ABSTRACT:
Lubricating oil is appropriately supplied to the lock-up clutch facing of a torque converter to thereby prevent heat generation during sliding engagement. Oil grooves are formed in that surface of the core plate 5 of the clutch to which the facing 3 is attached, whereby the oil is supplied from the back of the facing 3. The oil grooves preferably contain pressure-differential or centrifugal-force responsive valves.
