Abstract:
PROBLEM TO BE SOLVED: To provide a laminated gasket which is adapted to a box body having a wide interval between housings to be joined, and can respond to a requirement of high followability to "surface opening".SOLUTION: A laminated gasket is composed of an upper-stage gasket 3, a middle-stage gasket 4 and a lower-stage gasket 5. In the gasket constituting the upper-stage gasket 3 and the lower-stage gasket 5, one group of positioning holes which oppose each other is formed at a periphery of the gasket, and in the gasket constituting the middle-stage gasket 4, two groups of positioning holes which oppose each other are formed at a periphery of the gasket. The opposing positioning holes of the upper-stage gasket 3 in one group and the opposing positioning holes of the lower-stage gasket 5 in one group differ from each other in phases, the positioning hole in one group of the middle stage gasket 4 corresponds to the poisoning hole of the upper-stage gasket 3, and the positioning hole in the other group corresponds to the positioning hole of the lower-stage gasket 5. The middle-stage gasket, the upper-stage gasket and the lower-stage gasket are fixed into the corresponding positioning holes by pins 8, 9 and 10.SELECTED DRAWING: Figure 3
