A perpendicular distance (PCR,) between a centerline (L,) including the center (O,) of the outer circumference surface (,) of an outer roller (,), orthogonal to axis Z of a trunnion (,) and a joint center O is shifted by &Dgr;h (&equals;PCR,&minus;PCR,) from a perpendicular distance (PCR,) between a centerline (L,) including the center (O,) of the outer circumference surface (,) of an inner roller (,), orthogonal to axis Z of a trunnion (,) and a joint center O. Under the most favorable conditions, PCR,is shifted by an optimal amount of &Dgr;H from PCR,toward the proximal end of the trunnion, and the position of contact (S) between the inner circumference surface (,) of the outer roller,and the outer circumference surface (,) of the inner roller (,) is located on the centerline (L,) (on PCR,) of the outer circumference surface (,) of the outer roller (,).

Constant velocity universal joint

An inner roller is rotatably fitted on a trunnion of a tripod member through a plurality of needle rollers and held in position against slipping off the trunnion by a slip-off preventing ring and a stopper ring mounted on the distal end of the trunnion.

Homokinetic universal joint having decreased induced thrust
