PROBLEM TO BE SOLVED: To provide a fixed type constant velocity universal joint used for transmitting driving force like a drive shaft and a propeller shaft, without imparting large adverse influence to durability, and restraining looseness in the rotational direction without adding a new part. SOLUTION: This fixed type constant velocity universal joint has an outer ring of axially forming a plurality of track grooves at equal intervals in the circumferential direction on an inner spherical surface, an inner ring of axially forming a plurality of track grooves making a pair of the track grooves of the outer ring at equal intervals in the circumferential direction on an outer spherical surface, a plurality of balls transmitting torque by interposing between both track grooves of the outer ring and the inner ring, and a cage 40 of forming a pocket 41 at equal intervals in the circumferential direction for holding the balls by interposing between the inner spherical surface of the outer ring and the outer spherical surface of the inner ring. The pocket center O<SB>4</SB>of the cage 40 is offset to the anti-opening side of the outer ring from the joint center O. COPYRIGHT: (C)2007,JPO&INPIT
