PROBLEM TO BE SOLVED: To provide an injection cylinder fitting structure of a tank which can prevent a seal packing from dropping and being turned up when fitting an injection cylinder to a tank main body via the seal packing and can easily fit the injection cylinder to the tank main body.SOLUTION: In relation to an injection cylinder fitting structure of a tank 1 for fitting an injection cylinder 3 to a tank main body 2 and, at the same time, sealing between the tank main body and the injection cylinder, an insertion hole 6a for inserting the injection cylinder 3 is formed on the tank main body 2, a flange 7 which seats on a seat surface 8 outside the insertion hole 6a when being inserted to the insertion hole 6a is formed on the injection cylinder 3, and a seal packing 5 for sealing between the tank main body 2 and the injection cylinder 3 includes an annular seal part 11 which is arranged on the seat surface 8 and seals between the flange 7 and the seating surface 8, a fitting seal part 20 which is integrally formed with the annular seal part 11 and is fitted to an outer circumference of the injection cylinder 3 and a tongue piece part 26 which is formed on the annular seal part 11 so as to be extended to the radial direction outer side and expands an inner diameter of the fitting seal part 20.SELECTED DRAWING: Figure 4 【課題】タンク本体に注入筒をシールパッキンを介して装着するとき、シールパッキンの落ち込みやめくれを防ぐことができ、タンク本体に注入筒を容易に装着できるタンクの注入筒取付構造を提供する。【解決手段】タンク本体２に注入筒３を装着すると共にその間をシールするためのタンク１の注入筒取付構造であって、タンク本体２に、注入筒３を挿入する挿入孔６ａを形成し、注入筒３に、挿入孔６ａに挿入したとき挿入孔６ａより外周の座面８に着座するフランジ７を形成し、タンク本体２及び注入筒３間をシールするためのシールパッキン５が、座面８上に配置されフランジ７及び座面８間をシールするための円環状シール部１１と、円環状シール部１１と一体に形成され注入筒３の外周に嵌合するための嵌合シール部２０と、円環状シール部１１に径方向外方に延びて形成され、嵌合シール部２０の内径を広げるための舌片部２６とを備えるものである。【選択図】図４
