【考案の詳細な説明】
本考案は組立の容易で小型な可変抵抗器を提供しようと
するものである。[Detailed Description of the Invention] The present invention aims to provide a small variable resistor that is easy to assemble.
可変抵抗器の回転軸は刷子取付板の透孔にもの先端の段
部を挿入し、その後先端部をかしめるかあるいは座金を
はめて固定していた。The rotary shaft of the variable resistor was fixed by inserting the stepped part at the tip into the through hole of the brush mounting plate, and then caulking the tip or fitting it with a washer.
したがってかしめ代あるいは座金の取付場所が必要とな
り可変抵抗器を小型化する障害となっている。Therefore, caulking allowance or a mounting location for the washer is required, which is an obstacle to miniaturizing the variable resistor.
またかしめ作業、座金を取付ける作業に手間を要し、組
立が容易にできないものである。Further, the crimping work and the work of attaching washers require time and effort, and assembly is not easy.
そこで本考案は組立を容易にしかも小型化することがで
きる可変抵抗器を提供しようとするものであり、以下本
考案の実施例について図面を用いて説明する。Therefore, the present invention aims to provide a variable resistor that can be easily assembled and downsized.Examples of the present invention will be described below with reference to the drawings.
第１図、第２図、第３図に示すように、取付板１に抵抗
体２を取付け、この取付板１と軸受３とをシールドケー
ス４とともに係合しておく。As shown in FIGS. 1, 2, and 3, a resistor 2 is attached to a mounting plate 1, and the mounting plate 1 and a bearing 3 are engaged together with a shield case 4.
上記軸受３に挿入される回転軸（中空回転軸）５の先端
部に円周に沿って溝７を形成する。A groove 7 is formed along the circumference at the tip of the rotating shaft (hollow rotating shaft) 5 inserted into the bearing 3.
この回転軸５は筒状をしており、この中央孔に別の回転
軸（中心回転軸）８が挿入される。This rotating shaft 5 has a cylindrical shape, and another rotating shaft (center rotating shaft) 8 is inserted into this central hole.
上記抵抗体２に摺動接触する刷子９を取付けた刷子取付
板１０に透孔１１を設け、この中心孔１１に上記回転軸
５の先端部を圧入し、溝７に刷子取付板１０の透孔１１
の縁部を嵌入する。A through hole 11 is provided in the brush mounting plate 10 to which the brush 9 that is in sliding contact with the resistor 2 is attached, and the tip of the rotating shaft 5 is press-fitted into the center hole 11. Hole 11
Insert the edge of the
この回転軸５の先端部の嵌合は、後述するような切込１
４ａ、１４ｂが設けられているため同回転軸５の先端は
弾性を有し、容易に行なえる。The fitting of the tip of the rotary shaft 5 is performed by making a cut 1 as described later.
4a and 14b, the tip of the rotary shaft 5 has elasticity and can be easily operated.
回転軸５は合成樹脂等の少しやわらかいもので作ってお
けば上記の圧入はさらに容易になる。If the rotating shaft 5 is made of a slightly soft material such as synthetic resin, the press-fitting described above will be easier.
１２は抵抗体１３を取付けた取付板であり、回転軸８用
のものであるが詳細な図面は省略しである。12 is a mounting plate to which a resistor 13 is attached, and is for the rotating shaft 8, but detailed drawings are omitted.
回転軸５の先端部には先端より上記溝７の上記先端より
遠い方の縁部にまで達する切込１４ａ。The tip of the rotating shaft 5 is provided with a notch 14a that reaches the edge of the groove 7 farther from the tip than the tip.
１４ｂが形成されている。14b is formed.
この切込１４ａ、１４ｂは溝７よりも深いものである。The cuts 14a and 14b are deeper than the groove 7.
実施例では中心孔にまで達している。In the embodiment, it reaches the center hole.
刷子取付板１０の透孔１１の内壁には上記切込１４ａ、
１４ｂに嵌合する突片６が設けられている。The inner wall of the through hole 11 of the brush mounting plate 10 has the above-mentioned notch 14a,
A protruding piece 6 that fits into 14b is provided.
この突片６を設ける位置をあらかじめ刷子９との関係を
考慮して設定しておけば、刷子９は抵抗体２の所定の位
置に接触するので都合がよい。It is convenient if the position of the protruding piece 6 is set in advance in consideration of the relationship with the brush 9, since the brush 9 will come into contact with a predetermined position of the resistor 2.
さらに、回転に対しても軸の先端の変形をうけにくい。Furthermore, the tip of the shaft is less susceptible to deformation due to rotation.
以上のように本考案によれば回転軸の先端部に設けた溝
に刷子取付板をはめ込むようにしたので刷子取付板取付
用に特別の金具およびスペースを必要とせず組立が簡単
で可変抵抗器を小型にすることができるものである。As described above, according to the present invention, since the brush mounting plate is fitted into the groove provided at the tip of the rotating shaft, there is no need for special metal fittings or space for mounting the brush mounting plate, and assembly is easy and the variable resistor can be easily assembled. can be made smaller.
