Abstract:
A toroidal continuously variable transmission includes: an input disc; an output disc; a power roller; a trunnion; a support that supports the power roller such that the power roller is rotatable relative to the trunnion; a thrust bearing that receives a load of the rotating power roller in a direction along a rotation axis of the power roller; and an oil passage through which lubricating oil is supplied to the thrust bearing. An opposing surface of the power roller which surface is opposed to the support includes a first bearing groove. An opposing surface of the support which surface is opposed to the power roller includes a second bearing groove. A virtual axis of a discharge port of a nozzle included in the oil passage reaches a bearing groove that is one of the first bearing groove and the second bearing groove. When viewed from a direction perpendicular to the direction along the rotation axis, a portion of a retainer which portion is 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 respective sides opposite to each other across the virtual axis and away from the virtual axis.
