Abstract:
1. A fluctuation absorbing apparatus, comprising: a first plate fixed to a flywheel, the flywheel being rotatable around a rotation axis; a second plate disposed at a distance from the first plate; a third plate slidably sandwiched between the first plate and the second plate; a resilient section that is supported by, fixed to or integrated with the first plate or the second plate and biases the second plate toward the first plate; a damper unit that absorbs fluctuating torque; a hysteresis unit that absorbs the fluctuating torque; wherein one plate of the first and second plates has a plurality of holes or recesses; wherein the resilient section is an annular disc spring supported by said one plate; wherein the other plate of the first and second plates includes a plurality of support parts, each extending from the other plate, the plurality of support parts receiving a pressing force of the annular disc spring; wherein the annular disc spring is sandwiched between the support parts and the one plate; and wherein in a radial direction of the first plate, a distance from the rotation axis to a contact portion of the resilient section in the support parts is greater than a distance from the rotation axis to an end of the third plate.
