したことである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a brush holder for an electric motor and a bracket for holding it, and aims to provide a small, lightweight, and inexpensive electric motor. The feature of the present invention is that the bracket is made of plastic in order to reduce weight and processing man-hours, and the brush holder that holds the brush, which becomes relatively hot during use, is made of heat-resistant metal (e.g., brass). It is.
（１） 以下本発明を図に示す実施例について説明する。(1) The present invention will be described below with reference to embodiments shown in the drawings.

１２に接続されている。A bushing 5 is attached to the small diameter side of the bracket 4, and together with the bushing 3, the armature 6 is rotatably held. Reference numeral 7 denotes a brush holder, which is made of a metal plate such as brass and has an opening 7a shaped like a quadrilateral to house the brush 8.
The other end is press-fitted into the bracket 4 from the inside as a sealed cylindrical part 7b. 9 is a brush steering ring, a coil spring, and commutator 1 of armature 6.
3 is in contact with the brush 8. The pigtail 14 of the brush 8 is brazed to the bottom surface of the cylindrical part 7b of the brush holder 7. When the brush 8 wears out and reaches its usable limit, the pigtail 14 becomes extended and the brush 8 cannot be lowered any further. It disappears. A lead wire 10 is brazed to the top surface of the outer (2) portion of the cylindrical portion 7b of the brush holder 7, and is connected to a power source 12 via a switch 11.

て、アーマチャ６は回転する。When the switch 11 is closed, power is supplied to the commutator 13 through the lead wire IO, brush holder 7, pigtail 14, and brush 8, current flows through the coil of the armature 6, and the armature 6 rotates.
なお、本発明の他の実施例として以下に述べるようなも
のも考えられる。Note that other embodiments of the present invention as described below are also conceivable.
（１）ブラシホルダの形状は開口部７ａを円筒部７ｂと
同形状にしても同様の効果が得られる。この場合ブラシ
８も円柱状となる。(1) The same effect can be obtained even if the brush holder has the same shape as the opening 7a and the cylindrical portion 7b. In this case, the brush 8 also has a cylindrical shape.
（２）ブラシホルダとブラケット４の固定は本例では圧
入としたが、ブラケット４との同時成型でもよ（、この
場合ブラシホルダ７はインサートとなる。(2) Although the brush holder and bracket 4 are fixed by press fitting in this example, they may also be molded simultaneously with the bracket 4 (in this case, the brush holder 7 becomes an insert).
又、別の方法として接着剤による固定法でもよい。Alternatively, a fixing method using an adhesive may be used.
（３１本例ではブラケット４はフレーム１の開口部１ａ
で装着されているが、スルーボルトによるね（３）
じ締結でも同じ効果を期待できる。(31 In this example, the bracket 4 is located at the opening 1a of the frame 1.
However, the same effect can be expected with screw fastening using through bolts (3).
（４）本例ではブラシ８のピッグテール１４ＬＬブーｙ

Although it is brazed to the bottom surface of the cylindrical portion 7b of the brush holder 7, it may also be pulled out through a slit 7c provided in the opening 7a of the brush holder, as shown in FIG. In this case, the end of the pigtail 14 is brazed to the outer periphery of the opening 7a of the brushless duff.
