The invention provides a torus-type continuously variable transmission, which gear ratio can be maintained after the engine is stopped simultaneously improve responsiveness for starting to shift. The torus type continuously variable transmission (T) comprising: a pump (41), which is driven by an internal combustion engine (E); a first passage (P1), which (46) the oil pump via a first pressure regulating member a hydraulic pressure supplied to the hydraulic actuator (33) is a growth oil chamber (37); a second passage (P2), which generates the hydraulic pump is supplied to the second pressure regulator via a member (50) the hydraulic actuator a decelerating oil chamber (38); and a pressure accumulator (48, 52), which is connected to at least one of the first oil passage and the second oil passage. When the engine is stopped, will be accumulated in the accumulator hydraulic pressure is supplied to the oil chamber or slow down the growth rate of oil chamber, and therefore even if the engine is stopped and the supply of hydraulic pressure from the oil pump interruption, it is possible to use the accumulator in accumulated hydraulic hydraulic actuator action.
