Abstract:
PURPOSE:To prevent the occurrence of uneven rotation and loss of transmission force by disposing a recess portion on the inner wall of either a driving portion or a driven portion and a projecting portion on the outer periphery of the other, pressing one of them to be fitted to each other by an elastic body, and then releasing the elastic action. CONSTITUTION:A pulley shaft 3 is provided with a driving portion 11 having a recess portion in the inner peripheral portion. A driven portion 12 has a projecting portion in the outer peripheral portion. When the driven portion 12 is inserted in the driving portion 11, the forward cylindrical portion with a diameter of DU is fitted to the cylindrical portion with a diameter of DO of the driving portion 11. When a phase difference is caused in connection of the recess and projecting portions, the driving portion 11 is pressed to the projecting portion of the driven portion 12 to bend an urging spring, so that the driving portion 11 integral with a pulley 5 has the recess portion rotated to the projecting portion of the driven portion 12 and fitted thereto by rotation of a belt 6. After that, a spring releasing member 14 is brought into contact with a spring release plate, so that spring pressure of the urging spring 10 to the pulley 5 is released.
