼用磁鐵43兼作第1驅動部30A之磁鐵全部與第2驅動部30B之磁鐵全部，並僅以藉由兼用磁鐵43產生之勞侖茲力將第1透鏡保持構件31及第2透鏡保持構件32於上下方向驅動。又，與第1線圈33對向設置之磁鐵之數量和與第2線圈34對向設置之磁鐵之數量可互不相同。 又，驅動第1透鏡保持構件31之方向及驅動第2透鏡保持構件32之方向無特別限定，可為上下方向以外之方向。例如，第1透鏡保持構件31及第2透鏡保持構件32可於前後方向驅動。於該情形時，各線圈繞與前後方向平行之軸捲繞。又，驅動第1透鏡保持構件31之方向、與驅動第2透鏡保持構件32之方向可互不相同。 又，兼用磁鐵43可沿著前後方向分割為複數個。於該情形時，分割之兼用磁鐵43中之於前後方向相鄰之磁鐵可相互接觸，亦可相互分開。又，兼用磁鐵43可沿著左右方向黏合複數個磁鐵而構成。兼用磁鐵43之形狀無特別限定，可為左右方向之尺寸相對較小之板狀。該等對於第1磁鐵41及第2磁鐵42亦相同。 又，第1磁鐵41之尺寸T1與第2磁鐵42之尺寸T2可互不相同。於該情形時，例如可調整各線圈與各磁鐵之間之距離，亦可調整施加於各透鏡保持構件之勞侖茲力。又，各磁鐵之磁力可互不相同。 又，第1線圈33捲繞之方向與第2線圈34捲繞之方向可為相互相反方向。 ＜第2實施形態＞ 圖6係顯示本實施形態之透鏡驅動裝置110之剖視圖。於圖6所示之透鏡驅動裝置110中蓋120係非磁性體製。蓋120係例如非磁性之金屬製或樹脂製。蓋120之其他構成與第1實施形態之蓋20之構成相同。 於透鏡驅動裝置110中兼用磁鐵143之左右方向之尺寸T4與第1磁鐵41之左右方向之尺寸T1及第2磁鐵42之左右方向之尺寸T2及相同。又，兼用磁鐵143之其他尺寸亦與第1磁鐵41及第2磁鐵42相同。關於磁力，兼用磁鐵143亦以與第1磁鐵41及第2磁鐵42相同之方式磁化。兼用磁鐵143之其他構成與第1實施形態之兼用磁鐵43之構成相同。透鏡驅動裝置110之其他構成與第1實施形態之透鏡驅動裝置10之構成相同。 根據本實施形態，由於蓋120係非磁性體製，故蓋120不作為磁軛發揮功能。因此，藉由第1磁鐵41產生之磁氣電路之磁通密度不會因蓋120而變大。藉此，藉由將第1磁鐵41之尺寸T1與兼用磁鐵143之尺寸T4設為相同，可容易地取得第1線圈33之左右方向兩側產生之勞侖茲力之平衡。具體而言，若將第1磁鐵41與第1線圈33之左右方向之距離、和兼用磁鐵43與第1線圈33之左右方向之距離設為相同，則可使第1線圈33之左右方向兩側產生之勞侖茲力相同。此對於第2線圈34亦相同。 又，由於第1磁鐵41之尺寸T1、第2磁鐵42之尺寸T2、及兼用磁鐵143之尺寸T4相同，故可使用相同種類之磁鐵作為各磁鐵。藉此，可減少透鏡驅動裝置110之零件之種類數量，可降低透鏡驅動裝置110之製造成本。又，由於防止了錯取而組裝第1磁鐵41、第2磁鐵41及兼用磁鐵43，故可提高透鏡驅動裝置110之組裝效率，可提高生產性。且可容易地管理各磁鐵。 另，上述說明之各構成於不相互矛盾之範圍內可適當組合。Hereinafter, a lens driving device according to an embodiment of the present invention will be described with reference to the drawings.

Further, since the inner wall portions 23c and 23d functioning as the inner yoke are provided in the vicinity of both end portions in the front-rear direction in the extending direction of the dual-purpose magnet 43, the magnetic flux from the combined magnet 43 can be effectively applied to the first one. Coil 33. Similarly, the inner wall portions 24a and 24b function as the inner yoke, and the magnetic flux from the combined magnet 43 can be effectively applied to the second coil 34. In the first magnet 41, the magnetic flux released from the N-pole, that is, the second surface 41b, enters the inside of the cover 20 from the inner side surface of the side plate portion 22. The magnetic flux that has entered the cover 20 enters both sides in the vertical direction in the side plate portion 22, and enters the first lens holding member 31 side (right side) in the left-right direction in the top plate portion 21 or the base portion 70 side. The magnetic flux that has entered the inside of the top plate portion 21 or the base portion 70 side repels the magnetic flux from the combined magnet 43 and enters the radially inner side of the first lens holding member 31, and passes through the left and right directions (to the left in FIG. 4). The coil 33 is returned to the first magnet 41 from the first surface 41a which is the S pole. Further, most of the magnetic flux emitted from the first magnet 41 passes through the inside of the top plate portion 21 and passes through the base portion 70 side. Further, since the inner wall portions 23a and 23b functioning as the inner yoke are provided on the lid 20, the magnetic flux from the first magnet 41 can be effectively applied to the first coil 33. In the second magnet 42, the magnetic flux released from the first surface 42a which is the N pole passes through the second coil 34 in the left-right direction (to the left in FIG. 4), and enters the radially inner side of the second lens holding member 32. The magnetic flux that has entered the radially inner side of the second lens holding member 32 and the magnetic flux from the combined magnet 43 repel each other in the vertical direction, and enter the second magnet 42 side in the left-right direction in the top plate portion 21 or the base portion 70 side. (Right). The magnetic flux that has entered the inside of the top plate portion 21 or the base portion 70 enters the side plate portion 22 and returns to the second magnet 42 from the second surface 42b which is the S pole via the side plate portion 22. Further, most of the magnetic flux emitted from the second magnet 42 passes through the inside of the top plate portion 21 and passes through the base portion 70 side. Moreover, since the inner wall portions 24a and 24b functioning as the inner