PROBLEM TO BE SOLVED: To eliminate the need of turning processing to reduce cost, and to facilitate sure slip-off prevention by a simple means.SOLUTION: The tripod type constant velocity universal joint includes: an outside joint member 10, which is in a shape of a cup having an opening part 11 at one end thereof, and has three track grooves 12 formed to an inside peripheral surface to be axially extended and roller guide faces 14 formed to an inner wall of each track groove 12 to be opposed to each other; a tripod member 20 having three leg shafts 22 radially projected; and roller units 30 rotatably supported by the leg shafts 22 of the tripod member 20, inserted in the track grooves 12 of the outside joint member 10 to be capable of rolling, and guided along the roller guide faces 14. The roller units 30 and the tripod member 20 are housed in the outside joint member 10 to be axially slidable. Retaining members 50 which are projected radially inside, and to which the leg shafts 22 of the tripod member 20 are locked, are disposed at a bottom part of the track groove 12 in the opening part 11 of the outside joint member 10. |
