Claims

[Scope of utility model registration request]

(1) In the boot 9-, which has a boss provided at the center of the pulley body and an inertia mass provided on the outer periphery of the boss via an elastic body, the inertia mass is arranged concentrically inside the center hole. By expanding the diameter of the medium ring, an elastic body is sandwiched between the inner circumferential surface of the inertia mass and the outer circumferential surface of the medium ring, and the boss is press-fitted onto the inner circumferential surface of the medium ring. pulley.

(2) Either or both of the inner circumferential surface of the inertia mass and the outer circumferential surface of the medium ring are configured to narrow the opening edge so as to prevent the elastic body interposed between them from escaping. A pulley according to claim 1 of the utility model registration claim, characterized in that:

(3) A utility model characterized in that one or both of the inner circumferential surface of the inertia mass and the outer circumferential surface of the medium ring has an anti-slip portion that comes into contact with the elastic body interposed between them. A pulley according to registered claim 1 or 2.
