PURPOSE:To shorten a moving time by enhancing passing property and operability in passing a bent part, by such constitution that a pair of moving trucks moving along a guide rail are connected by a movable connecting member and the leading end part of the arm pivotally mounted to each moving truck is pivotally mounted through one sensor. CONSTITUTION:A moving inspection apparatus 200 is constituted of a pair of trucks 201a, 201b, a flexible body 205 and flexible arms 203a, 203b and, when passed through a bent part, the arms 203a, 203b are bent corresponding to the bent part and the own wt. of the moving truck 201b is supported by the flexible body 205. When the moving truck 201a moves to the direction shown by the arrow X by a chain 107, a drum 204 is rotated at a speed two times of the truck moving speed and the flexible body 205 is wound up to move a sensor 110 along a welding part 101a in a circumferential direction to the direction shown by the arrow Y while rotating the arms 203a, 203b from a solid line position toward a two-dot broken line position. |
