Abstract: A trunnion of a toroidal-type continuously variable transmission has a support plate portion for supporting a displacement shaft and a pair of bent wall portions respectively bent toward the inner surface side of the support plate portion. The support plate portion and the pair of bent wall portions cooperates together in defining a pocket portion for storing a power roller therein. Pivot shafts are disposed concentrically with each other on the outer surfaces of the pair of bent wall portions. The pair of bent wall portions are connected together by a connecting member. The connecting member includes a pressure receive portion contactable with the inner surface of the pocket portion in a direction intersecting substantially at right angles to the thrust direction and receiving a pressing force acting on the pocket portion to crush the pocket portion.