yoke are provided on the cover 20, the magnetic flux from the second magnet 42 can be effectively applied to the second coil 34. In the state where the magnetic circuit as described above is generated by each of the magnets, when the first coil 33 and the second coil 34 are galvanically flowed, the first coil 33 and the second coil 34 are generated based on Fleming's left-hand law. Lorentz force in the up and down direction. By the first coil 33 and the second coil 34, the first lens holding member 31 and the second lens holding member 32 can be driven in the optical axis direction of the lens body, that is, in the vertical direction. In the present embodiment, when the first coil 33 flows in a clockwise direction in a plan view, an upward Lorentz force is generated in the first coil 33, so that the first lens holding member 31 moves upward. On the other hand, when the first coil 33 flows in a counterclockwise direction in a plan view, a downward Lorentz force is generated in the first coil 33, so that the first lens holding member 31 moves downward. When the first lens holding member 31 moves in the vertical direction, the spring portion 52c of the upper leaf spring member 50 and the spring portions 61c and 62c of the lower leaf spring member 60A are elastically deformed, and the direction opposite to the direction in which the first lens holding member 31 moves is reversed. The elastic force is applied to the first lens holding member 31. The first lens holding member 31 is stopped at a portion where the Lorentz force generated by the first coil 33 and the elastic force of the spring portions 52c, 61c, and 62c are balanced in the vertical direction. In addition, in FIG. 4, the case where the 1st lens holding member 31 is stopped in the state which moved to an upper side is shown. In this case, each of the holding portions 52a, 52b, 61b, and 62b is located above the fixed portions 51, 61a, and 62a, and applies a downward elastic force to the first lens holding member 31. This is also the same for the second lens holding member 32. The Lorentz force generated in the first coil 33 can be changed by changing the magnitude of the current supplied to the first coil 33. Therefore, by adjusting the magnitude of the current supplied to the first coil 33, the position of the first lens holding member 31 in the vertical direction can be adjusted by changing the balance position of the combined forces of the elastic forces of the spring portions 52c, 61c, and 62c. The supply of current to the first coil 33 is performed by an external power source (not shown) connected to the first metal plate member 72. Specifically, the current flows from the external power source in the order of the first member 72a, the first portion 61, the first coil 33, the second portion 62, and the second member 72b, or vice versa, thereby supplying a current to the first coil. 33. In the present embodiment, the direction of the magnetic flux passing through the second coil 34 is opposite to the direction of the magnetic flux passing through the first coil 33. Therefore, in order to move the second lens holding member 32 and the first lens holding member 31 in the same direction in the vertical direction, current may be supplied to the second coil 34 so as to be opposite to the supply to the first coil 33. The current supplied to the second coil 34 is the same as that of the first coil 33 by an external power source (not shown). The external power source that supplies the current to the first coil 33 and the external power source that supplies the current to the second coil 34 may be the same external power source, or may be a different external power source. In the camera including the lens driving device 10, for example, a stereoscopic image can be captured by a camera unit each including a lens body held by each lens holding member. Further, for example, it is also possible to improve the resolution of the captured image by combining the captured images with the respective camera units and performing specific processing. According to the present embodiment, the dual-purpose magnet 43 disposed between the first coil 33 and the second coil 34 also serves as the magnet