DAMPER PULLEY, METHOD OF PRODUCING DAMPER PULLEY, AND VARIABLE DISPLACEMENT VANE PUMP

摘要

[PROBLEMS] A damper pulley can cope with vibration of not only in the radial direction of the pulley but also in the axial direction and allows easy mounting of a rubber-like elastic body in the pulley. [MEANS FOR SOLVING THE PROBLEMS] The damper pulley includes a pulley body having a boss that is connected to a drive shaft, a flange that extends from the boss in the direction of the outer diameter of the drive shaft, and a rim that is provided on the outer peripheral side of the flange and is formed in an annular shape; an elastic body provided on the pulley body and having a radial section that extends in the radial direction and also having an axial section that extends in the axial direction; and a mass member provided on the elastic body and movable relative to the pulley body.
