<p>PURPOSE:To make a heat-resisting quality excellent and torque down small by conducting the coating of seal layers consisting of a compound containing base material fiber consisting of compressive organic fiber and compressive inorganic fiber that does not contain asbestos, on both sides of a metal plate coated beforehand with a heat-resisting bonding agent, in the case of a separate plate. CONSTITUTION:As for a base plate 10 constituting a separate plate 7, it is a metal plate 12 on whose sides of both which are coated beforehand with a heat-resisting bonding agent 11 seal layers 13 consisting of a compound containing a base material fiber consisting of both of compressive organic fiber and compressive inorganic fiber that does not contain asbestos, and a rubber material and rubber drugs and an inorganic filler, are coated. The check valve oil introducing hole 14a of the base plate 10 is of a cross section circular shape and is opened/closed by means of the spherical valve body of the check valve. As a result, the crack or loss or the like of a seal plate is not generated, and the inconvenience of an oil pressure circuit being stopped up is not generated, and leak between layers is not generated. Also, stress mitigation is small, and at the same time a heat-resisting quality is excellent.</p> |
