(2) The propulsion device according to claim 1 of the utility model registration claim, wherein an elastic material that contracts when compressed is interposed between at least one end of the rigid protection tube and the end surface of the hume tube body opposite to the one end. Flexible Huyume canal. (3) Utility model registration claim 1, in which a thin second protective tube is interposed between the rigid protective tube and the flexible body and has a second weakened portion that cracks due to bending stress and extends in the axial direction.
The flexible hume tube for propulsion according to item 1 or 2.
