Abstract
Disclosed is a lock-up clutch mechanism which is simple in construction but can increase the rigidity and the heat capacity of the lock-up piston, can lighten the lock-up piston, can suppress the temperature of a second sliding surface from being raised to enhance the heat resistance of the second friction member. The lock-up clutch mechanism is provided with a connecting member for connecting a lock-up piston with a center plate of a damper mechanism. The connecting member has a drum portion extending in the axial direction of an input shaft and splined to the radially outer peripheral portion of a center plate, and a hollow disc plate portion integrally connected with the axial end portion of the drum portion and radially inwardly extending from the axial end portion of the drum portion. The hollow disc plate portion is further in face-to-face relationship with the sliding surface of the lock-up piston across the lock-up piston.
