In order to achieve simultaneous disposal of fine dust that is separated by a second centrifugal separation section and coarse dust that is separated by a first centrifugal separation section using a simple structure, this dust collection device (100) comprises a dust collection cap (111) that is partitioned into a first dust collection chamber (111A) that collects coarse dust and a second dust collection chamber (111B) that collects fine dust, and one part of a wall surface that constitutes the second dust collection chamber (111B) is the outer circumferential surface (111C) of the first dust collection chamber (111A). |
