To eject fluid even to a distance with the expansion of an expansion tube structure and even to a corner part or narrow place of a room by detachably attaching the expansion tube structure at a jetting port of an aerosol jetting vessel and arranging a nozzle at the tip of the expansion tube structure.

The expansion tube structure is formed from a cylindrical body 4 composed of a nozzle 1, an intermediate joint cylindrical body 2 and an end part joint cylindrical body 3 and the end part of the cylindrical body 4 is connected to the jetting port of the aerosol jetting vessel. At this time, a rotatable joint 11 is arranged at the end part of the cylindrical body 4 and the expansion tube structure 1 is detachably attached to the jetting port 5. The intermediate joint cylinder 2 is used as a double cylindrical body 12 when the expansion tube structure 1 is shrunk and is used as a single cylindrical body at the time of expanding. Then the fluid is ejected even to a distance by expanding the expansion tube structure 1 and even to the corner part or narrow place because the nozzle 1 is arranged at the tip of the cylindrical body 4.
