GEARED MOTOR AND POWER WINDOW DEVICE

摘要

A geared motor includes a motor and a reduction drive. The reduction drive includes a gear housing, a speed reduction-output member, and a restriction portion. The gear housing includes a support shaft. The speed reduction-output member includes a reduction gear, an output gear meshed with an input member, and an accommodation recess. The speed reduction-output member is rotationally supported by the support shaft. The restriction portion is configured to restrict movement of the speed reduction-output member relative to the support shaft. The restriction portion is located between an outer circumferential surface of the support shaft and an inner circumferential surface of the accommodation recess. The restriction portion is located in an axial direction of the support shaft at a position that differs from a portion, where the speed reduction-output member abuts in a radial direction against the input member.
