PROBLEM TO BE SOLVED: To suppress the divergence of a skew angle.SOLUTION: A continuously variable transmission comprises: first to third power transmission members 10, 20, 30; a plurality of planetary balls 40; a non-rotatable guide member 50A including a first guide portion 51 guiding a first protrusion portion 41a of a support shaft 41 of each planetary ball 40 in a radial direction; a rotatable gear change member 50B rotatable in a circumferential direction and including a gear change portion 52 whose longitudinal direction is inclined with respect to the radial direction so as to keep balance between a force acting on the second protrusion portion 41b and a force acting a sidewall of the gear change portion 52 during normal rotation; a first actuator 81 rotating the gear change member 50B; a locking member 90 rotatable in the circumferential direction, and including a locking portion 93 locking the second protrusion portion 41b during reverse rotation; and a second actuator 82 rotating the locking member 90 to cause the locking portion 93 to lock the second protrusion portion 41b during reverse rotation, and rotating the locking member 90 to retreat the locking portion 93 to a position out of contact with the second protrusion portion 41b during normal rotation. |
