ABSTRACT:
A toroidal-type continuously variable transmission, includes: a trunnion including: a support plate portion; and a pair of bent wall portions formed in longitudinal-direction two end portions of the support plate portion and bent on an inner surface side of the support plate portion, the pivot shafts being disposed concentrically with each other on outer surfaces of the bent wall portions; a trunnion shaft formed integrally with the pivot shaft; an oil pressure piston fitted with an outer peripheral surface of the trunnion shaft for moving the trunnions along the axial direction of the pivot shaft; and, a cut-away portion formed in the outer peripheral surface of the trunnion shaft for forming, between the cut-away portion and the oil pressure piston, an oil passage for a lubricating oil to be supplied to the bearing for a power roller.
