Sliding-type tripod constant velocity joint

摘要

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 are able to circulate around the corresponding intermediate members 40 and are able to roll between side surfaces 162 and 163 of a corresponding one of raceway grooves 16 of an outer ring 10 and a torque transmitting surface 41b of a corresponding one of the intermediate members 40. Then, raceway recesses 17 and 18 are formed on the side surfaces 162 and 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 17 and 18 and are able to roll along bottom surfaces 17a and 18a of the respective raceway recesses 17 and 18. Thus, the retainers 60 are arranged outside the raceway recesses 17 and 18.
