Abstract
A toroidal type continuously variable transmission is provided which allows the outer peripheral face of power rollers to be processed by industrial techniques, and prevents an outer ring and a retainer from rubbing against an input side concave surface or an output side concave surface. The outer peripheral face of the power roller is formed of a spherical surface portion and a cylindrical surface portion continuous from a larger diameter side of the spherical surface portion, and the outer diameter of the cylindrical surface portion is selected to be longer than the outer diameter of the outer ring and the outer diameter of the retainer.