of the first drive unit 30A and the magnet of the second drive unit 30B. Therefore, both the magnetic circuit on the second drive unit 30B side of the first drive unit 30A and the magnetic circuit on the first drive unit 30A side of the second drive unit 30B can be generated by the dual-purpose magnet 43. Therefore, interference of magnetic flux does not occur between the respective drive portions. Therefore, even when the first driving unit 30A and the second driving unit 30B are brought close to each other and the lens driving device 10 is miniaturized, the design of the magnetic circuit can be made difficult, and the design of the magnetic circuit can be easily performed. . Further, the first drive unit 30A and the second drive unit 30B can be disposed at desired positions. As described above, according to the present embodiment, it is possible to obtain the lens driving device 10 including a plurality of lens holding members, which can be easily designed and reduced in size. Further, according to the present embodiment, the first magnet 41 is provided on the opposite side of the left-right direction via the first coil 33. The magnetic pole on the first coil 33 side of the first magnet 41 and the magnetic pole on the first coil 33 side of the dual magnet 43 are identical to each other. Therefore, the direction of the magnetic flux passing through the first coil 33 in the magnetic circuit generated by the first magnet 41 and the direction of the magnetic flux passing through the first coil 33 in the magnetic circuit generated by the combined magnet 43 are used. Opposite directions. Further, the direction of the current flowing from the magnetic flux of the first magnet 41 to the first coil 33 and the direction of the current flowing from the magnetic flux of the combined magnet 43 to the first coil 33 are opposite to each other. Thereby, when the current flows through the first coil 33, the direction of the Lorentz force generated on both sides in the left-right direction can be made the same. By providing the first magnet 41 and the dual magnet 43 on both sides in the left-right direction of the first coil 33, the two lenses can stably drive the first lens holding member 31 in the optical axis direction, that is, in the vertical direction. This is also the same for the second drive unit 30B. Further, according to the present embodiment, the cover 20 of the magnetic system is provided, and the first magnet 41 is fixed to the inner side surface of the cover 20. Therefore, the cover 20 functions as an inner yoke with respect to the first magnet 41, and the magnetic flux density of the magnetic circuit generated by the first magnet 41 can be increased. Thereby, the Lorentz force generated on the first magnet 41 side of the first coil 33 can be increased, and the driving force applied to the first lens holding member 31 by the first driving unit 30A can be increased. On the other hand, the dimension of the combined magnet 43 in the left-right direction is larger than the dimension of the first magnet 41 in the left-right direction. Therefore, the amount of magnetic flux released from the dual-purpose magnet 43 is larger than the amount of magnetic flux released from the first magnet 41. Thereby, the magnetic flux density of the magnetic circuit generated by the combined magnet 43 can be increased, and the Lorentz force generated by the first coil 33 on the side of the dual magnet 43 can be increased. Therefore, the balance of the Lorentz force generated on the side of the first magnet 41 of the first coil 33 and the side of the dual magnet 33 of the first coil 33 can be stably applied to the first lens holding member 31 in the vertical direction. force. As described above, according to the present embodiment, the Lorentz force generated by the first coil 33 can be increased in a good balance in the left-right direction. This is also the same for the second drive unit 30B. Further, according to the present embodiment, the winding direction of the first coil 33 is the same as the winding direction of the second coil 34. Therefore, the same type of coil can be used as the first coil 33 and the second coil 34, respectively. Thereby, the