TORQUE FLUCTUATION ABSORBING DAMPER

摘要

PROBLEM TO BE SOLVED: To provide a torque fluctuation absorbing damper compatibly improving the durability of a second elastic body 32 and a torque fluctuation absorbing function by an inertial mass of a pulley 31. SOLUTION: The pulley 31 is provided with a pulley body part 311 extending from an internal circumferential cylinder part 313 relatively rotatably supported to the internal circumference of a hub 1 via a bearing 33 to the outer circumferential side of an annular mass body 21 via a disk part 312. The internal circumferential cylinder part 313 of the pulley 31 is elastically connected to the rim part 13 of the hub via the second elastic body 32. This constitution allows this damper to sufficiently take the inertial mass of the pulley 31 and sufficiently secure the diametrical direction of the second elastic body 32 so as to compatibly secure the superior torque fluctuation absorbing characteristics and the durability of the second elastic body 32.
