摘要:
A belt-drive CVT includes a pair of pulleys, each of which has a stationary pulley and a movable pulley that moves toward or away from the stationary pulley in an axial direction of the pulley, a belt that is wound around the pair of pulleys and a rotation state detecting device for detecting rotation of the pulley. The rotation state detecting device has a tone wheel that rotates integrally with the pulley and a sensor that faces the tone wheel. The tone wheel has a cylinder portion that extends along a moving direction of the movable pulley. The cylinder portion is provided with a plurality of detection portions which are arranged at regular intervals in a circumferential direction throughout an entire circumference of the cylinder portion and which extend along the moving direction of the movable pulley.
