Abstract
A side pressure applying mechanism for a motor may include a rotation shaft of the motor rotatably supported through a support bearing, a side pressure bearing which is loosely fitted to the rotation shaft, an urging member which is abutted with the side pressure bearing to apply a side pressure to the rotation shaft, engaging parts which are formed in a frame and with which both end portions of the urging member are respectively engaged, and a restricting part for restricting movement of the urging member toward the axial direction of the rotation shaft. The restricting part is provided at a position nearer to an abutting position where the urging member is abutted with the side pressure bearing between an engaging position where the urging member is engaged with the engaging part and the abutting position of the urging member with the side pressure bearing.
