That is, before the auto submerging occurs, the bag-like floating body 10 is inflated to add additional buoyancy to the marine hose 1, so that the marine hose line can be prevented from sinking to the bottom of the water. Therefore, the water pressure at the depth at which auto submerging does not occur is set as a preset water pressure for operating the injector 11.