number of types of parts used in the lens driving device 10 can be reduced, and the manufacturing cost of the lens driving device 10 can be reduced. Moreover, since the first coil 33 and the second coil 34 are assembled by preventing the misalignment, the assembly efficiency of the lens driving device 10 can be improved, and productivity can be improved. In addition, the number of windings (the number of turns) of the first coil 33 and the second coil 34 is the same, and the shape of the first lens holding member 31 is the same as the shape of the second lens holding member 32. Therefore, the type of the lens holding member in a state in which the coil is fixed can be one. Moreover, according to the present embodiment, the combined magnet 43 has the first surface 43a and the second surface 43b, and is formed in a shape extending in the front-rear direction. Therefore, the dual-purpose magnet 43 can be formed into a simple shape, and the dual-purpose magnet 43 can be easily manufactured. Thereby, the manufacturing cost of the lens driving device 10 can be reduced. Moreover, it is easy to arrange the dual-purpose magnet 43 across the entire front-rear direction between the first coil 33 and the second coil 34, and it is easy to increase the Lorentz force generated in each coil by the magnetic circuit of the dual-purpose magnet 43. Further, according to the present embodiment, the inner wall portions 23a to 23d are disposed between the protruding portions 35a to 35d of the first lens holding member 31 in the circumferential direction. Therefore, the first lens holding member 31 can be prevented from rotating about the first central axis J1 by the inner wall portions 23a to 23d. Further, since the inner wall portions 23a to 23d are disposed between the first coil 33 and the first lens holding member 31 in the radial direction, the inner wall portions 23a to 23d can be used as the inner magnets of the first magnet 41 and the dual magnet 43. The yoke functions to suppress the radial movement of the first lens holding member 31 in the radial direction of the first central axis J1. The same applies to the second lens holding member 32. Further, the present invention is not limited to the above embodiment, and other configurations may be employed. The same configurations as those of the above-described embodiment are denoted by the same reference numerals, and the description thereof will be omitted. Three or more lens holding members may be provided. In this case, for example, three or more lens holding members may be arranged side by side in the left-right direction, and a dual-purpose magnet may be disposed between the lens holding members in the left-right direction. Further, the magnets provided to face the first coil 33 and the magnets disposed opposite to the second coil 34 may be three or more. In this case, three or more magnets may be provided at equal intervals around the first coil 33 and around the second coil 34. Further, in this case, the magnetic poles on the side of the first coil 33 among the three or more magnets may be identical to each other. Among the three or more magnets, the magnetic poles on the second coil 34 side may be identical to each other. Further, one magnet that is disposed opposite to the first coil 33 and one magnet that faces the second coil 34 may be one. In this case, the dual-purpose magnets 43 also serve as all of the magnets of the first drive unit 30A and the magnets of the second drive unit 30B, and the first lens holding member 31 and the first lens holder only by the Lorentz force generated by the combined magnet 43. The lens holding member 32 is driven in the vertical direction. Further, the number of magnets disposed opposite to the first coil 33 and the number of magnets disposed opposite to the second coil 34 may be different from each other. Moreover, the direction in which the first lens holding member 31 is driven and the direction in which the second lens holding member 32 is driven are not particularly limited, and may be directions other than the vertical direction. For example, the first lens holding member 31 and the second lens holding member 32 can be driven in the front-rear