【考案の詳細な説明】〔考案の目的〕（産業上の利用分野）本考案は継手本体とチユーブとの係合の適否を
検査する隙間ゲージに関する。[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a feeler gauge for inspecting the suitability of engagement between a joint body and a tube.

ら使用されている。(Prior Art) Fig. 4 is a diagram showing a state in which a tube is engaged with a bite joint, in which the end of the tube 21 is inserted into the joint body 20, the nut 22 is tightened, and the nut 22 is screwed in the direction of the arrow. As a result, the sleeve 23 interposed between the tube 21 and the joint body 20 is pressed and deformed to bite into the tube 21, thereby firmly engaging the tube 21 with the joint body 20 to prevent it from falling out. In addition to the above-mentioned bite-in joints, compression joints in which two sleeves are interposed have also been used.

あると判断するようにしている。 By the way, in the above joint, if the nut 22 is not tightened sufficiently, there is a risk that the tube 21 may come off. Therefore, as a jig to check whether the tightening is sufficient, a fork-type feeler gauge is conventionally inserted into the gap l between the nut 22 and the joint body 20, and if the gauge enters the gap l, it is determined that the tightening is insufficient. I try to do that.

（考案が解決しようとする問題点）上述したフオーク型隙間ゲージによれば、簡単

が、チユーブの太さに応じて継手の径も異なり、
且つ適正な締付け力も異なってくる。このため、
各種の継手の締付け具合を検査するには多数の隙
間ゲージを用意しなければならない。(Problem to be solved by the invention) According to the above-mentioned fork-type feeler gauge, it is possible to judge the quality of tightening with a simple operation, but the diameter of the joint varies depending on the thickness of the tube.
Moreover, the appropriate tightening force also differs. For this reason,
In order to inspect the tightness of various joints, it is necessary to prepare a large number of feeler gauges.

[Structure of the idea]

（問題点を解決するための手段）上記問題点を解決すべく本考案は、二股状のフ
オーク型隙間ゲージの二股部の間隔を先端から他
端へ向つて段階的に狭くするとともに、先端から
他端へ向つて段階的に厚みが大きくなるようにし
た。 (Means for Solving the Problems) In order to solve the above problems, the present invention gradually narrows the interval between the fork portions of the fork-shaped feeler gauge from one end to the other end, and The thickness was made to gradually increase toward the other end.

（作用）フオーク型隙間ゲージの二股部の間隔が段階的
に狭くなるとともに厚みも順次増すため１本の隙
間ゲージにより、多数本の隙間ゲージを用意した
のと同じことになる。(Function) Since the distance between the forked parts of the fork-type feeler gauge gradually narrows and the thickness gradually increases, using one feeler gauge is the same as preparing a large number of feeler gauges.

（実施例）以下に本考案の実施例を添付図面に基づいて説
明する。(Example) An example of the present invention will be described below based on the accompanying drawings.

むことにより検査する。 FIG. 1 is a perspective view showing the use of the fork-type feeler gauge according to the present invention, in which two tubes 1, 1 have their ends inserted into the joint body 2, and the nuts 3,
They are joined by tightening 3. Then, the strength of the engagement between the joint body 2 and the tube 1, that is, the quality of the tightening of the nut 3, is inspected by inserting a fork type clearance gauge 4 into the gap between the joint body 2 and the nut 3.

と、t₁＜t₂＜t₃となるようにしている。 As shown in FIGS. 2A and 2B, the gap gauge 4 consists of left and right bifurcated portions 5, 5, and the interval between the bifurcated portions 5, 5 is gradually narrowed from one end to the other end. In other words, if the distance between the tips of the forked portions 5, 5 is d ₁ , the distance at the middle is _d2 , and the distance at the rear is _d3 , then _d1 > d ₂ > d ₃ , and the distance between the forked portions 5, 5 The thickness gradually increases from the tip to the other end. In other words, if the thickness of the fork portions 5, ₅ at the tip is t1, the thickness at the middle is _t2 , and the thickness at the rear is _t3 , then _t1 < _t2 < _t3 .

A gap gauge 6 having different combinations of spacing and thickness is integrally provided on the other end side. That is, the gap gauge 6 added to the gap gauge 4
The bifurcated parts 7, 7 have two types of intervals _d4 , _d5 , and the thickness of the tip part is _t4 . And said d ₁ ,
The relationship between d ₂ , d ₃ , t ₁ , t ₂ , and t ₃ is d ₁ = d ₄ > d ₂ = d ₅ >
d ₃ , t ₁ < t ₂ = t ₄ < t ₃ .

である。 As explained above, according to the fork-type feeler gauge according to the present invention, since the spacing and thickness of the bifurcated parts are varied in stages, it is possible to judge whether or not the tightening of many types of joints is good or bad with a single feeler gauge. It's convenient.
