ABSTRACT:
A friction plate for a wet-type multiplate clutch is provided with a core plate and friction linings bonded on opposite sides of the core plate, respectively. Each of the friction linings is composed of plural segment pieces each having at least one first oil groove and at least one second oil groove. The first oil groove opens to a radially-inner side of the friction plate and has a closed end portion located in a radially-intermediate part of the friction lining, and the second oil groove opens to a radially-outer side of the friction plate and has a closed end portion located in another radially-intermediate part of the friction lining. The second oil groove has a shape that its angular width becomes narrower from its open end portion toward its closed end portion thereof, and at the open end portion, the angular width of the second oil groove is reduced. The first oil groove may be provided with an oil pocket at its closed end portion.
