A toroidal-type continuously variable transmission has a casing; a rotary shaft; a pair of outside disks each including an axial-direction one-side surface and supported on the rotary shaft so as to be rotated in synchronization with the rotary shaft; an inside disk including axial-direction two-side surfaces and rotatably supported on the periphery of the middle portion of the rotary shaft so as to be rotated with respect to the rotary shaft; support members disposed between the one side axial-direction surface and the axial-direction one-side surface so as to be swung and shifted about pivot shafts thereof; power rollers rotatably supported on the support members, the peripheral surface of the power rollers being contacted with the axial-direction two-side surface and the axial-direction one-side surface; and ball bearings for supporting the inside disk in such a manner that the inside disk is rotated with respect to the casing.
