PURPOSE:To improve the assembly performance and improve the heat resistance, oil resistance, and rupture resistance by punching out holes separately on a separating plate and a gasket coated with adhesive and integrally attaching the both. CONSTITUTION:A separating plate 12 and a gasket 10 are attached integrally by an adhesive 11. Therefore, the heat resistance, oil resistance, and the rupture resistance are improved, and the sealing performance is improved, and the erroneous operation of a hydraulic controller and generation of valve stick are prevented. Further, the need of confirming the obverse and reverse surfaces of the gasket 10 and positioning is avoided, and bending of the gasket 10 is prevented and assembly performance can be improved, Further, since the separat ing plate 12 and the gasket 10 are punched out separately, the need of the process for increasing the diameter of a gasket hole corresponding to an orifice in the prior art is avoided, and the punching-out precision can be improved. |
