PROBLEM TO BE SOLVED: To provide an inspection jig, an inspection device and an inspection method that can suppress damage to a ring member.SOLUTION: An inspection jig comprises: a jig body 32 that has an insertion part 41 to be inserted into a target component 21, has an internal passage 48, has peripheral grooves 51 to 53 to be provided on an outer peripheral side of the insertion part 41, has communication holes 55 to 57 for communicating the internal passage 48 with the peripheral grooves 51 to 53 and has discharge holes 61 and 62 provided closer to an insertion direction tip than the peripheral grooves 51 and 53 of the insertion part 41 so as to communicate the internal passage 48 with the outside of the insertion part 41; and elastic ring members 33 to 35 that are fitted in the peripheral grooves 51 to 53. The inspection jig is formed so that each outer diameter of the ring members 33 to 35 becomes larger than that before application of fluid pressure and becomes larger than an outer diameter of the insertion part 41 when the insertion part 41 is inserted into the target component 21 and the fluid pressure is applied.SELECTED DRAWING: Figure 1
【課題】リング部材の損傷を抑制することができる検査治具、検査装置および検査方法の提供。【解決手段】対象部品21に挿入される挿入部41と、内部通路48と、挿入部41の外周側に設けられる周溝51〜53と、内部通路48と周溝51〜53とを連通する連通孔55〜57と、挿入部41の周溝51,53よりも挿入方向先端側に設けられて内部通路48を挿入部41の外側に連通する吐出孔61,62と、を有する治具本体32と、周溝51〜53に嵌合される弾性体のリング部材33〜35と、を備え、挿入部41を対象部品21に挿入して液圧をかけた場合に、リング部材33〜35の外径は液圧をかける前よりも大きくなり且つ挿入部41の外径よりも大きくなるように形成される。【選択図】図1
