Patent ID: 7766752

Claim:
A torque fluctuation absorbing apparatus provided between a driving source and a transmission and transmitting torque from the driving source to the transmission, the apparatus further absorbing fluctuations in the torque transmitted and limiting a maximum value of torque to be transmitted to the transmission, the apparatus comprising: a flywheel connected with a driving shaft of the driving source; a supporting member unitarily rotating with the flywheel; a first plate having a sliding surface; a second plate having a sliding surface; a disc spring supported by the supporting member and biasing one of the first and second plates towards the other one thereof; a friction material sandwiched tightly between the sliding surface of the first plate and the sliding surface of the second plate; a damper mechanism connected to the friction material and transmitting the torque transmitted from the driving source to an input shaft of the transmission; and a cover member covering the sliding surfaces of the first and second plates from an exterior of the torque fluctuation absorbing apparatus, wherein the cover member covers an entire side surface of the first plate, which entire side surface is positioned at a side of the transmission, wherein the flywheel and the cover are in contact with each other in a sealing manner, and the input shaft and the cover are in contact with each other in a sealing manner.
