ABSTRACT:
The object of the present invention relates to reduction of noise during no-load running of a gear device and is to provide a gear shock absorbing mechanism, by which it is possible to damp collision force of tooth against tooth by simplified structure and to reduce gear noise. A driven gear is connected to a driven shaft via a radial gap, and a key connects the driven gear with the driven shaft in rotating direction via a peripheral gap, and an elastic member is compressed in axial direction and is placed between a stop washer connected with the driven shaft and the driven gear.
