A second means adopted by the present invention to solve the second problem is to use the zipper gasket as described above.
On both side surfaces of the tips of the zipper that are press-fitted between the mounting lip portions of the pair of gasket bodies, engage the tip corner portions of the mounting lip portions of the pair of gasket bodies, and The engagement ridges are provided to prevent the zipper from being retracted.

By adopting the first means, when the zipper is press-fitted between the pair of gasket bodies, the zipper is press-fitted between the mounting lip portions of the pair of gasket bodies in the zipper.
Partial counter press-fit side by increasing compressive deformation seal portion are integrally formed on both sides of each attachment Li of the pair of gasket members
The gap provided between the mounting lip portions is reliably closed by elastically contacting the side surface of the cap portion . Therefore, the sealability between the mounting lip portions of the pair of gasket bodies is improved.
Here, the zipper is composed of a two-piece body including a first zipper body press-fitted between the mounting lip portions of the pair of gasket bodies and a second zipper body press-fitted between the main body portions thereof. In this case, the seal portions can be integrally formed on each of the three surfaces of the first zipper body on the opposite press-fitting side and the end surface, and the seals between the mounting lip portions of the pair of gasket bodies can be formed integrally. The nature is further enhanced. In addition, the second zipper body is also attached to the surface of the second zipper body which is in close contact with the gasket body .
If the seal portion made of another material that is more easily compressed and deformed than the material of the body is integrally formed, the pair of gasket bodies and the second
The sealability with the zipper body is further enhanced. Furthermore,
If the outer surface shape of the cross section of the seal portion integrally formed with the first zipper body is formed into a wedge shape, the wedge effect facilitates the press-fitting of the first zipper body into the respective mounting lip portions of the pair of gasket bodies. Moreover, the sealing property of the portion is improved.

By adopting the second means, the zipper, which is press-fitted between the mounting lip portions of the pair of gasket bodies by the wind pressure or the like, has the front side (outside side) with respect to the gasket bodies.
It is possible to prevent a decrease in the sealing property of the press-fitted portion of the zipper because it does not move slightly.
