LEVEL GAUGE STRUCTURE

To provide a level gauge structure which can alleviate a load when withdrawing a level gauge from a gauge hole.SOLUTION: A space 45 is formed between a circular column part 24 and an outside inclination face 43 of a gauge hole 41 in an attachment state. When a level gauge 6 is withdrawn from the gauge hole 41, a portion at a base end side is inclined from the circular column part 24 of the level gauge 6 up until a periphery of the column part 24 abuts on the outside inclination face 43. When a load in a direction in which the level gauge 6 is withdrawn from the gauge hole 41 is applied while a load for further inclining a grip part 14 of the level gauge 6 is applied to the grip part 14 after a peripheral face of the circular column part 24 abuts on the outside inclination face 43 of the gauge hole 41, an abutment portion between the circular column part 24 and the outside inclination face 43 of the gauge hole 41 functions as a pivot, instead of that entire peripheries of crest parts 21, 22 move while rubbing a cylindrical face 42 of the gauge hole 41, only a single side of the crest part 21 moves to a mouth edge side while rubbing the cylindrical face 42.SELECTED DRAWING: Figure 6 【課題】レベルゲージをゲージ穴から引き抜く際の荷重を軽減できる、レベルゲージ構造を提供する。【解決手段】装着状態において、円柱部２４とゲージ穴４１の外傾斜面４３との間には、空間４５がある。レベルゲージ６がゲージ穴４１から引き抜かれる際には、円柱部２４の周面が外傾斜面４３に当接するまで、レベルゲージ６の円柱部２４から基端側の部分が傾けられる。円柱部２４の周面がゲージ穴４１の外傾斜面４３に当接した後、レベルゲージ６の挟持部１４にその挟持部１４をさらに傾ける荷重が加えられながら、レベルゲージ６をゲージ穴４１から引き抜く方向の荷重が加えられると、円柱部２４とゲージ穴４１の外傾斜面４３との当接部位が支点となって、山部２１，２２の全周がゲージ穴４１の円筒状面４２に摺擦しつつ動くのではなく、山部２１の片側のみが円筒状面４２に摺擦しつつ口縁側に動く。【選択図】図６
