Abstract
A small-sized motor equipped with a worm reducer according to the present invention includes a cavity portion,formed in a gear case,which accommodates a worm,mounted on a motor shaft,and a worm wheel,The cavity portion,receives a front end of the motor shaft,and does not communicate with the exterior thereof. A bearing holder,holding a bearing device is disposed in the cavity portion,such that a metallic-fiber-containing resin spacer or metallic spacer,is disposed between the bearing holder,and the gear case,Thrust adjustment for the motor shaft,is performed through application of thrust to the motor shaft,after the resin spacer is softened through induction heating effected electromagnetically from outside the gear case, or after a gear case protrusion, which is in contact with the metallic spacer, is softened through application of heat transmitted from the metallic spacer heated through induction heating effected electromagnetically from outside the gear case. Thus, the motor shaft can be fixedly positioned accurately with respect to the thrust direction.
