Claims

[Scope of utility model registration request]

In a working traveling aircraft in which at least one of the left and right traveling bodies provided on the aircraft body can be moved in the left-right direction to adjust the distance between tracks between the traveling bodies, an extension and contraction mechanism that transmits power from the body side to the traveling body side. A flexible power transmission shaft is covered by a plurality of cylindrical bodies that are fitted and assembled in a slidable and telescopic manner, and a seal body that slides into contact with the inner circumference of the outer-fitting side cylindrical body and the outer circumferential surface of the inner-fitting-side cylindrical body. is fixed, and the seal body is further formed with an extension portion extending in the direction of contraction of the cylinder with a slight gap from the outer circumferential surface of the inner-fitting side cylinder. Seal structure of distance adjustment device.
