Abstract
In a wet-type multi-plate clutch comprising an externally-toothed plate and an internally-toothed plate each of which is formed by adhering a friction material on a core plate and in which torque is transmitted by engaging the externally-toothed plate and the internally-toothed plate, the friction materials are adhered on opposed surfaces of the externally-toothed plate and the internally-toothed plate which are opposed to each other.
