Abstract

PURPOSE:To decrease axial length of a conical disc, by radially providing rollers to a rotary shaft, adapting partially arc shaped cams to the rollers and providing the cams to a piston inside of the vertical wall of a movable pulley. CONSTITUTION:Cams 12 are protrusively formed to a vertical wall 9 of a conical disc 7 slidable for a rotary shaft 1, and the cam comprises a cam surface 12a, engaged to a roller 25, and stepped part 12b, protruded like a staircase. Further three roller shafts 23 are radially mounted at an equal pitch to a roller mounting part 21 secured to a flange part 23 of the rotary shaft 1 through a key 22. Then rollers 25, having a spherical surface 25a, are rotatably mounted to each roller shaft 23 through roller bearings 24 further in a slidable state axially of the roller shaft 23. As a result, axial length of the conical disc can be decreased as compared with that the guide surface of a roller is provided to both sides of the conical disc and cylinder of a movable pulley.
