CONSTANT VELOCITY UNIVERSAL JOINT AND STEERING DEVICE

摘要

A constant velocity universal joint enabling the improvement of the connection structure of a connection member to an outer member or an inner member and the increase of the yielding thereof. Since the connection member (50) is elastically coupled to an outer ring (10) or the inner member (20), the axial rigidity of both members can be secured, the press-fitting load of the connection member (50) to the outer ring (10) can be reduced, and the trace of press-fitting is not provided to the track grooves (14) and (24) of the outer ring (10) and the inner member (20). For example, when the outer ring (10) is a member formed in a cup shape for fitting the inner member (20) thereto through a retainer (40) and has a through hole (15) on the opposite side of the fitting side thereof with the inner member (20), the fitting part (53a) of the connection member (50) fitted into the through hole (15) of the outer ring (10) is elastically deformed to the outer diameter side and locked to the engagement part (15c) of the outer ring (10).
