摘要：
The invention relates to a continuously variable transmission having a V-belt wound around a drive pulley and a driven pulley.
The invention aims to provide a cooling structure for a V-belt type continuously variable transmission which can increase a cooling effect for a V-belt.
The invention proposes to improve the continuously variable transmission in that plural radiation fins are formed in substantially concentric cycles on an external surface of the driven pulley.
