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 ring 16b of a thrust rolling bearing is supported so as to be able to pivotally displace by engaging a concave section 24 that is provided on the outside surface of the outer ring 16b with a cylindrical convex surface 22 of a support beam 23a of a trunnion 7b. Displacement of the outer ring 16b in the axial direction of the support beam 23a is limited by engaging a concave groove 27 that is formed around the inside surface of the concave section 24 in the circumferential direction around the support beam 23a with a protrusion 28 that is formed around the outer-circumferential surface of the support beam 23a.
