PROBLEM TO BE SOLVED: To sufficiently increase a thrust generated in a torque cam in accordance with torque to be transmitted.SOLUTION: A pulley 2 has: a stationary sheave 11 integrated with a rotation shaft 13; and a movable sheave 12 fitted with the rotation shaft 13 movably forward and backward in an axial line direction so that it approaches to and is isolated from the stationary sheave 11. A thrust mechanism of a belt-type stepless transmission is provided with: a torque cam 26 for generating a thrust for pressing the movable sheave 12 toward the stationary sheave 11 in accordance with torque; and a spring 25 for pressing the movable sheave 12 toward the stationary sheave 11. The thrust mechanism has a rotation member 15 that gives and receives the torque between it and the pulley 2, and can relatively rotate around the rotation shaft 13. The torque cam 26 is provided between the rotation member 15 and the movable sheave 12, and the spring 25 is arranged between the rotation shaft 13 and the movable sheave 12 to press the movable sheave 12 toward the stationary sheave 11. |
