果を一層高めることができる。According to the present invention, the wind is sucked from the main suction passage 22 of the suction port ring 21 between the inner circumference of the suction port 4 of the main body case 1 and the outer surface of the suction port ring 21 at the same time. The sub-suction channel 37 that rapidly sucks the wind is formed. Therefore, it is possible to suppress the generation of vortices between the rear side of the fan 14 and the diameter reduction side end portion of the suction port ring 21, and it is possible to reduce noise. In particular, the wind sucked into the auxiliary suction flow path 37 can smoothly flow through the curved path 35 along the arc surface 36 of the outer surface of the suction port ring 21 with less resistance, and the effect of suppressing vortex generation can be further enhanced.

The fan case 17 can also have a positioning and fixing function of restricting the rearward displacement. The narrow groove width W of the concave groove 27 formed between the suction port ring 21 and the outer ring 24
The forward flange 30b of the inlet grille 30 can be clamped and fixed in one part, and since the forward flange 30b is clamped and fixed in a point contact state over the entire circumference, even if the forward flange 30b is deformed in a wavy shape, The error can be absorbed, and it can be securely and easily mounted without being twisted during the mounting. In addition, the groove 27
The wide groove width W 2 can be used as a communication path between the rear outside of the suction port ring 21 and the through hole 26. Front facing flange 30b
Since the engaging claw 30c is caulked by using the through hole 26, it is not necessary to specially provide a hole for passing the engaging claw 30c, and the structure can be simplified accordingly.
