Abstract
Provided is a pressing device for toroidal continuously variable transmission capable of reducing hysteresis that occurs between torque and pressing force. An intermediate sliding memberis provided in at least one location of a portion between an end surface on the outside in the radial direction of the retainerof the rollerarranged on the outermost side in the radial direction and an inside surface of the pocketon the outside in the radial direction, and a portion between an end surface on the outside in the radial direction of the retainerof one rollerof adjoining rollersin the radial direction and an end surface on the inside in the radial direction of the retainerof another roller. As a result, the contact area of a sliding contact portionis made smaller than in a case where an intermediate sliding memberis not provided.
