PROBLEM TO BE SOLVED: To provide a degree of corresponding freedom in layout, concerning a transmission mechanism of a continuously variable transmission.SOLUTION: A transmission mechanism of a continuously variable transmission is equipped with two pulleys having a fixed sheave and a moving sheave; a flexible member wound around the two pulleys; and an energizing mechanism provided on one of the pulleys, and energizing the moving sheave in a direction coming close to the fixed sheave. The transmission mechanism has a screw shaft 82 rotation-driven by a transmission motor 81, a nut portion 71 moving along the screw shaft 82, and a pulley drive member 10 provided with an engaging portion 11 engaged with the nut portion 71 and rotated about a rotary axis Cof the other pulley by the movement of the nut portion 71 to move the moving sheave of the other pulley in an axial direction. The engaging portion 11 has at least a main claw portion 13 provided on a side on which the nut portion 71 abuts when the moving sheave of the other pulley is moved in a direction separating from the fixed sheave.SELECTED DRAWING: Figure 2 |
