A chain (endless flexible member) is looped over an input pulley and an output pulley. Each of the input pulley and the output pulley includes a pair of a fixed sheave and a movable sheave. The fixed sheave and the movable sheave have tapered faces that are opposed to each other to define a V-shaped groove. A vibration damping plate (vibration damping member) is fixed to each fixed sheave, and is in contact with the outer peripheral face of the fixed sheave. When the fixed sheave vibrates, the vibrations are damped by the friction between the outer peripheral face of the fixed shave and the vibration damping plate.
