Zusammenfassung:	There is provided a cyclone separation device that can improve dust separation performance without increasing a size of the device, and prevent a backflow of dust collected in a dust collection chamber. To this end, the cyclone separation device includes: a swirl chamber (20) that swirls air containing dust along a side wall therein, and separates dust from the air containing dust; a first dust collection chamber (31) that communicates with an inside of the swirl chamber (20) through a first opening (28) formed in the side wall of the swirl chamber (20); a second dust collection chamber (32) that communicates with the inside of the swirl chamber (20) through a second opening (29) formed on a downstream side of the first opening (28)in the swirl chamber (20); a discharge pipe (33) that communicates with a discharge port (34) for discharging air in the swirl chamber (20); and a plurality of inlets (21, 25) that are provided on an upstream side of the first opening (28), and through which the air containing dust flows into the swirl chamber (20)
