Abstract
A toroidal continuously variable transmission including a power roller; a support supporting the power roller rotatably; a thrust bearing receiving a load of the power roller in a direction along a rotating axis; and an oil passage supplying lubricating oil to the thrust bearing. A surface of the power roller opposing the support includes a first bearing grooved and the support opposing the power roller includes a second bearing groove. A virtual axis of a discharge port in the oil passage reaches a bearing groove that is one of the first bearing groove and the second bearing groove. Viewed from a direction perpendicular to the rotation axis, a portion of a retainer located at a radially inner side of a retaining hole of the retainer and a portion located at a radially inner side of the bearing groove are located at sides opposite to each other across the virtual axis.
