PROBLEM TO BE SOLVED: To provide an in-borehole inspection device comprising a self-travel device which can stably travel in a hole of a borehole.SOLUTION: An in-borehole inspection device comprises: a self-travel device 100 which travels in a hole of a borehole; and a control device 200 which controls travel of the self-travel device 100. The self-travel device 100 comprises: inspection devices (camera part 2, transmission device 70a, reception device 70b) for inspecting inside of a hole; a travel vehicle 1; arms (first arm 6a, second arm 6b) whose one end sides are connected to the travel vehicle 1 (chassis 1b) through a hinge part; upper hole wall drive wheels (first upper hole wall drive wheel 3, second upper hole wall drive wheel 4) disposed on the other end sides of the arms and contact the upper hole wall; and moment application means for applying a moment in a direction where the travel vehicle 1 and the upper hole wall drive wheels are separated, to the arms.SELECTED DRAWING: Figure 1

    【課題】ボーリング孔の孔内を安定して走行することができる自走装置を備えた孔内調査装置を提供する。【解決手段】ボーリング孔の孔内を走行する自走装置100と、自走装置100の走行を制御する制御装置200とを有する孔内調査装置であって、自走装置100は、孔内を調査する調査装置(カメラ部2、発信装置70a、受信装置70b)と、走行車両1と、一端側がヒンジ部を介して走行車両1(シャーシ1b)に接続されたアーム(第1アーム6a、第2アーム6b)と、アームの他端側に設けられ、上孔壁に当接する上孔壁駆動輪(第1上孔壁駆動輪3、第2上孔壁駆動輪4)と、アームに対して、走行車両1と上孔壁駆動輪とが離れる方向のモーメントを付与するモーメント付与手段とを備えている。【選択図】図1
