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.

摘要： A sliding-type tripod constant velocity joint that includes needle units, each of which is able to prevent rolling elements from falling off in a state where the rolling elements are introduced in a cage, is provided. Each cage (60) of a constant velocity joint (1) forms circulation paths that are trajectories of circulating rolling elements (50), and is formed of a pair of first circulation path forming member (70) and second circulation path forming member (80) that are coupled to face each other so as to respectively support both axial ends of the rolling elements (50). Then, at least one of the circulation path forming members (70 (80)) has a window portion (75 (85)) that is open so as to be able to introduce the rolling elements (50) laterally with respect to a circulating direction into the circulation paths and a rib portion(76 (86)) that is formed so as to extend from a periphery of the window portion (75 (85)) in an introducing direction in which the rolling elements (50) are introduced. After the rolling elements (50) are introduced into the circulation paths, the rib portion (76 (86)) is calked toward an opening of the window portion (75 (85)) such that the rolling elements (50) do not pass through the window portion (75 (85)).

摘要： PROBLEM TO BE SOLVED: To provide a sliding type tripod constant velocity joint of a needle circulation type improving seizure resistance at contacts between intermediate members and tripod shaft portions. SOLUTION: The sliding type tripod constant velocity joint includes: an outer ring 10 having three raceway grooves 16 in the inner peripheral face; the tripod 20 having the three tripod shaft portions 22 inserted in the raceway grooves 16; the intermediate members 40 provided rockably around the outer peripheries of the tripod shaft portions 22; a plurality of shaft-like rolling elements 50 provided between the side faces of the raceway grooves 16 and the intermediate members 40 for rolling along the side faces of the raceway grooves 16; and cages 60 supporting the shaft-like rolling elements 50 so that the shaft-like rolling elements 50 can circulate around the outer peripheries of the intermediate members 40. An axial cross-sectional shape of the outer peripheral face of the tripod shaft portion 22 is formed in a convex curve convexed toward an inner power transmission face 43a of the intermediate member 40 and, in the inner power transmission face 43a, a cross-sectional shape in the axial direction of the tripod shaft portion 22 at the joint angle of 0° is formed in a straight shape.
