The continuously variable transmission (T) of the present invention includes a drive face 29 and an output shaft 22 supported on an outer circumference of the input shaft 23. Driven face 30 supported on the outer periphery of the plurality of cones, a plurality of double cones 39 supported by the cone holders 31 and 56 and abutting the two faces 29 and 30, the casing 1 and the cone holder 31. And a torque cam mechanism 33 disposed between the 55 and 55. The torque cam mechanism 33 is formed so as to be inclined with the axis L on the inner wall of the casing 1 and the roller 36 disposed on the cone holders 31 and 56, and the guide groove 4 on which the roller 36 is engaged. 1 ), and when the input torque of the cone holders 31 and 56 changes, the cone holders 31 and 56 move in the direction of the axis L by the reaction force received by the roller 36 from the guide groove 4 1 .
