Abstract
A geared motor assembly has a rotation-transmitting shaft for transferring output rotation of a reducer on the front side of a motor to an output shaft sensor on the rear side of the motor. A front end portion of the rotation-transmitting shaft is securely bonded to a rotation output member of the reducer by an adhesive that exhibits flexibility or elasticity after hardening, and a rear end portion of the rotation-transmitting shaft is rotatably supported by a sensor cover via a bearing in a position adjacent to the output shaft sensor. The rotation-transmitting shaft can be supported in a state free of axial runout by deformation of the adhesive and by the bearing. Consequently, the rotation angle position of the rotation output member can be detected with precision by the output shaft sensor in a position adjacent to the bearing.
