とするベルト式無段変速機。[Claims for Utility Model Registration] A fixed rotating body fixed to a rotating shaft, a cylindrical boss part fitted to the rotating shaft, and a disk part protruding outward from a part of the boss part. a variable pulley including a movable rotary body that is movable in the axial direction but not rotatable about the axis while facing the fixed rotary body; and a hydraulic oil chamber located on the back side of the movable rotary body. and a hydraulic cylinder that applies a thrust to the movable rotating body based on the pressure of hydraulic oil supplied to the hydraulic oil chamber through an axial oil passage formed in the axial direction within the rotating shaft, A type in which a pin mechanically associated with a gear ratio detection valve provided within the shaft is fixed to the movable rotating body through an elongated hole formed radially through the rotating shaft. In the belt-type continuously variable transmission, the hydraulic oil chamber of the hydraulic cylinder and the axial oil passage are communicated through an oil hole formed in the radial direction in the boss portion and the elongated hole. Belt type continuously variable transmission.
