本考案は騒音防止およびシール性にすぐれたシ
ールワツシヤーに関する。[Detailed Description of the Invention] The present invention relates to a seal washer that has excellent noise prevention and sealing properties.

れ変形した弾性体2を長期間使用すると弾性体疲
労によるトルクダウンが発生して弾性力を弱め密
封性を極端に悪化させていたし再使用を全く受付
けないものとなるなど多くの欠点があつた。 Conventionally, various seal washers have been known for the purpose of preventing leakage of fixed parts of bolts and the like at locations where bolts and the like are assembled. Generally, as shown in Fig. 1, a reinforcing ring 1 having an inverted L-shape in cross section is used, and the inverted L-shaped reinforcing ring 1 is placed at the bottom of the reinforcing ring 1.
Sealing was attempted by providing a donut-shaped elastic body 2 that can be held by
The elastic body 2 causes a lateral flow from below the umbrella part 3 provided at the outer peripheral end of the holder, and not only does it not have sufficient adhesion force, but if the elastic body 2 that has been deformed by the lateral flow is used for a long period of time, torque down due to fatigue of the elastic body will occur. It had many drawbacks, such as weakening its elasticity and extremely poor sealing performance, making it completely unacceptable for reuse.
この様な欠点を解消すべく、該逆L字形状補強
環1の外周端に設けた傘部3を下部の弾性体2が
横流れしない範囲まで垂下させ横流れを防ぐ方法

形量が少な過ぎ高トルクを持つて締付けても該弾
性体2は十分な密着を行なわず密封性を向上させ

つてしまう。すなわち、該逆L字形状補強環1の
垂下する傘部3寸法及び中心から該傘部3までの
寸法は下部の弾性体2のトルクと変形量を左右し
密封性に大きく影響を及ぼすものであり自と限ら
れた形状となる。また昨今求められる防振、防音
対策に付いても弾性体2は充分なボリユームを必
要とし前記した横流れする欠点をさらに増加させ
る傾向にある。 In order to eliminate such drawbacks, a method has been implemented in which the umbrella part 3 provided at the outer peripheral end of the inverted L-shaped reinforcing ring 1 is suspended to a range where the lower elastic body 2 does not flow sideways, but this method prevents sideflow. Conversely, in this method, the amount of deformation of the elastic body 2 is too small, and even if the elastic body 2 is tightened with high torque, the elastic body 2 will not achieve sufficient adhesion and the sealing performance will not be improved, and it will not have any anti-vibration effect. It ends up. That is, the dimensions of the hanging umbrella part 3 of the inverted L-shaped reinforcing ring 1 and the dimension from the center to the umbrella part 3 affect the torque and deformation amount of the lower elastic body 2, and greatly affect the sealing performance. The shape is naturally limited. In addition, the elastic body 2 needs to have a sufficient volume in order to take measures against vibration and sound that are required these days, which tends to further increase the above-mentioned drawback of cross-flow.
本考案はこれらの欠点を除去し、シール性能に

しい。 To explain the present invention based on the drawings, Fig. 2,
And as shown in Figure 3, the head has a flat cross section,
Or, it is equipped with a metal reinforcing ring A having an umbrella part 3 at the outer peripheral end, the inner peripheral end, or both the inner and outer peripheral ends, and a sealing part 4 formed of an elastic body such as synthetic rubber or synthetic resin below the reinforcing ring A. The seal portion 4 has a convex seal ring 4a extending downward, and has a bolt insertion hole 5 at the center of the inner side, and has a flat shape on the body of the seal portion 4. It has a structure in which a washer B having a downward umbrella portion 6 at the inner circumferential end is inserted and integrated. In this structure, as shown in Fig. 2, a metal reinforcing ring A with an umbrella part 3 at the outer peripheral end is connected to a seal part 4 on the upper part of the washer B.
It is preferable that the inside diameter of the umbrella part 6 of the washer B inserted into the body of the seal part 4 is larger than the bolt insertion hole 5 of the seal part 4, so that the seal It is preferable to insert it at a position that does not reach the lower end of the protruding seal ring 4a and does not come into contact with the reinforcing ring A, since metal touch can be prevented.

可能とし、かつシールに最適な弾性を有する材料
を選択可能とする大きな効果を有している。 The seal washer of the present invention has a nut 7 attached to a support member 8 and screwed onto a bolt as shown in FIG.
etc., and the upper and lower parts of the seal part 4 come into pressure contact with the nut 7 and the support member 8, and exhibit a sealing effect. An attempt is made to cause excessive lateral flow outward from the umbrella portion 3. However, a rigid washer B inserted into the body of the seal part 4 disperses the amount of lateral flow of the elastic body, and since the washer B is integrated with the seal part 4, it comes into contact with the washer B of the seal part 4. Since the surface is completely deprived of mobility due to lateral flow and the periphery of the surface is also restrained, the amount of lateral flow is largely regulated to maintain sufficient elasticity and prevent excessive deformation. The effect of suppressing the amount of deformation of the seal portion 4 is to suppress the strain deformation and lateral flow failure of the elastic body, which is the material, and to greatly extend the life of the elastic body and to greatly improve the sealing performance, allowing repeated use. This has the great effect of making it possible to select a material with optimal elasticity for the seal.

裂・破損を防止するなどその作用効果は大きい。 In addition, in order to fix the support member 8, as shown in Fig. 1, the conventional seal washer does not have an effective fixing means in the radial direction other than the bolt that passes through the seal washer, so installation errors are likely to occur, resulting in incorrect installation. However, as shown in FIG. 3, the protruding seal ring 4a provided below the seal portion 4 and the downwardly directed umbrella portion 6 at the inner peripheral end of the washer B included therein
It fits into the mounting hole 9 of the support member 8 and guides it to the correct position where it can exert a large sealing force. Furthermore, since the umbrella part 6 of the washer B has a moderate rigidity, it suppresses excessive deformation of the elastic body located around it, and even if it receives excessive clamping pressure, the umbrella part 4a absorbs the pressure and prevents cracks and damage. Its effects are great.

向上させたものである。 In addition, the seal washer of the present invention has a sealing washer B having an umbrella part 6 on the inner peripheral edge inserted into the body of the sealing part 4, so that the sealing washer of the present invention is made of a material that maintains strong elasticity as described above. It suppresses vibration to a very small level due to its ease of use, dispersion of the amount of cross flow, and reduction of the amount of strain and deformation, and also greatly improves the soundproofing effect because it does not have any metal contact points.
