Abstract:
1. A tripod constant velocity joint comprising: a tubular outer member for connection to a transmission shaft, said tubular outer member having a plurality of guide grooves defined in an inner wall surface thereof that are spaced from each other and extend in an axial direction of the tubular outer member; an inner member for connection to another transmission shaft, said inner member being disposed in an opening defined in said tubular outer member; said inner member having a plurality of trunnions projecting respectively into said guide grooves; a ring-shaped roller fitted over each of said trunnions and held in contact with surfaces defining said guide grooves; a plurality of rolling elements rollingly interposed between each of said trunnions and said roller, said roller having an inner circumferential wall surface; a one-sided flange projecting radially from an axial end of said inner circumferential wall surface; and a holder mounted in an opposite axial end of said inner circumferential wall surface and holding said rolling elements, wherein before said holder is mounted in said roller, said roller is configured to receive simultaneously all rolling elements configured as an annular array, all of the rolling elements are configured to be placed onto said inner circumferential wall surface in an axial direction of said inner circumferential wall surface, which is a direction opposite to said one-sided flange, and the rolling elements are retained in place.
