PROBLEM TO BE SOLVED: To provide an endoscope tube connecting section securing cleanness of the inside of a tube by preventing protrusion of a bonding material to the inside of the tube.SOLUTION: A connecting section 50 is formed by covering one end 53 of the tube 51 that is configured to contract in the radial direction, over a pipe 61 and bonding them with the bonding material 71. The connecting section 50 includes an accumulation portion 91 in which the bonding material 71 is accumulated. When the accumulation portion 91 is disposed on the outer peripheral face 63b of the pipe 61, the accumulation portion 91 is disposed on the outer peripheral face 63b of the pipe 61 excluding the outer peripheral edge part 63c of the pipe 61.COPYRIGHT: (C)2013,JPO&INPIT【課題】 接合材がチューブの内部へはみ出すことを防止でき、チューブの内部の清潔性を確保できる内視鏡配管接続部を提供すること。【解決手段】 接続部50は、径方向に収縮するチューブ51の一端部53をパイプ61に被覆して接合材71で接合する。接続部50は、接合材71が溜まる溜まり部91を有している。溜まり部91がパイプ61の外周面63bに配設される場合には、溜まり部91は、パイプ61の外周縁部63cを除くパイプ61の外周面63bに配設される。【選択図】 図2A
