Packing is used to create a seal by interposing the sealing part of two parts, but in the past, large packing with a complicated shape was used for relatively large sealing parts, such as oil pans used in automobile engines. With packing such as packing and valve cover packing, uniform tightening surface pressure cannot be obtained due to uneven tightening force when assembling, lack of precision of the cover member, etc. Especially when it is made by drawing a steel plate, it is difficult to obtain a uniform tightening surface pressure. If too much tightening pressure is applied, such as when using a cover member of It required great care and skill to obtain this, and was extremely poor in workability and stability.
以下、図面を参照しつつ詳述する。 A detailed description will be given below with reference to the drawings.
この様な欠点の対策として第４図で示す様な、

Protrusions 2 protruding lower than the thickness of the packing B are provided at multiple locations on the sealing surface 1 of the cover member A, and the protrusions 2
Packing B with a fitting hole 3 at the position where the
A device has been devised in which a cover member A is attached and tightened to prevent partial deformation of the cover member A due to over-tightening.

However, in the above structure, since the protrusion 2 is provided on the sealing surface 1 of the cover member A, the sealing surface 1 is easily distorted, resulting in a decrease in planar accuracy, and has serious drawbacks such as narrowing the sealing area of the packing B and reducing the sealing force.
本考案はこの様な欠点を除去し簡単な構造で過
大締付けを防ぎパツキングＢに均一な面圧を加え

を特徴としている。
As shown in Fig. 1, the present invention is a packing B1 made of an elastic material such as cork, synthetic rubber, or synthetic resin and having a plurality of mounting holes 4 for bolts, etc. It is characterized in that at least one small hole 5 is provided at the location, and a cylindrical object 6 having a height thinner than the thickness of the packing B1 and harder than the packing B1 is inserted into the small hole 5.

ので好ましいが特にこだわらない。 The height dimension of this cylindrical object 6 is packing B1
It is preferable that the thickness be formed to have the same thickness as the one that deforms under optimal compression to form a seal. on the other hand,
The small hole 5 into which the cylindrical object 6 is inserted does not matter whether it is penetrating or non-penetrating as long as it has a space into which the cylindrical object 6 can be inserted. It is preferable to use the vicinity of , as a large effect described later can be expected, but there is no particular restriction.
なお、該円筒状物６の材質は金属セラミツク・

ても外径寸法を容易に変化させない材質であるこ
とが求められる。 The material of the cylindrical object 6 is metal ceramic.
A hard material such as hard synthetic rubber or hard synthetic resin is preferable, and it is required that the material does not easily change the outer diameter even when the cover member A and the sealing member 8 are tightened.
この考案の要旨はパツキングＢ１の適正締付け

The gist of this invention is to determine the appropriate tightening dimensions of the packing B1 using a cylindrical object 6 having a certain height, and this structure makes it possible to apply the best possible tightening surface pressure to the packing B1. It is.
この様なパツキングＢ１に前記円筒状物６を取

を歪めることがない。 When attaching the cylindrical object 6 to such a packing B1 and tightening them, the cover member A first presses against the packing B1 and compresses it, as shown in FIG. invite At this time, the thickness of the packing B1 that provides an appropriate amount of tightening force is set in advance, so if the cylindrical object 6 with this thickness is present in the packing B1, the optimum tightening force can be obtained. When the cylindrical member 6 is tightened, both end surfaces of the cylindrical member 6 come into contact with the cover member A and the sealing member 8, preventing further tightening. At this time, if the cylindrical object 6 is located near the fastener 7, the tightening force acts directly on the cylindrical object 6, and the cover member A
will not distort.

付けによつてカバー部材Ａの局部を変形させたり
パツキングＢ１材料を老化させたりすることなく
平滑なシール面１を保ち最適な面圧をもつて長期
間安定的に強力な密封をなす。 The compressive surface pressure thus obtained maintains a smooth sealing surface 1 and has an optimum surface pressure without deforming the local part of the cover member A or aging the packing B1 material due to over-tightening as in the conventional case. It forms a stable and strong seal over a long period of time.
この様に厚み寸法の不変な挿入物を用いたこと

付け寸法を示しパツキングＢ１への緊締不備を一
掃した。 By using an insert whose thickness does not change in this way, it always shows the proper tightening dimension no matter what state it is attached to, eliminating the problem of insufficient tightening of the packing B1.

As explained above, the present invention has a simple structure that greatly improves tightening workability, and also prevents deformation of the cover member, obtains uniform tightening pressure, and prevents aging of the material due to local tightening fatigue. It is an ideal packer with many excellent effects.
