PROBLEM TO BE SOLVED: To avoid or relax the generation of an edge load on the contact surface of inner rollers with rolling elements. SOLUTION: A constant speed joint comprises a plurality of trunnions 26a to 26c which swell toward guide grooves 18a to 18c and have revolving spherical surfaces 30, inner rollers 36 which have a pair of cutout portions 48a, 48b formed on their inner surfaces so as to face to each other and so as to have circular arc-shaped cross sections, and have inner spherical surfaces 38 formed so as to correspond to the spherical surface 30, and outer rollers 42 fitted on the inner rollers 36 via needle bearings 40, wherein outside diameter surfaces 37 of the inner rollers 36 are set so as to have such convex shapes that their axial curvatures (1/r2) are larger than their circumferential curvatures (1/r1).
