PROBLEM TO BE SOLVED: To provide a structure inspection device requiring little time and labor to handle, which is capable of reducing vibrations transmitted to an inspection device, and capable of being efficiently operated while being hardly affected by existing equipment on a structure, while also hardly affecting the functions of the structure.SOLUTION: A structure inspection device 1 is provided on each of both ends of an undercarriage 15, with four wheels 16, which travel along a handrail 13 of an inspection passage 3. The undercarriage 15 thereon comprises: a rotary support 17 which rotates about a rotary shaft while extending in a vertical direction; a telescopic swing arm 20 connected to the top end of the rotary support 17 via a swinging joint 19; a visible light camera 23 mounted on one end of the swing arm 20 via a gimbal device 22; and a counter weight 25 mounted on the other end of the swing arm 20. An interval between the wheels 16 on the end part in the traveling direction and the wheels 16 which are adjacent to said wheels 16 is determined so as to be adjustable to a length longer than a length of an interrupt part on the handrail 13.SELECTED DRAWING: Figure 2 【課題】取り扱いの手間が少なく、点検装置に与える振動を低減でき、構造物に存在する設備から受ける影響が少なくて効率的に動作でき、また、構造物の機能に与える影響の少ない構造物点検装置を提供する。【解決手段】構造物点検装置１は、車台１５の両側に、検査路３の手摺１３に沿って走行する車輪１６を４個ずつ備える。車台１５の上に、鉛直方向に延在すると共に軸回りに回転する回転支柱１７と、回転支柱１７の上端に揺動関節１９を介して連結された伸縮可能な揺動アーム２０と、揺動アーム２０の一端にジンバル装置２２を介して取り付けられた可視光カメラ２３と、揺動アーム２０の他端に取り付けられたカウンターウェイト２５を有する。進行方向の端部の車輪１６と、この車輪１６と隣り合う車輪１６との間の間隔が、手摺１３が有する途切れ部の長さよりも大きく設定可能に形成されている。【選択図】図２
