PURPOSE:To permit the miniaturization of diffuser by folding it when being transported by connecting each of a pair of upper and lower coupling bars provided with a gas diffuser to internal tube and external tube composing the main tube. CONSTITUTION:The main tube 1 consists of the cylindrical lower air tube 2 inserted into the cylindrical upper air tube 4. The coupling rods 5a and 5b connected at the connecting point 8 are attached to the coupling rod fittings 6 and 7 provided to the upper air tube 4 and the lower air tube 2. Also, the coupling rodes 9a and 9b are provided symmetrically with the coupling rodes 5a and 5b to form a link mechanism, and the collection tube 10 and a diffusing tube with a number of diffusing holes are provided projectionally to the connecting point 8. The collection tube 10 and the lower air tube 2 are connected with the flexible air supply hose. |
