ABSTRACT:
A pulley assembly of a belt type continuously variable transmission having a stationary sheave, a moving sheave and a hydraulic actuator connected at an edge thereof with the moving sheave for controlling a groove width between the stationary sheave and the moving sheave comprises, an annular groove provided at the back face of the moving sheave and an annular projection provided on the bottom surface of the annular groove for regulating a plastic flow of the edge into a fork-shape when the edge is caulked into the annular groove. Thus constituted structure of the pulley assembly provides an enough connecting strength between the hydraulic actuator and the moving sheave with a small amount of caulking.
