Claims

[Claims for Utility Model Registration] A fixed rotating body having a tapered belt contacting surface and fixed to a rotating shaft, a belt contacting surface opposite to the belt contacting surface of the fixed rotating body, and a side opposite to the belt contacting surface. two sets of variable pulleys with variable effective diameters, each comprising a cylindrical portion protruding in the axial direction from the rotary shaft, and a movable rotary body disposed on the rotary shaft so as to be movable in the axial direction but not rotatable around the shaft; A transmission belt is wound around the two sets of variable pulleys, while a cylinder plate fixed to the rotating shaft is slidably fitted into the cylindrical portion of the movable rotating body, and the cylinder plate and the movable rotating body are connected to each other. A thrust force is generated in the movable rotating body by supplying working hydraulic pressure into a hydraulic chamber surrounded by In a belt-type continuously variable transmission in which an inward annular groove for suppressing the influence of centrifugal oil pressure is provided between the cylinder plate and the annular wall, the lubricant is supplied to a bearing that supports the rotating shaft. A belt type continuously variable transmission characterized by being provided with a receiver that receives oil and guides it to the annular groove.
