Abstract:
Provided is a toroidal continuously variable transmission capable of ensuring the workability and conveying ability of a power roller inner ring while suppressing hydraulic leakage from the inner end face of the power roller inner ring and reduction in rigidity of the power roller inner ring. A power roller 40 of the toroidal continuously variable transmission includes: a power roller inner ring 50 sandwiched between two discs 1, 2; a power roller outer ring 60 provided to a trunnion 35 and rotatably supporting the power roller inner ring 50; and an inner ring opening 52 formed in the power roller inner ring 50 so as to extend in the axial direction. An end face opening 58 communicating with the inner ring opening 52 is formed in an inner end face 54 of the power roller inner ring 50. The end face opening 58 is blocked by a blocking member 80 provided separately from the power roller inner ring 50.
