Claims

[Claims for Utility Model Registration] 1. A shaft that mainly transmits rotational motion, a housing into which the shaft is inserted concentrically, an elastic member provided between the shaft and the housing, and a shaft that transmits rotational motion. In an elastic shaft joint comprising a stopper for preventing excessive relative displacement with the housing, the housing has a yoke at one end for holding a spider of the universal joint, and the elastic member has a circular tubular outer member. It has a ring and a cylindrical elastic body fixed to the inside of the outer ring, the shaft is press-fitted into the center of the elastic member, and the stopper is connected to the housing, the elastic member, and the shaft. The pin member is press-fitted into the through-hole portion of the shaft of the formed through-hole, and the clearance between the end of the pin member and the through-hole portion of the housing and the outer ring is such that the entire circumference of the pin member is An elastic shaft joint characterized by being uniform across the length. 2. Utility model registration claim 1, characterized in that the outer ring of the elastic member protrudes from an end of the housing opposite to the end forming the yoke and is press-fitted into the housing. Elastic shaft coupling described in section. 3. Utility model registration claim 1 or 2, characterized in that the elastic member comprises the outer ring, the elastic body, and a cylindrical inner ring coupled to the inside of the elastic body. Elastic shaft coupling as described in Section. 4. An end portion of the pin member facing the housing and the outer ring is a concentric diameter-reduced portion that is thinner than the center portion of the pin member, and the through hole has the same diameter over the entire length of the hole. An elastic shaft joint according to any one of claims 1 to 3 of the utility model registration claims.
