<p>A dust collecting device includes a first centrifugally separating part 41 for centrifugally separating dust and second centrifugally separating parts which communicate with the first centrifugally separating part 41 and centrifugally separate dust finer than that separated by the first centrifugally separating part 41. The first centrifugally separating part 41 has a case body 51 capable of housing dust and a cylindrical turning part 52 which is arranged in the case body 51 and turns air containing dust between the turning part and the case body 51. The turning part 52 includes, at its circumference, circumferential openings 65 communicating with the second centrifugally separating parts and, at its end, an end opening 74 communicating with the second centrifugally separating parts. The first centrifugally separating part 41 has a compression filter 54 provided on the end opening 74.</p> |
