ABSTRACT:
A toroidal-type continuously variable transmission which includes: a casing; input and output disks respectively including inner surfaces, disposed concentrically with each other inside the casing, and supported so as to rotate independently of each other; a plurality of trunnions each including even-numbered pivot shafts existing at right angles to a central-axis direction of the disks and disposed concentrically with to in parallel to each other, and being swingable about the pivot shafts; a plurality of shift shafts respectively projected out from the trunnions; a plurality of power rollers held by and between respective inner surfaces of the disks so as to be rotatably supported on the shift shafts; and a support member fixed directly to the casing and supporting the pivot shafts so as to be shifted in an axial and an inclined rotation direction thereof.
