An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a gasket according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view of a gasket according to one embodiment of the present invention in use at a stepped portion.

In FIGS. 1 and 2, the gasket 11 is
It has a leg portion 12 that is press-fitted between the joints G, a sealing portion 13 that spreads on both surface sides of the joint, and a shaft portion 14 that connects the leg portion 12 and the sealing portion 13.

The sealing portion 13 comprises an elastic body 15 and a metal wedge body 16. The main body 15 extends on the surface S side of both edges of the joint, has contact projections 17 on both sides, and has a groove 1 for press-fitting the wedge body 15 in the center.
8 The contact protruding pieces 17 are slightly thin, and are inclined so as to diagonally descend toward the surfaces S of both edges of the joint in a state of being attached to the joint G. Also, a step portion 19 that receives both side edges of the wedge body 16 described below is provided on the upper surface of the main body 15.
It has.

The wedge body 16 includes an umbrella section 20 and a wedge section 2.
And 1. The umbrella portion 20 extends along the surface of the main body 15, and both side edges end inside the edge of the main body 15. The wedge portion 21 extends downward from the center of the umbrella portion 20 and pushes the groove 18 left and right while being pressed into the groove 18 of the main body 15, and cooperates with the umbrella portion 20 to form the main body 15. The contact projection 17 is bent downward and pushed down.

In the joint gasket 11 of this embodiment, if there is no step on both edges of the joint, the wedge body 16
And the main body 15 is extended and pressed against the surfaces S of both edges. If a step occurs at both edges of the joint, the contact protrusion 17 is flexibly deformed to absorb the step, and the contact protrusion 17
Only comes into contact with the joint surface S. Therefore, large deformation of the entire gasket does not occur. Therefore,
Does not significantly impair appearance. In addition, the rigidity of the metal wedge body 16 prevents undulation due to small bending in the extension direction of the gasket 11, keeps the joints straight in appearance and improves appearance.
