In the previous embodiment, the hose reel 5 is the prime mover 3.
Although the rotation is not limited to this, for example, it may be rotated manually.

In the previous embodiment, the guide body 7 reciprocates, turns, and moves up and down with respect to the aircraft body 2, but the guide body 7 is not limited to this, and may be one that does not perform one or more of these movements, for example.

In the previous embodiment, the guide tube 8 was configured with two tubes, but the guide tube 8 is not limited to this, and may be configured with a single tube or three or more tubes, for example.

In the previous embodiment, the guide tube 8 is made of tubes made of different materials, but the guide tube 8 is not limited to this, and may be made of the same material, for example.

Although the guide tube 8 is a round tube in the previous embodiment, it is not limited to this, and may be a square tube, for example.

In the previous embodiment, the guide tube 8 was non-extendable and unbendable, but is not limited to this, and may be, for example, extendable or bendable.

In the previous embodiment, the guide tube 8 was configured using a tube, but the guide tube 8 is not limited to this, and may be configured, for example, by a semi-cylindrical so-called bucket.

In the previous embodiment, the guide tube 8 was a simple tube, but it is not limited to this. For example, a guide roller may be provided at the tip, a roller brush may be provided at the tip, or a fixed brush may be provided at the tip or inside. It is also possible to set one. If the hose is equipped with a brush, mud etc. attached to the hose can be removed.
