PROBLEM TO BE SOLVED: To suppress the divergence of a skew angle.SOLUTION: A continuously variable transmission 1 constituted by planetary balls 40 and the like, comprises: a non-rotatable first guide member 50A including a first guide portion 51 guiding a first protrusion portion 41a; a rotatable second guide member 50B including a second guide portion 52 guiding a second protrusion portion 41b; a gear change member 50C including a gear change portion 53 keeping balance between a force on a sidewall of the gear change portion 53 and a force on the second protrusion portion 41b during normal rotation and allowed to rotate by a first actuator 81; a second actuator 82 prohibiting the second guide member 50B from rotating during reverse rotation and allowing the second guide member 50B to rotate during normal rotation; a third actuator 83 allowing the second guide member 50B to rotate up to a stop position during reverse rotation; and a connection/disconnection device cutting off power transmission of the third actuator 83 during normal rotation, a difference in magnitude between the second guide portion 52 and the second protrusion portion 41b being set so that, in a state in which the second protrusion portion 41b contacts the second guide portion 52 by a circumferential force during the reverse rotation, the second protrusion portion 41b does not contact the gear change portion 53 in a direction of the force. |
