Abstract
A toroidal continuously-variable transmission includes a tilt rotation stopper structure to limit a range of rotation of a trunnion supporting a power roller in a toroidal cavity between input and output disks, so as to prevent contact points of the power roller with the input and output disks from deviating from respective rolling contact surfaces. The tilt rotation stopper structure includes a link-side stopper provided in a lower or upper link in a region separated from a left and right tilt rotation synchronizing wire, and a trunnion-side stopper provided in a side of an axial movement limiting member.
