Abstract
A pressing device for a toroidal continuously variable transmission, comprises: a disk having a toroidal curved surface and a first cam surface; a cam plate having a cylindrical portion, and an outward facing flange portion having a second cam surface; and a plurality of rolling bodies. The cylindrical portion has a cylinder portion, a projection projecting inward in the radial direction in one axial end portion of the cylinder portion and having a step surface, and an oil supply passage. At least a part of a radial inside opening of the oil supply passage opens to a portion of the cylinder portion positioned further on the other side in the axial direction than the step surface. The oil supply passage has an oil-passage hole penetrating the cylinder portion and an oil-passage groove continuous with the oil-passage hole and recessed from the step surface.
