Patent ID: 7993206

Claim:
A torque fluctuation absorber, comprising: an output plate that is rotatably disposed; a first rotating plate that is disposed so as to be movable relative to the output plate in a direction of rotation of the output plate; a first elastic member that is engaged with the output plate and the first rotating plate, and that is capable of transmitting power applied to the first rotating plate to the output plate; a second elastic member to which power from a power source is applied and which is capable of transmitting the applied power to the first rotating plate; a power transmission control mechanism that is capable of controlling torque to be applied to the first rotating plate, wherein the power transmission control mechanism is disposed on an outer side of the first elastic member in a radial direction of the output plate, and wherein the second elastic member is disposed so as to be spaced from the first elastic member and the power transmission control mechanism in a direction of an axis of rotation of the output plate, and is disposed on an open side of a recess defined by the power transmission control mechanism and first rotating plate.
