PROBLEM TO BE SOLVED: To provide a damper capable of reducing vibration in a bending direction having a different resonance frequency. SOLUTION: The hub 1 of this damper comprises a hub body 10 and a sleeve 14 fitted by pressure on the rim part 13 of the hub body. A ring-shaped mass 2 is coupled with the periphery of the sleeve 14 through a twisting direction resilient piece 3, and a plurality of bending direction masses 4 arranged at certain intervals in the circumferential direction confronting in the axial direction to the hub 1 are coupled in the axial direction with an inward directed flange 14d formed on the sleeve 14 through bending direction resilient pieces 5, while an auxiliary resilient piece 6 arranged at the periphery of each masses 4 with the gap G reserved in the radial direction is installed at an intermediate cylinder 14c at the periphery of the inward directed flange 14d, wherein the masses 4 are arranged contacting with the auxiliary resilient piece 6 by the centrifugal force at the time of rotating.
