Abstract:
A friction plate for a wet-type multiplate clutch can include a core plate and friction linings bonded on opposite sides of the core plate, respectively. Each of the friction linings can include plural segment pieces bonded at angular intervals on a corresponding opposite side. The segment pieces can each include at least one first oil groove and at least one second oil groove. The first oil groove opens to a radially-inner side of its corresponding segment piece and has a closed end portion located in a radially-intermediate part of the corresponding segment piece. The second oil groove opens to a radially-outer side of the corresponding segment piece and has a closed end portion located in another radially-intermediate part of the corresponding segment piece. Adjacent ones of the segment pieces are provided, in radially-middle parts of opposing side walls thereof, with angularly-extending recessed portions, respectively.
