Motorvorrichtung und Getriebemechanismus

摘要

In a transmission mechanism having a disk shaped output plate having a flat surface and an output shaft, the output plate is provided in a center thereof with a linking portion formed by drawing to axially extend from the flat surface. The linking portion has a shaft receiving hole with a plurality of engaging surfaces extending axially for receiving circumferential rotational driving force. The output shaft is provided at an axial end thereof with a shaft inserting portion fitted to the shaft receiving hole so that the output shaft is connected to the output plate so as to rotate together therewith in a state that an axial length of the shaft inserting portion in contact with each of the engaging surfaces is longer than the thickness of the flat surface.
