音対策を優先的に行う必要がある。2. Description of the Related Art As a noise source of an electric motor, there are vibration accompanying rotation of a rotor, vibration of a brush generated by sliding of a brush on a rotating commutator, and the like. Especially in small electric motors, the noise caused by brush vibrations accounts for a large percentage of the total noise among these noise sources, and in order to effectively reduce noise in small electric motors, noise countermeasures caused by brush vibrations should be prioritized. There is a need to do.

ムへ伝達することを防止している。Of the noise caused by the brush vibration, the brush vibration is transmitted to the end frame that closes the opening of the housing, and the noise generated by the vibration of the end frame is described in, for example, JP-A-3-970.
The device described in Japanese Patent No. 1 has been proposed. In particular,
A brush holder made of an insulating material such as resin that holds the brush of the electric motor is formed separately from the end frame, and they are connected by fastening means such as bolts through an elastic body such as vibration-proof rubber. , It prevents the vibration of the brush from being transmitted to the end frame.

場合にやはり有効に振動を減衰させることができない。However, in the device described in the above publication, when the tightening torque of the bolt is less than the set value, there is play between the brush holder and the end frame, and the anti-vibration rubber is used. Vibration cannot be damped effectively. On the other hand, if the tightening torque of the bolt is more than the set value, the anti-vibration rubber will bend more than the set value in the assembled state, so it will not be possible to further bend by the maximum amplitude of the brush holder from that state, In this case, too, the vibration cannot be effectively damped.

It is not possible to effectively reduce noise. Further, in the device described in the above publication, since the anti-vibration rubber is required, the number of parts and the number of assembling steps accompanying the increase in the number of parts are increased.

4 is provided on the axis of the brush 9 except that the other conditions are the same and the acceleration of 10 m / s 2 is 0d.
9 shows the relationship between the acceleration and the frequency, which is B. Incidentally, FIG. 8 shows an example in which the protrusion 14 is not provided on the axis of the brush 9. Further, since the brush holder portion 10 and the end frame 4 are integrally molded, it is not necessary to consider the suitability of the assembled state of the both, so that unnecessary vibration of the end frame 4 does not occur. . Therefore, the noise of the electric motor can be reduced by a simple means such as providing the protrusion 14 on the axis of the brush 9. Therefore, while reducing the noise of the electric motor, the number of parts is reduced and the assembling property is improved. Manufacturing cost can be reduced.
