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 member 27 is provided in at least one location of a portion between an end surface on the outside in the radial direction of the retainer 13 of the roller 14 arranged on the outermost side in the radial direction and an inside surface of the pocket 25 on the outside in the radial direction, and a portion between an end surface on the outside in the radial direction of the retainer 13 of one roller 14 of adjoining rollers 14 in the radial direction and an end surface on the inside in the radial direction of the retainer 13 of another roller 14. As a result, the contact area of a sliding contact portion 32 is made smaller than in a case where an intermediate sliding member 27 is not provided.
