摘要： A continuously variable transmission includes a transmission ratio changing unit that can change a transmission ratio as a rotation speed ratio of an input disc and an output disc by tiltably rotating a power roller, a nip-press unit that can apply nip-pressure that nips the power roller between the input disc and the output disc by a pressure of a working medium supplied from a hydraulic pressure controlling unit that controls the pressure of the working medium to a nip-pressure generation hydraulic chamber via a coupling oil passage, and a pressure release unit which is disposed to the coupling oil passage and can release the pressure of the working medium of the nip-pressure generation hydraulic chamber via the release unit in response to an operation state, wherein since the release unit is positioned upward in a vertical direction of the nip-pressure generation hydraulic chamber in a state that the pressure release unit is mounted on a vehicle, the pressure release unit can appropriately prevent an unintentional transmission shift.

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.
