ABSTRACT:
Oil is introduced into gaps between divided pieces forming a friction facing to enhance sealability of working oil of a lockup clutch upon operation of the lockup clutch to enhance sliding characteristics and durability of the friction facing. The friction facing 30 is included in the lockup clutch 2 of a torque convertor 1, and includes a plurality of divided pieces divided in the circumferential direction. Gaps that are out of fluid communication from the outer circumferential side to the inner circumferential side are provided between the divided pieces with the lockup clutch in an engaged state.
