Claims

[Claims for Utility Model Registration] 1. At least one of the opposing sheaves attached to the sheave shaft is a sliding sheave that moves in the axial direction, and this sliding sheave and a spring retainer located on the side of the sheave In a speed change pulley having a spring inserted between the pulley, a contact locking member is provided on at least one of the spring presser and the boss portion of the sliding sheave, and the spring has a conical shape, a drum shape, or a barrel shape. A speed change pulley characterized in that a coil spring is used, and an end of the spring is brought into contact engagement with the contact locking member. 2. The speed change pulley according to claim 1, wherein the contact locking member is a protruding pin. 3. The transmission pulley according to claim 1, wherein the contact locking member is a member having a high coefficient of friction. 4. The variable speed pulley according to claim 3, wherein the member having a high coefficient of friction is selected from rubber, polyurethane, resin, or a material mixed therewith with fibers.
