Geared motor having worm wheel drivingly connected to output shaft

摘要

In a geared motor, a cover plate is fitted to an opening of a housing of a geared motor. The cover plate includes an output shaft hole, a rib and a short cylindrical portion. The output shaft hole penetrates through a center of the cover plate and rotatably receives an output shaft therethrough. The rib is formed along an outer peripheral edge of the cover plate and is radially supported by the housing. The short cylindrical portion is slidably engageable with an outer peripheral surface of the output shaft for radially supporting the output shaft. An inner peripheral surface of a worm wheel is slidably engageable in line contact with a sliding ridge of a disk plate of the output shaft.
