Abstract
An elastic shaft joint comprises a shaft with a pair of outer-diameter side engagement surfaces which are substantially parallel to each other at two positions on the opposite sides of the outer peripheral surface in the radial direction, a rotary member with a pair of restraint plate portions which are substantially parallel to each other, having an opening on a lateral side thereof, and a vibration absorbing member provided between the rotary member and the shaft. The vibration absorbing member is constituted by an elastic member disposed on the inner peripheral surface of a part fixed to the rotary member and a sliding sleeve which is supported by the inner peripheral surface of the elastic member and which inner peripheral surface is in slidable contact with the outer peripheral surface of the shaft.
