PROBLEM TO BE SOLVED: To provide a torque variation absorbing damper wherein both sufficient durability of a second elastic body 33 in a coupling part 3 and reduction in redial size are secured. SOLUTION: A dynamic damping part 2 has a structure where an annular mass body 21 is elastically connected to an outer peripheral cylinder 13 of a hub 1 via a first elastic body 22. The coupling part 3 has a structure where a disk part 312 extending from an axial one end to the inner peripheral side of a pulley 31 supported on the outer periphery of the annular mass body 21 relatively rotatably via a bearing 34 is axially elastically connected to a collar part 32b of a metal ring 32 mounted to a boss part 11 of the hub 1 via the second elastic body 33. The durability is secured by setting sufficient axial thickness of the second elastic body 33 between the disk part 312 and the collar part 32b. COPYRIGHT: (C)2004,JPO
