Further, since the ring-shaped wall portion 13 is provided around the lower surface 12 of the flange portion 11, garbage and the like hardly enter the nozzle 3. Further, since the tip of the corner 16 is formed to a position overlapping with the base end of the slit 9, the air moves smoothly from the slit 9 to the corner 16 of the rotating shaft 14. Further, since the slit 9 is provided in the mounting body 4,
The retaining portion 7 can be elastically deformed, and the attachment body 4 can be easily attached to the hole 2. Further, since the head 18 of the nozzle body 5 is formed by a curved surface, the resistance when the nozzle body 5 rotates is small. Further, since the nozzle body 5 is rotatably mounted on the mounting body 4 by the stop ring 15 as a mounting member, the nozzle 3 can be easily assembled. In addition, the gap between the upper surface 20 of the head 18 and the lower surface 12 of the flange portion 11 is in a direction substantially orthogonal to the air outlet 17, so that garbage and the like hardly enter the air outlet 17 from the outside.

FIG. 6 shows a second embodiment of the present invention, in which the same parts as those in the first embodiment are denoted by the same reference numerals, and the detailed description thereof will be omitted. 18 top view
20 are provided with irregularities 31. Therefore, when the rotating shaft 14 rotates, garbage, mycelia, and the like that have entered between the upper surface 20 of the head 18 and the lower surface 12 of the flange portion 11 are scraped off. The irregularities 31
May be formed on the lower surface 12 of the flange 11.

Or, since the unevenness 31 is provided on the lower surface 12 of the flange portion 11,
Garbage that has invaded between the upper surface 20 of the head portion 18 and the lower surface 12 of the flange portion 11 and propagated mycelia can also be scraped off.

FIG. 7 shows a third embodiment of the present invention. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. The lower surface 12 of the head 18 is formed in a tapered shape that expands downward, and the upper surface 20 of the head 18 is formed in a taper shape that expands downward, and the unevenness 31 is formed on the lower surface 12.

The gap between the upper surface 20 and the lower surface 18 is
Since it expands in a tapered shape, air can be easily blown out from the outlet 17 to the outside, and scraped garbage and the like can be discharged smoothly.

FIG. 8 shows a fourth embodiment of the present invention, in which the same parts as those in the above embodiments are attached and detailed description is omitted. In this embodiment, the rotating shaft 14 has a circular cross section. A plurality of ridges 16A, 16A, which are convex portions having a substantially triangular cross section, are provided around the rotation shaft 14. The ridges 16A are the lengths of the rotation shaft 14 excluding the small-diameter portion at the tip. A plurality of ridges 20A, 20A are formed radially about the rotation shaft 14 on the upper surface 20 of the head 18, and the ridges 20A are similar to the ridges 16A. It has a substantially triangular cross section. Further, a plurality of ridges 16B, 16B, which are convex portions having a substantially square cross section, are provided around the rotation shaft 14, and the ridges 16B extend in the length direction of the rotation shaft 14 excluding the small-diameter portion at the tip. It is formed over the entire length, and on the upper surface 20 of the head 18,
