摘要：A belt-drive CVT (3) includes a pair of pulleys (21,22), each of which has astationary pulley (21a,22a) and a movable pulley (21b,22b) that moves toward or awayfrom the stationary pulley in an axial direction of the pulley, a belt (23) that is woundaround the pair of pulleys and a rotation state detecting device for detecting rotation ofthe pulley. The rotation state detecting device has a tone wheel (25) that rotatesintegrally with the pulley (22) and a sensor (KS2) that faces the tone wheel. The tonewheel has a cylinder portion (25b;25b';25b\") that extends along a moving direction of themovable pulley. The cylinder portion is provided with a plurality of detection portions(26;27;28) which are arranged at regular intervals in a circumferential direction throughoutan entire circumference of the cylinder portion and which extend along the movingdirection of the movable pulley.
