PURPOSE:To perform inspection over a wide range through remote operation by fitting an extension arm which is operated by a telescopic tube mechanism having an observation device to a main body arm which is sent out and moves up and down, and right and left freely, raising the extension arm, and performing all operations at hand. CONSTITUTION:The inspecting device consists of the main body arm 7 which is sent out of a small-diameter hole 3 and the tension arm 10 operated by the extensible telescopic tube mechanism equipped with the observing device 9 atop. The main body arm 7 is inserted up to a room 2 until the extension arm 10 evades an obstacle 6. At this time, respective mechanisms for moving an operation mechanism part 14 upward and downward, and right and left are used so as to evade the obstacle 6. The extension arm 10 is raised gradually by using an extension arm elevating mechanism 15 after the obstacle is evaded. This operation is performed remotely from the side of an operation room 4 by using an elevation operation part 16. The environment is observed by using the observing device 9 during a series of those operation to confirm the positions of the obstacle and inspecting device body.
