Abstract
A plural cavity toroidal transmission is designed to permit transmission of great torque between output side disks and a sleeve while maintaining a thickness of the sleeve. To this end, convex portions are formed on outer surfaces of the output side disks and concave portions are formed on edge portions of both axial ends of the sleeve. By fitting the convex portions into the concave portions, synchronous rotations of the pair of output side disks and transmission of rotation from the output side disks to an output gear can be achieved.
