摘要:
A toroidal continuously variable transmission includes: an input disk; an output disk; a plurality of power rollers; a plurality of trunnions; an oil pump; a pressing hydraulic mechanism that moves and brings the input disk and output disk closer to each other; a shifting hydraulic mechanism that moves the trunnions forward and rearward; and a hydraulic control device that controls the pressing hydraulic mechanism and the shifting hydraulic mechanism by oil pressure. The hydraulic control device has an oil pressure regulation unit that sets an oil pressure in a shifting hydraulic line that is a hydraulic source of the shifting hydraulic mechanism to an oil pressure at which shifting control can be performed by the shifting hydraulic mechanism till the transmission of power between the input disk and output disk is interrupted when the operation of the oil pump is stopped.
