PROBLEM TO BE SOLVED: To provide a sliding-type tripod constant velocity joint, reducing costs and reducing a weight of a retainer by reducing a load of the retainer received from a needle and an outer ring. SOLUTION: An intermediate member 40 is rockably provided around an outer periphery of a corresponding one of tripod shaft portions 22. Shaft-like rolling elements 50 are retained by corresponding retainers 60 so that the shaft-like rolling elements 50 circulates around the corresponding intermediate members 40 and rolls between side surfaces 163 of a corresponding one of raceway grooves 16 of the outer ring 10 and a torque transmitting surface 41 of a corresponding one of the intermediate members 40. Then, raceway recesses 18 are formed on the side surfaces 163 of each raceway groove 16 so as to extend in a direction of a rotation axis of the outer ring. The shaft-like rolling elements 50 are fitted in the corresponding raceway recesses 18 and are able to roll along bottom surfaces 18a of the respective raceway recesses 18. Thus, the retainers 60 are arranged outside the raceway recesses 18. COPYRIGHT: (C)2010,JPO&INPIT |
