Claims

[Scope of utility model registration request]

a fixed sheave fixed to rotate integrally with the shaft, and a movable sheave rotatable integrally with the shaft and movable in the axial direction, and driving and driven pulleys transmitting power via a belt; It is attached in relation to one of the movable sheaves and moves radially outward in response to the centrifugal force generated by the rotation of the shaft, and exerts an axial pushing force on the one movable sheave through cooperation with the inclined cam surface. In the centrifugal continuously variable transmission, the centrifugal continuously variable transmission is configured to change the diameter of both pulleys in response to changes in the rotational speed of the shaft, and is configured to continuously variable speed, the guide cam having the inclined cam surface. is provided with a rear surface in contact with the one movable sheave so as to rotate integrally with the movable sheave and to be movable in the axial direction, and the other inclined cam surface cooperating with the inclined cam surface via the flyweight moves in the axial direction. A centrifugal continuously variable transmission characterized by being fixedly installed.
