Abstract
A torque fluctuation absorbing apparatus for absorbing a torque fluctuation generated between an engine and a transmission includes a damper portion having a first plate member, a second plate member and a plurality of coil springs. The second plate member includes a first plate portion and a second plate portion to interpose therebetween the first plate member. The plurality of coil springs is provided between the first and second plate members. The plurality of coil springs is 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. The first plate member is connected to an output shaft of the engine. The second plate member is connected to an input shaft of the transmission.
