Abstract

A plunging-type constant velocity universal joint (2) that comprises an outside joint member (21), an inside joint member (22), eight balls (23), and a retainer (24). The center of curvature O24b of a spherical part (24b) of an outer circumferential surface of the retainer (24) and the center of curvature O24d of a spherical part (24d) of an inner circumferential surface of the retainer (24) are each offset to an axial-direction opposite side by exactly the same distance relative to a joint center O(s). The ratio PCDBALL/DBALL of the pitch circle diameter PCDBALL of the balls (23) to the diameter DBALL of the balls (23) is 3.3–3.6. The ratio WI/DBALL of the axial-direction width WI of the inside joint member (22) to the diameter DBALL of the balls is 1.2–1.55.
