主に連続気泡よりなるゴムまたは合成樹脂の発泡体が望
ましい。Then, a seamless sealing material 16 is arranged along the sealing rib 13. A suitable material for the sealing material 16 is a hydrophobic resin foam, which will be described later. In short, the sealing material 16 has a hard rubber tester "F" type of 95 or less, an elongation of 100% or more, and a tensile strength of 0.8.
b/d (all based on JIS K6402),
Rubber or synthetic resin foams consisting mainly of open cells with a density of 0.03 to 0.3 g/cm 3 are preferred.

ジング１０にセットすることができないか、セットでき
ても均一に皺が入らないため完全な止水が行なえない。Since the foam used for the sealing material 16 of the present invention is sometimes spread over the sealing portion during installation, the sealing material 16 expands and contracts. For this reason, the above characteristics are necessary, and conventional rubber foams cannot be used. That is, if the hardness is 95 or more, the elongation is 100% or less, and the density is 0.3 or more, it will not be possible to set it in the housing 10, or even if it can be set, the wrinkles will not be uniformly formed, so that it will not be possible to completely stop water.

することが可能となる。Mafko has a tensile strength of 0.8! If it is less than i, it is not preferable to attach the mating part because it may be damaged when it is set on the surface. Also,
If the density is less than 0.03, the fixation between the housing and the mating surface may loosen during long-term use, which may result in water leakage, which is undesirable. Moreover, the meaning that the sealing material 16 is "mainly composed of open cells" means that there are more open cells than closed cells, and as a result, even if the sealing material 16 is stretched or compressed during setting, the housing 16 is almost uniformly formed. It is possible to set it to .
上記シール材１６に使用されるゴムまたは合成樹脂の発

A hydrophobic agent such as asphalt can be added to it in post-treatment.
特に、疎水性ウレタン発泡体、エチレンプロピレン系ゴ

に沿わせる。This sealing material 16 is attached in an annular shape along the sealing rib 13, but before being attached to the housing 10, it has an elongated shape as shown in FIG. That is, the punched shape of the sealing material 16 is narrower in width and longer in length than the shape in the installed state, and a notch 17 is provided along the longitudinal direction at the center portion in the width direction. Therefore, in order to attach the sealing material 16 to the housing 10, pull the sealing material 16 with your fingers in the directions of arrows F and F' as shown in FIG. Seal rib 13 so that

定の位置に保持させることができるようになっている。The sealing material 16 has a hole 19 through which the fixture 12 is inserted.
Holes 20 into which the locking protrusions 14 are fitted are formed in advance by punching or the like, and by fitting the fixing tool 12 and the locking protrusions 14 into these holes 19 and 20, the sealing material 16 is inserted. It is possible to hold it in a predetermined position relative to the seal rib 13 in the expanded state.

皺はシール性能に影響を及ぼす程ではない。Note that in order to make it easier to spread the sealing material 16 into a rectangular shape, it is preferable to provide a small notch 21 inside the bent portion. Furthermore, in order to prevent both ends of the notch 17 from tearing, the notch 17 is
It is also effective to provide a continuous circular hole 22 at the end. Incidentally, when the sealing material 16 is spread, some wrinkles (see FIG. 3) are generated at each corner portion 16a, but these wrinkles are not large enough to affect the sealing performance.

周にわたってシールすることができる。After the sealing material 16 is attached to the housing 10 as described above, the housing 10 is fixed to the mating surface using the fixture 12. At this time, the seal material 16 is sandwiched between the seal rib 13 and the mounting surface and is suitably compressed and deformed, thereby making it possible to seal between the seal rib 13 and the mounting surface over the entire circumference.

４図の形状に容易に変形させることができる。Since the sealing material 16 is made of open-cell urethane foam, the sealing material 16 will not bulge out laterally even if it is compressed between the sealing rib 13 and the mounting surface, and will not bulge out to the side even if it becomes high temperature. The seal portion and the housing 10 will not be deformed due to gas expansion. Moreover, since it is open-celled, it is highly flexible and can be easily transformed from the punched shape shown in FIG. 2 to the shape shown in FIG. 4.

が実用上可能となった。このため従来品（第１２図参照
）のようにシール材を枠状に打抜かずにすむから大きな
打抜き孔が無くなり、材料歩留りが大幅に向上するもの
である。By providing the locking protrusion 14 on the housing 10 separately from the fixture 12, it is possible to prevent the sealing material 16 from returning to its original shape even if the sealing material 16 is spread out and used. Since the sealing material 16 can be fixed at the correct position along the line, it has become practically possible to use the sealing material 16 which is used by making a cut 17 and spreading it out as shown in FIG. Therefore, unlike the conventional product (see FIG. 12), it is not necessary to punch out the sealing material into a frame shape, eliminating the need for large punched holes and greatly improving the material yield.
なお本発明を実施するに当たってシール材１６は必ずし

開口部が形成されることになるが、従来品（矩形に打抜
いたもの）に比べれば材料歩留りがかなり向上する。In carrying out the present invention, the sealing material 16 does not necessarily need to be punched into the shape shown in FIG. 2. For example, it may be punched out in a rhombus or parallelogram shape (shape corresponding to FIG. 3). In this case, a narrow opening is formed along the longitudinal direction of the sealing material 16, but the material yield is considerably improved compared to a conventional product (one punched into a rectangular shape).

成しておく必要がない。Furthermore, as shown in FIG. 6, the sealing material 16 may be held more reliably by forming a fastener shape in which a detent pawl 24 is provided at the tip of the locking convex portion 14. Alternatively, the tip of the locking convex portion 14 may be made to have a sharply pointed shape so that the tip of the locking convex portion 14 is inserted into the sealing material 16. In this case, it is not necessary to form the holes 20 in advance.

明は省略する。12b are holes 19 formed in the sealing material 16, respectively.
By fitting the sealing material 16 into a predetermined position, the sealing material 16 is held in an expanded state. That is, in this embodiment, in addition to the locking convex portion 14, the fixture 12a,
12b also serves as a locking protrusion. In this case, the shape of the sealing material 16 is as shown in FIG. 8, and a notch 17 is formed along the length direction as in the embodiment described above. Other basic configurations and effects are the same as those of the previous embodiment, so common parts are given the same symbols and explanations will be omitted.
