PROBLEM TO BE SOLVED: To enable, in a V-belt type continuously variable transmission in which, to a movable sheave allowed to approach to or separate from a fixed sheave, a holding member formed of a harder material than the movable sheave is fixedly installed, and a rolling bearing is provided between an output member and the holding member to allow movement of the output member driven by an actuator to be transmitted to the movable sheave, reduction in the size of the periphery of the movable sheave when fixedly installing the holding member to the movable sheave.SOLUTION: A casting-molded movable sheave 62 integrally comprises a cylindrical boss part 62a arranged coaxially with a rotating shaft 24, and a flange part 62b which projects radially outward from one end of the boss part 62a to hold a V-belt 59 between the flange part and a fixed sheave 61. A holding member 85 is casted to the outer periphery of the boss part 62a. |
