<p>PURPOSE:To absorb a vibration with the backlash between plural gears in a driving system and thereby make this vibration so as not to be transmitted to a steering shaft, by coupling a driving gear and the steering shaft together via an elastic buffer member and a specified-form coupling member. CONSTITUTION:At a main shaft gear 3, there are provided with four circular holes in size capable of insetting four projections 2a, and these four projections 2a are inserted into an almost central part of each hole. In these four holes of the main shaft gear 3, there are provided with each two of circular cylindrical buffer members 1 so as to hole each projection 2a in between. These buffer members 1 are made up of rubber vulcanized. The main shaft gear 3 is supported by a shaft 8 at a part of the hole formed in the central part via a bearing 7.</p> |
