る。(Example) An example of the present invention will be described below based on the drawings. FIG. 1 shows an enlarged view of the main parts clearly showing the features of the rust-preventing washer 1 according to the present invention. The washer 1 is made of a synthetic resin sheet made of compressible and flexible material such as urethane foam. It is made of foam 2 (hereinafter referred to as foam). Inside this foam 2, there are many microcapsules 3.
are contained in the microcapsules 3, and a rust preventive agent 4 is encapsulated in each of the microcapsules 3. Microcapsule 3
is added to the material of the foam 2 in advance before molding the foam 2, and is contained in the foam 2 by the foam molding process, and the size is about several tens of microns to several hundred microns. The coating is made of a fine synthetic resin material such as epoxy, nylon, or polyethylene, and has a coating thickness that is capable of exuding the enclosed rust preventive agent 4 by crushing or spreading it under a predetermined pressure. It is equipped with Further, as the rust preventive agent 4, for example, a rust preventive oil, lubricating oil, wax, a mixture of these oils and fats, etc., are used which have a rust preventive effect and have a suitable viscosity.
前記ワツシヤー１は、通常のワツシヤーと同様

When the washer 1 is inserted and fastened, the washer 1
A part of the washer 1 is pressed against the seat surface 7 and compressed, and the microcapsules 3 contained in the washer 1 are crushed or spread as shown in FIG. 6, and the enclosed rust preventive agent 4 is released. be done. The released rust preventive agent 4 is impregnated into the foam 2, and a part of it oozes out from the foam and flows between the outer periphery of each fastened member 8, 11 and the screw shaft portion 10, and the rust preventive agent 4 is impregnated into the foam 2. Adheres to joint surfaces damaged during construction.

り効果的に流出する。 Therefore, the joint surface is rust-proofed with the rust-preventing agent 4, and since the rust-preventing agent 4 is impregnated into the compressed foam 2 of the washer 1, it will not gradually flow out. This allows the rust preventive effect to be maintained over a long period of time. Furthermore, on the outer periphery of the washer 1 which is not subjected to pressure, the microcapsules 3 remain in their original shape and the rust preventive agent 4 does not ooze out to the outside, so dust does not adhere to them, and the compressed foam 2 prevents water etc. from leaking from the outside. It acts as a sealant to prevent intrusion. Further, FIG. 7 shows another embodiment of the washer 12, in which a protrusion 13 is vertically provided on the lower surface of the washer 1 to fit into the attachment hole 9 of the one fastened member 8. The protrusion 13 is connected to the screw shaft 10.
The rust preventive agent 4 exuded under the pressure flows out into the joint more effectively.
尚、本願は前記実施例に限定されるものではな

ツシヤーの形状を方形その他の形状にすることが
できる。 Note that the present application is not limited to the above embodiments, and various modifications may be made within the scope of the gist. For example, the foam may be made of a synthetic resin material with compressible flexibility other than urethane foam. or the shape of the washer can be rectangular or other shapes.
（考案の効果）
前記した実施例でも明らかなとおり、本考案の
防錆ワツシヤーによると次のような効果を期得す
ることができる。(Effects of the invention) As is clear from the embodiments described above, the following effects can be achieved with the rust-preventing washer of the invention.
押圧を受けなければ防錆剤が放出されないの
で、使用以前の取扱いが容易である。 Since the rust preventive agent is not released unless it is pressed, it is easy to handle before use.
ねじ部品の締結時の押圧力で防錆処理が施こ
されるので、前記した従来形のように締結後に
格別に防錆処理を必要がなく工程を簡略化でき
る。 Since the rust prevention treatment is performed by the pressing force when the screw parts are fastened, there is no need for special rust prevention treatment after the screw parts are fastened, unlike the conventional type described above, and the process can be simplified.
防錆処理が必要が接合内部へ充分に浸透させ
ることができる。 Anti-corrosion treatment can be sufficiently permeated into the interior of the joint.
長期に亘つて防錆効果を維持できる。 The rust prevention effect can be maintained for a long period of time.
不必要な外部へ防錆剤を滲出させないので、
ほこりの付着等による汚れもない。 This prevents rust preventive from leaking out to the outside unnecessarily.
There is no dirt due to adhesion of dust, etc.
圧縮された発泡体がシール部材として機能
し、外部からの水等の侵入を阻止する。 The compressed foam functions as a sealing member and prevents water from entering from the outside.
