Claims

[Scope of utility model registration request]

A fixed piston is fixed to the rotating shaft that supports the movable sheave, and a cylinder that can slide freely relative to the fixed piston is provided behind the movable sheave.The movable sheave side of the fixed piston is used as a hydraulic chamber, and the opposite side is used for centrifugal hydraulic pressure correction. In a pulley for a V-belt continuously variable transmission having a secondary chamber, one end of the fixed piston is stopped by a stopper surface of a rotating shaft, and the other end of the fixed piston is stopped by a spacer having a tapered disc spring part. A snap spring which is elastically supported and has an inner diameter part of a diaphragm whose outer diameter part is fixed to a cylinder outside the spacer, and a retainer that holds the inner diameter part, and which is attached to a rotating shaft with the spacer and retainer. A seal structure for a pulley for a V-belt continuously variable transmission, which is characterized in that it is simultaneously supported by .
