A pressure plate 50 has a fitting portion being fitted into the boss portion 33 and having a second outer peripheral surface, and a pressure surface 60 surrounding the fitting portion. A plurality of friction plates are provided between the pressure-receiving surface 40 and the pressure surface 60. Oil is supplied into the boss portion 33. A first concave portion C1 that guides oil to the tip of the boss portion 33 is formed at an inner peripheral surface of the boss portion 33. A second concave portion C2 that guides oil to the pressure surface 60 is formed at a second outer peripheral surface to be opposite to the first concave portion C1. A third concave portion C3 that guides oil guided by the first and second concave portions C1, C2 to a friction plate located closest to the pressure surface 60 is formed at the pressure surface 60.
