Slidable constant speed universal joint

Abstract

There is provided a sliding constant velocity universal joint (3) which allows consistent placement of a coil spring (21) at a predetermined position, visible check into the state of assembly from an external view, and therefore has reduced chances for buckling/deformation of the coil spring (21) and has stable sliding characteristics. In a sliding constant velocity universal joint configured for torque transmission while allowing an angle change and an axial change, an outer joint member (4) incorporates therein an elastic member (21) axially expandable/retractable between a tip of a shaft (1) connected to an inner joint member (5) and the outer joint member (4); the tip of the shaft (1) is provided with a shaft protruding portion (27) for supporting an inner diameter portion of an end portion of the elastic member (21) facing the shaft (1); the elastic member (21) has its end facing the outer-joint-member (4) provided with a receptacle (24) for fitting into an inner diameter portion of the elastic member (21); the outer joint member (4) has its inner surface press-fitted by an end plate (23); and the receptacle (24) is pressed onto the end plate (23) in the inner surface of the outer joint member (4).
