Claims

[Scope of utility model registration request]

a shaft having three tripod shafts extending in the radial direction from portions equally spaced in the circumferential direction;
A roller having a spherical outer peripheral surface, which is rotatably supported by each of the tripod shafts, and a casing surrounding the shaft, which extends in the axial direction of the shaft and has three grooves for inserting the tripod shafts and rollers. A groove member interposed between a casing having equal intervals in the circumferential direction, and the roller and each of the two wall surfaces of the grooves of the casing, the surface facing the roller having an arcuate cross section. A tripod type constant velocity joint comprising: a groove member having a roller groove exhibiting a roller groove; and a plurality of balls disposed between each groove member and each wall surface of each groove.
