To restrain the occurrence of force for inclining a roller, while restraining the occurrence of unbalance in pressing force acting on a contact part of the rollers.
A torque cam mechanism 25 is arranged only in a ring roller 22-1 among two ring rollers 22-1 and 22-2 for changing the pressing force acting on the contact parts 27, 28-1 and 28-2 in response to transmission torque, and the movement to the other side in the axial direction is restricted by a support member 18 on the ring roller 22-2. While allowing relative displacement in the axial direction of the ring roller 22-1 to the ring roller 22-2 by engagement of mutual splines 88 and 90 respectively arranged in the ring rollers 22-1 and 22-2, relative displacement in the peripheral direction of the ring roller 22-1 to the ring roller 22-2 is restricted.
