Since the fluid is press-fitted from the inside to expand the cover 3 inward, the cross-sectional area of the conduit 2 is changed so that the air volume is continuously adjusted. Since it does not hinder the flow of air, the ventilation resistance can be reduced, and the flow passage is located in the center of the pipe 2, so that the air distribution is improved. Moreover, since the number of components is small, the structure can be simplified.

同様な作用及び効果が得られる。Further, as shown in FIG. 6, the cross section of the pipe line may be rectangular, and in this case, the injection pipe 5 is required for each rectangular surface, but from each injection pipe 5 to the pipe line 2. By press-fitting the fluid between the airtight cover 3 and the airtight cover 3, the airtight cover 3 immediately below each injection tube 5 swells inward as shown in FIG.
The airtight cover 3 at the corners of the rectangle is not deformed so much, and the same operation and effect as described above can be obtained.
