Claims

[Scope of utility model registration request]

A fixed V pulley piece, a movable V pulley piece disposed on the axial extension of the fixed V pulley piece so as to be able to slide in the axial direction facing the fixed V pulley piece, and a movable V pulley piece on the back side of the movable V pulley piece. a fixed piece arranged and fixed on the shaft extension;
an outer extending portion extending toward the outer peripheral end of the movable V pulley piece and having a tip close to the outer peripheral end of the fixed piece; and an outer extending portion extending toward the outer peripheral end of the fixed piece and having a tip close to the movable V A plurality of balls for applying centrifugal force are housed in a space formed by the inner extension portion adjacent to the outer peripheral end of the pulley piece so as to be freely movable within the space. A centrifugal device in which pressure is generated on the back side of a movable V-pulley by the centrifugal force of the balls to cause the movable V-pulley to slide, thereby varying the width of the V-groove between the fixed V-pulley and the movable V-pulley. A centrifugal thrust type variable speed pulley, characterized in that a wall member forming a ball accommodating space has a hardness greater than the hardness of the centrifugal force applying balls.
