ABSTRACT:
A wet friction member which can maintain boundary lubrication by decreasing the thickness of oil film on a friction surface even when the sliding velocity increases. In a case where the friction surface of the friction member is in pressure contact with a mated member while rotating in a state of boundary lubrications a shearing resistance owing to viscosity of cooling oil is circumferentially applied to cooling oil in outer grooves in the friction surface. Since outer grooves extend from starting position of intermediate portions of the friction surface and terminate at the outer peripheral edge in a volute shape toward the direction of rotation, cooling oil in the outer grooves flows along the groove walls and is quickly discharged from opening portions at the outer peripheral edge.
