A constant velocity joint comprises: a hollow housing having a plurality of guide grooves; a tripod having a plurality of trunnions positioned in the guide grooves; and a roller assembly disposed on each trunnion. The outer roller includes a convex outer surface, the convex outer surface having a first radius (Rry) seen from a cross section taken in an orthogonal direction of the outer roller, the convex outer surface having a second radius (Rrx) seen from a cross section taken along the central axis of the outer roller, in which the center of the second radius (Rrx) is displaced outwardly from the center of the first radius (Rry), and the second radius (Rrx) is shorter than the first radius (Rry). |
