第2壁部27は、支持板部24から第2方向Yに離れている。第2壁部27は、一対の第1壁部26における第2方向Yの端部同士を連結している。第2方向Yは、第1方向Xおよび上下方向に直交している。
以下、上下方向を第3方向Zという。
連結部33は、第2ストッパ部32から、第1方向Xおよび第2方向Yに交差する第3方向Zに離れて設けられている。連結部33は、第1ストッパ部31の柱部31bにおける上端部同士を第1方向Xに連結している。柱部31bが、第1ストッパ部31における連結部33との接続部分となっている。
第1ストッパ部31、第2ストッパ部32、および連結部33は、例えばゴム材料等で一体に形成されている。
第1規制部35は、共通軸Oより下方に位置している。第1規制部35は、2つの支持板部24から各別に、第2方向Yに沿う装着孔24aの反対側に突出する一対の第3壁部36と、一対の第3壁部36同士を第1方向Xに連結する第4壁部37と、を備えている。
スナップフィット突起38のうち、架橋壁34から下方に突出した先端部に、第1方向Xに張り出した張出突起38aが形成されている。張出突起38aは、架橋壁34の下面に当接、若しくは近接している。なお、張出突起38aは、スナップフィット突起38の先端部に、第2方向Y等に張り出して形成されてもよい。
したがって、第1規制部35は、第1ストッパ部31および第2ストッパ部32のうちの少なくとも一方に、第2方向Yに当接、若しくは近接し、第1ストッパ部31および第2ストッパ部32のうちの少なくとも一方の、第1取付部材11から第2方向Yに離れる向き(第2方向Yの外側)の移動を規制する。
したがって、弾性ストッパ30を、第1取付部材11に、第3方向Zに締め付けることが可能になり、弾性ストッパ30を第1取付部材11に接着しなくても、例えば車両等への組付け時に、弾性ストッパ30が第1取付部材11に対して位置ずれするのを抑えることができる。
第1ストッパ部31、第2ストッパ部32、および連結部33が、一体に形成されているので、部品点数の増大を防ぐことができる。
したがって、第1ストッパ部31および第2ストッパ部32のうちの少なくとも一方が、第1取付部材11に対して第2方向Yに位置ずれするのを確実に抑制することができる。また、第1規制部35および第2規制部39によって、第1ストッパ部31の柱部31bを第3方向Zに強く引張しても、スナップフィット突起38が、第1ストッパ部31および第2ストッパ部32のうちの少なくとも一方から第3方向Zに抜けるのを抑制することができる。
なお、この第2実施形態においては、第1実施形態における構成要素と同一の部分については同一の符号を付し、その説明を省略し、異なる点についてのみ説明する。
第1規制部35の第3壁部36に、第2方向Yの内側および下方に開口した係止凹部39bが形成されている。係止凹部39bは、第3壁部36を第1方向Xに貫く。係止凹部39bは、第3壁部36の下端部に形成されている。係止凹部39bに、架橋壁34が挿入されている。
係止凹部39bの内面のうち、上端に位置して下方を向く上端面に、架橋壁34の上面が当接、若しくは近接している。これにより、第1規制部35は、第1ストッパ部31を係止し、第1ストッパ部31の上方に向けた移動を規制する。
さらに、第1規制部35の第3壁部36に、係止凹部39bが形成され、係止凹部39bに、架橋壁34が挿入され、係止凹部39bの上端面に、架橋壁34の上面が当接、若しくは近接している。したがって、第1ストッパ部31の柱部31bを、第1規制部35および第2規制部39によって第3方向Zに強く引張した状態を確実に維持することができる。
第1規制部35と、第1ストッパ部31および第2ストッパ部32のうちの少なくとも一方と、に、互いに係合する凹凸部等を設けることにより、第1規制部35が、第1ストッパ部31および第2ストッパ部32のうちの少なくとも一方を係止する構成を採用してもよい。
第1取付部材に、第1ストッパ部および第2ストッパ部のうちの少なくとも一方と、連結部と、を係止し、第1ストッパ部および連結部が、第3方向に互いに接近することを規制する一対の規制部が設けられ、第1ストッパ部における連結部との接続部分が、第3方向に引張されている。したがって、弾性ストッパを、第1取付部材に第3方向に締め付けることが可能になり、弾性ストッパを第1取付部材に接着しなくても、例えば車両等への組付け時に、弾性ストッパが第1取付部材に対して位置ずれするのを抑えることができる。
第1ストッパ部、第2ストッパ部、および連結部が、一体に形成されているので、部品点数の増大を防ぐことができる。
