Abstract
Construction of a toroidal continuously-variable transmission is achieved that simplifies the manufacture of parts, management of parts and assembly work, is able to easily reduce costs, stabilizes speed change operations, and is processed easily. An outer ringof a thrust rolling bearing is supported so as to be able to pivotally displace by engaging a concave sectionthat is provided on the outside surface of the outer ringwith a cylindrical convex surfaceof a support beamof a trunnion. Displacement of the outer ringin the axial direction of the support beamis limited by engaging a concave groovethat is formed around the inside surface of the concave sectionin the circumferential direction around the support beamwith a protrusionthat is formed around the outer-circumferential surface of the support beam
