To provide an inspection tool which can inhibit leakage of a liquid effectively in an inspection in which a hole is made in a pipe to check the liquid in the pipe.SOLUTION: An inspection tool 1 includes: a body part 10 having a first contact surface 131 which contacts with a pipe 9 and a guide passage 100 which guides a drill blade 2 to the first contact surface 131; a sandwiching part 20 having a second contact surface 211 which contacts with the pipe 9 at a position facing the first contact surface 131 across the pipe 9; and a first holding part 30 which holds the sandwiching part 20 in a manner that the sandwiching part 20 can move relative to the body part 10 so as to adjust a distance between the first contact surface 131 and the second contact surface 211. The body part 10 includes: a seal member 122 which forms a part of the guide passage 100 and forms the first contact surface 131 on an end surface on which one end of the guide passage 100 opens; and a valve 110 provided in the middle of the guide passage 100. The drill blade 2 may be inserted into the valve 110 in an opening state.SELECTED DRAWING: Figure 7
【課題】配管に孔をあけて配管内の液体を確認する検査において、液体の漏出を効果的に抑制可能な検査具を提供する。【解決手段】検査具１は、配管９に当接する第１当接面１３１と、第１当接面１３１に向かってドリル刃２を案内する案内路１００とを持った本体部１０と、配管９を挟んで第１当接面１３１と対向する位置において配管９に当接する第２当接面２１１を持った挟み込み部２０と、第１当接面１３１と第２当接面２１１との間隔を調節できるように、挟み込み部２０を本体部１０に対して移動可能に保持する第１保持部３０とを有する。本体部１０は、案内路１００の一部を形成するとともに、案内路１００の一端が開口した端面において第１当接面１３１を形成するシール部材１２２と、案内路１００の途中に設けられたバルブ１１０とを含む。バルブ１１０は、開状態においてドリル刃２を挿通可能である。【選択図】図７
