Patent ID: 7014588

Claim:
A toroidal-type continuously variable transmission, comprising: an input shaft; an input side disk including an inner surface and rotatable integrally with said input shaft; an output side disk including an inner surface, disposed coaxially with said input side disk, and rotatable independently of said input shaft; a plurality of trunnions interposed between said input side and output side disks and swingable about respective pivot shafts placed at twisted positions with respect to center axes of said input side and output side disks; a plurality of displacement shafts respectively projected out from inner surfaces of associated ones of said plurality of trunnions; a plurality of power rollers held by and between said inner surfaces of said input side and output side disks in such a manner that they can be rotatably supported on associated ones of said plurality of displacement shafts; and, a transmission member including a plurality of transmitting projection pieces on the base end portion thereof, wherein said projection pieces of said transmission member are fixed in an axial direction of the input side disk, wherein a plurality of projecting portions are provided on and projected from part of an outer surface of said input side disk, and said transmitting projection pieces of said transmission member are engaged with said projecting portions to thereby be able to transmit torque between said input side disk and said transmission member, wherein said projecting portions are slidable, in the axial direction of the input side disk, with respect to said projection pieces.
