A toroidal-type continuously variable transmission includes first and second disks, a trunnion and a power roller. The first and second disks are coaxially and rotatably supported in a state that inner surfaces thereof are opposed to each other. The trunnion swings around a pivot shaft which is disposed at a torsional position with respect to a center shaft of the first and second disks. The power roller is sandwiched between the first and second disks in a state being rotatably supported at inner surface of the trunnion. The power roller has a first shaft portion which is protrusively provided at a center portion of an outer surface thereof in a coaxial manner with the power roller, and the power roller is rotatably supported by the first shaft portion.
