[Operation] In the commutator motor of the present invention, the terminal connecting fitting of the brush device is not only the terminal engaging portion connected to the connecting terminal, but also the spring receiving portion is bent and connected integrally with the engaging portion. Since it is formed, the number of parts of the brush device can be reduced. Therefore, the structure is simplified, and the labor for assembling is reduced, so that the structure can be easily manufactured, and the cost can be reduced. Moreover, since there are few connection points in the electrical connection between the connection terminal and the brush, the reliability of the electrical connection between them can be improved.

Further, since the structure is such that the terminal engaging portion of the terminal connecting fitting and the connecting portion of the connecting terminal are connected in the through hole of the brush holder body, external force is prevented from being applied to these connecting portions, and the connecting terminal is prevented. Also, electrical and mechanical connection of the terminal connection fitting can be maintained. Moreover, after assembly, the terminal engaging portion is elastically deformed to absorb externally applied vibrations and the like, and the connection state between the connection terminal and the terminal connection fitting can be reliably maintained.

Further, the terminal engaging portion of the terminal connecting fitting is elastically deformable, and the connecting terminal is sandwiched between this and the inner wall surface of the through hole to electrically and mechanically connect the terminal connecting fitting and the connecting terminal. Therefore, a slight positioning error at the time of assembly can be absorbed by the elastic deformation of the terminal engaging portion. Moreover,
By providing the inclined portion at the tip of the terminal engaging portion, even if the position of the connection terminal is slightly deviated, it can be smoothly introduced into the through hole by the guide using the inclination of the inclined portion. In addition, since the engaging part bent from the inclined part is hooked on the commutator side hole edge of the through hole,
In the automatic assembly, even though the inclined portion is pushed by the connection terminal, the terminal connection fitting does not come out of the through hole, so that the action of introducing the connection terminal into the through hole and the inner wall surface of the through hole It is prevented that the pinching action of the connection terminal between the two is impaired. Therefore, it is possible to reduce the dimensional accuracy of components such as the connection terminals and the terminal connection fittings, and increase the positioning tolerance of these components.
