PROBLEM TO BE SOLVED: To provide an insertion machine capable of spreading an adhesive agent between a tip body and a tip cover evenly without irregularity and preventing the adhesive agent from entering into a place where it is prohibited.SOLUTION: An endoscope includes: a tip body 11 and a tip cover having a surface 22a at the tip body 11 side for covering the tip side of the tip body 11. A projection 12a is disposed on the tip surface of the tip body 11, the projection 12a projecting toward the tip side of the tip body 11, enclosing a hole 12 of the tip body 11, and including a tip surface 12b at the tip side of the tip body 11. An adhesive agent is regulated by the projection 12a when it contacts with the tip face 12b of the surface 22a of the tip cover, and is filled in a clearance IS1 which is formed between a surface of the tip body 11 side of the tip cover and the tip surface of the tip body 11.COPYRIGHT: (C)2015,JPO&INPIT【課題】先端部本体と先端部カバーとの間で接着剤をムラなくかつ均一に行き渡らせて、接着剤が侵入してはならない箇所への接着剤の侵入を防止することができる挿入機器を提供する。【解決手段】内視鏡は、先端部本体11と、先端部本体11の先端側を覆い、先端部本体11側に面部22aを有する先端部カバーとを有する。先端部本体11の先端面には、先端部本体11の先端側に突出し、先端部本体11の孔12を囲むように設けられ、かつ先端部本体11の先端側に先端面12bを有する突出部12aが設けられる。接着剤は、先端部カバーの面部22a先端面12bに密着しているときに、突出部12aにより規定され、先端部カバーの先端部本体11側の面と先端部本体11の先端面との間に形成された隙間IS1に充填される。【選択図】図8