direction. In this case, the coils are wound around an axis parallel to the front-rear direction. Further, the direction in which the first lens holding member 31 is driven and the direction in which the second lens holding member 32 is driven may be different from each other. Further, the combined magnet 43 can be divided into a plurality of pieces in the front-rear direction. In this case, the magnets adjacent to each other in the front-rear direction of the divided dual-purpose magnets 43 may be in contact with each other or may be separated from each other. Further, the combined magnet 43 can be configured by bonding a plurality of magnets in the left-right direction. The shape of the combined magnet 43 is not particularly limited, and may be a plate shape having a relatively small size in the left-right direction. The same applies to the first magnet 41 and the second magnet 42. Further, the size T1 of the first magnet 41 and the size T2 of the second magnet 42 may be different from each other. In this case, for example, the distance between each coil and each of the magnets can be adjusted, and the Lorentz force applied to each of the lens holding members can be adjusted. Moreover, the magnetic forces of the magnets can be different from each other. Further, the direction in which the first coil 33 is wound and the direction in which the second coil 34 is wound may be opposite to each other. <Second Embodiment> Fig. 6 is a cross-sectional view showing a lens driving device 110 of the present embodiment. In the lens driving device 110 shown in Fig. 6, the cover 120 is a non-magnetic system. The cover 120 is made of, for example, a non-magnetic metal or a resin. The other configuration of the cover 120 is the same as that of the cover 20 of the first embodiment. In the lens driving device 110, the dimension T4 of the magnet 143 in the left-right direction is the same as the dimension T1 of the first magnet 41 in the left-right direction and the dimension T2 of the second magnet 42 in the left-right direction. Further, the other sizes of the combined magnet 143 are also the same as those of the first magnet 41 and the second magnet 42. The combined magnet 143 is also magnetized in the same manner as the first magnet 41 and the second magnet 42 in terms of magnetic force. The other configuration of the dual-purpose magnet 143 is the same as that of the dual-purpose magnet 43 of the first embodiment. The other configuration of the lens driving device 110 is the same as that of the lens driving device 10 of the first embodiment. According to the present embodiment, since the cover 120 is a non-magnetic system, the cover 120 does not function as a yoke. Therefore, the magnetic flux density of the magnetic circuit generated by the first magnet 41 is not increased by the cover 120. By setting the size T1 of the first magnet 41 and the size T4 of the dual-purpose magnet 143 to be the same, the balance of the Lorentz force generated in the left and right directions of the first coil 33 can be easily obtained. Specifically, when the distance between the first magnet 41 and the first coil 33 in the left-right direction and the distance between the dual-purpose magnet 43 and the first coil 33 in the left-right direction are the same, the first coil 33 can be oriented in the left-right direction. The Lorentz force generated on the side is the same. This is also the same for the second coil 34. Further, since the size T1 of the first magnet 41, the size T2 of the second magnet 42, and the size T4 of the dual magnet 143 are the same, the same type of magnet can be used as each magnet. Thereby, the number of types of parts of the lens driving device 110 can be reduced, and the manufacturing cost of the lens driving device 110 can be reduced. Moreover, since the first magnet 41, the second magnet 41, and the dual magnet 43 are assembled by preventing the misalignment, the assembly efficiency of the lens driving device 110 can be improved, and productivity can be improved. And each magnet can be easily managed. Further, the respective configurations described above may be combined as appropriate within a range that does not contradict each other.
