Abstract
A friction plate is formed of a core plate and friction linings bonded on opposite surfaces of the friction plate, respectively. To permit cooling of each friction lining from a side of its associated surface of the core plate, the friction plate is provided, for example, with oilways or grooves arranged on the associated surface of the core plate, adhesive-free parts existing on he associated surface of the core plate, or loosely-packed portions existing in the friction lining such that lube oil is also facilitated to enter each friction lining from the side of the associated surface of the core plate.
