PROBLEM TO BE SOLVED: To reduce interference between a link and a power roller supporting member in a low side change gear ratio position and a high side change gear ratio position where the interference causes troubles, while changing simply a shape of a protrusion, and to suppress maximum torque sharing to a small level even when interfered by excessive input torque onto the power roller supporting member. SOLUTION: The protrusions provided in the both links 5, 6 to specify contact positions between trunnions 4, 4 and the links 5, 6 irrespective of cross angles between the trunnions 4, 4 and the links 5, 6 during stroke of the trunnions 4, 4 are arranged peripheries of spherical joint engaging holes 5b, 5b of the links 5, 6 and in a link outer side area, and are formed into circular arc-shaped protrusions 5c, 6c having curvature centers in engaging hole 5b, 6b portions.
