Claims

[Claims for Utility Model Registration] (1) A rotating shaft provided integrally with the output shaft of the engine, and a fixing member fixed to a wall integral with the rotating shaft and forming one side of the variable speed V-pulley. a V-pulley, an outer cylinder whose base is fixed to the outer periphery of one end of the rotating shaft, forms a spring storage part together with the rotating shaft and is open at one end, and is slidably fitted onto the outer periphery of the outer cylinder. A movable V-pulley that forms a V-groove of a variable speed pulley together with the fixed V-pulley, a compression spring that is stored in the spring storage portion and presses the movable V-pulley toward the fixed V-pulley, and a compression spring that is attached to the movable V-pulley. The base is fixed and the fixed V
a movable member that contacts the side surface of the pulley with an uneven contact surface to form a torque cam, has a conical surface on the outer circumferential side of the wall body, and forms a grain storage section together with the wall body; The V is stored in the granule storage section and is caused by centrifugal force due to rotation of the rotating shaft
A centrifugal thrust type variable speed pulley having particles that apply a thrust to the movable member in the direction of expanding a V-groove of the pulley, characterized in that a friction reducing means is disposed between the compression spring and the movable V-pulley. Centrifugal thrust type variable speed pulley. (2) The centrifugal thrust type speed change pulley according to claim 1, wherein the friction reducing means is made of a thrust bearing, ceramic, Teflon, or the like having a low coefficient of friction.
