Zusammenfassung:To provide an attaching/detaching jig capable of attaching/detaching a pump to/from a tank safely and easily.SOLUTION: An attaching/detaching jig 1 is used for attaching and detaching a pump 8 to be attached to a tank 7 with a lower part protruding from the tank 7. The tank 7 has a lock ring plate 9 provided at the lower part of the pump 8 protruding from the bottom part and for attaching/detaching the pump 8 with rotation. The lock ring plate 9 has: a body 2 in which a cutout part 91 is formed by cutting out a part thereof, and which is formed into a ring shape; and a hooking part 3 that is provided on the body 2, is inserted from below through the cutout part 91 when the pump 8 is attached or detached, and hooks the body 2 on the lock ring plate 9. An upper width W1 of the hooking part 3 is formed larger than a lower width W2.SELECTED DRAWING: Figure 3 【課題】タンクに対するポンプの脱着が安全かつ容易に行える脱着治具を提供すること。【解決手段】タンク7から下部を突出させた状態でタンク7に取り付けられるポンプ8の脱着に用いられる脱着治具1であって、タンク7は底部から突出するポンプ8の下部に設けられ回転することによりポンプ8の脱着を行うロックリングプレート9を有し、ロックリングプレート9はその一部を切り欠いた切欠き部91を形成し、リング状に形成される本体2と、本体2に設けられポンプ8の脱着時に切欠き部91に対し下側から挿通され、本体2をロックリングプレート9に掛け止める掛止部3とを備え、掛止部3の上部の幅W1が下部の幅W2より大きく形成されている。【選択図】図3
