Patent ID: 8210950

Claim:
A torque fluctuation absorbing apparatus for absorbing a torque fluctuation generated between an engine and a transmission, comprising: a damper portion having: a first plate member; a second plate member including a first plate portion and a second plate portion to interpose therebetween the first plate member; and a plurality of coil springs provided between the first and second plate members, the plurality of coil springs arranged to compress when the first and second plate members move relative to each other thereby absorbing a torque fluctuation generated by a difference between a rotation of the first plate member and a rotation of the second plate member; and an auxiliary damper portion provided at a torque transmitting path to be established between the damper portion and an input shaft of the transmission at a position offset in an outer radial direction of the first and second plate members away from a position of the damper portion, wherein the first plate member is connected to an output shaft of the engine, the second plate member is connected to the input shaft of the transmission, and wherein the auxiliary damper portion generates a spring force for absorbing a torque fluctuation generated between the output shaft of the engine and the input shaft of the transmission, and the damper portion and the auxiliary damper portion are disposed at positions offset in an axial direction from each other, the auxiliary damper portion being closer to the second plate member than the damper portion in the axial direction.
