Claims

[Claims for Utility Model Registration] (1) A rotating shaft that is integrally attached to the output shaft of the engine, and a fixing member that is fixed to a wall integral with the rotating shaft and that constitutes 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 and forms a spring storage part together with the rotating shaft and is open at one end, and the outer cylinder 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 housing and presses the movable V-pulley toward the fixed V-pulley, and The base is fixed and contacts the side surface of the fixed V pulley with an uneven contact surface to form a torque cam, and has a conical surface on the outer circumferential side of the wall, and together with the wall, forms a particle storage section. a movable member that is formed, and a granule that is stored in the granule storage section and that applies a thrust to the movable member in a direction to expand the V groove of the V pulley by centrifugal force due to rotation of the rotating shaft. What is claimed is: 1. A centrifugal thrust type variable speed pulley comprising: a friction reducing means disposed on a contact surface between a fixed V pulley and a movable member constituting the torque cam. (2) The centrifugal thrust type variable speed pulley according to claim 1, wherein the friction reducing means is made of a needle-shaped thrust bearing, ceramic, Teflon, or the like having a low coefficient of friction.
