A thrust bearing device for a motor comprises a housing of the motor, a thrust plate disposed in the housing and in contact with an end of a motor shaft, a spring for energizing the motor shaft through the thrust plate, and the housing is formed with a stepped portion for restricting movement of the thrust plate within a predetermined small range. According to this invention, it is possible to improve the durability and the reliability of the motor.

Thrust bearing device

A nut fixing structure for a resinous case which comprises a nut provided with an antirotative flange and caulking clicks on its respective ends, and a resinous case provided with a nut fitting hole and a flange receiving part. The nut is fixed in the nut fitting hole of the resinous case by bending the caulking clicks outwardly in the state of fitting the nut into the nut fitting hole and engaging the antirotative flange to the flange receiving hole. It is possible to fix the resinous case to the mounting position very firmly.

A small-sized electric motor which comprises a gear case having an end bracket, a holder base, a pair of plate terminals, a sealing member, a terminal container part provided with a projection having a tapered face, and a container cover provided with a projection having as tapered face forming a lower pair with the tapered face of the projection of said terminal container part. This motor has an excellent waterproof property because the end bracket is contact with the plate terminals very closely through the sealing member by the action of the lower pair.

Small-sized electric motor

A small-sized electric motor includes a terminal with a positioner, complementary to a positioner on a brush holder equipped with a brush, for fastening the brush holder to the terminal by deformation of one positioner relative to the other, and a projection with a bendable piece for securing the terminal to a holder base by bending the bendable piece after it is inserted into a terminal hole.
