<P>PROBLEM TO BE SOLVED: To provide a slidable constant velocity universal joint capable of further improving joint efficiency by restraining the agglutination and abrasion of mutual metals by reducing frictional resistance not necessarily enhancing the hardness of a contact part by heat treatment. Ž<P>SOLUTION: This slidable constant velocity universal joint has an outside joint member for forming a plurality of straight line-shaped track grooves in the axial direction on a cylindrical inner diameter surface, an inside joint member for forming a plurality of straight line-shaped track grooves in the axial direction on a spherical surface-shaped outer diameter surface, a ball for transmitting torque by being interposed between the track grooves of the outside joint member and the track grooves of the inside joint member, and a cage for holding the ball by being interposed between the inner diameter surface of the outside joint member and the outer diameter surface of the inside joint member. The cage is constituted of a sintered body mainly composed of alumina, zirconia, an aluminum nitride, a silicon nitride and silicon carbide. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
