PROBLEM TO BE SOLVED: To solve the problem that when a flying body in which wheels having a protection function are provided to a flying body main body and which travels with its propulsion part inclined in a travelling direction is applied to the inspection of a ceiling, a wall, etc. of a deteriorated tunnel or a deteriorated bridge, it is impossible for the flying body to travel horizontally on a vertical wall since there is no lifting force vertically upward.SOLUTION: A flying body 1 having an axle 11 attached to a flying body main body 20 having a propulsion part 21 so that it is perpendicular to a travelling direction of wheels 12 in travelling on land includes a roll shaft 22 orthogonal to the axle 11, and a roll bearing 23 that rotatably engages with the roll shaft 22, either the roll shaft 22 or the roll bearing 23 being fixed to the flying body main body 20.SELECTED DRAWING: Figure 1 |
