Abstract
A slidable constant velocity universal joint holds an elastic member (coil spring) in a stable attitude even if an associated shaft makes an oscillating motion, thereby achieving an improvement in terms of stability in torque transmission. The slidable constant velocity universal joint includes an outer joint member connected to a power transmission member, and an inner joint member connected to an end portion of a shaft, with torque transmission being possible between the outer joint member and the inner joint member while allowing angular displacement and axial displacement. At a forward end of the shaft, there is provided an elastic member for elastically urging the outer joint member toward the power transmission member, and, between the elastic member and the forward end of the shaft, there is interposed a bearing member for guiding the forward end of the shaft while in contact therewith.
