摘要:
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 have 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. Each segment piece is provided with at least one press-formed oil groove as one of the first and second oil grooves and at least one punched-out oil groove as the other one of the first and second oil grooves.
