PROBLEM TO BE SOLVED: To provide a toroidal continuously variable transmission inhibiting or preventing local wear of abutting portions between the cam surface of a precess cam that is displaced according to the inclined rolling state of a power roller and a feedback link serving as the cam follower of the cam and the resulting generation of worn powders, being easy to fabricate, and capable of enhancing its durability. SOLUTION: An abutment part 55 that abuts against the cam surface 54 of a precess cam 52 is separate from a feedback link 53 and formed into a three-dimensional curved surface as a barrel-shaped rotor, so that even if the cam surface 54 of the precess cam 52 is tilted, a corner part does not collide against it. Also, a shank extended from the abutment part 55 is freely rotationally attached to the feedback link 53 and thus brought into rolling contact with the cam surface 54 to enhance durability. All of these members are formed into the rotating bodys whereby machinability on a lathe, etc., is enhanced. |
