ABSTRACT:
A torque fluctuation damper pulley10is provided with a torque fluctuation damping elastic member15between a hub11attached to a rotational shaft and a pulley member13. The torque fluctuation damping elastic member15includes a pair of rubber members15A and15B which sandwich a support portion24of the pulley member13under equal elastic forces from the front and rear in the axial direction of the pulley member13to joint the hub with the pulley member13elastically. Thus, the pulley member13always has equal forces being applied thereto from the front and rear in the axial direction, so that it becomes possible to make unnecessary any thrust bearing which would otherwise be required for positioning the pulley member13in the axial direction.
