PROBLEM TO BE SOLVED: To provide a fluid supply appliance, regardless of a diameter of a distal end, capable of reliably and highly efficiently supplying fluid from a fluid supply port of a nozzle of an AW conduit (an air/water supply conduit) only to the inside of the AW conduit without damaging an observation window.SOLUTION: The fluid supply appliance includes: a tight fit part 50m formed at a first surface 50i and water-tightly and air-tightly fitted to a distal end face 3s in an insertion section of an endoscope so as to be elastically deformed a first opening 55i that is formed on the tight fit part 50m and, when the tight fit part 50m is tightly fitted to the distal end face 3s, encloses a fluid supply port 30k on the distal end face 3s a second opening 55t that is formed on a second surface 50t different from the first surface 50i and a conduit 55 that communicates the first opening 55i to the second opening 55t and to which a syringe 60 is connected via the second opening 55t.COPYRIGHT: (C)2015,JPO&INPIT【課題】先端部の径によらず、観察窓を傷付けることなくAW管路内のみにAW管路のノズルの流体供給口から確実かつ効率良く流体を供給することができる流体供給具を提供する。【解決手段】第1の面50iに形成されるとともに内視鏡の挿入部における先端面3sに水密気密に密着されて弾性変形する密着部50mと、密着部50mに形成されるとともに、密着部50mが先端面3sに密着された際、先端面3sにおける流体供給口30kを囲む第1の開口55iと、第1の面50iと異なる第2の面50tに形成された第2の開口55tと、第1の開口55iと第2の開口55tとを連通するとともに、第2の開口55tを介してシリンジ60が接続される管路55と、を具備する。【選択図】図5
