PROBLEM TO BE SOLVED: To achieve a simple and low-cost structure, properly maintaining the contact state between the peripheral surface of a power roller 8b and the respective disks regardless of a change in the elastic deformation amount of the respective structural members by displacing the power roller 8b in the axial direction of each disk. SOLUTION: The intermediate part of a trunnion 9b is provided with a support beam part 34 having a cylindrical projecting surface 33. A partial cylindrical recessed part 38 provided on the outside surface of an outer ring 37 constituting a thrust ball bearing 36 supporting the power roller 8b and the cylindrical projecting surface 33 of the support beam part 34 are engaged with each other. The outer ring 37 and the power roller 8b are supported in such a way that they make rocking displacement to the trunnion 9b in the axial directions of both input and output side disks.
