It travels straight by inertial force and is sent to the coarse dust collection chamber 66. Dust (coarse dust) flowing into the coarse dust collection chamber 66 from the coarse dust discharge port 78 is accumulated in the coarse dust collection chamber 66. On the other hand, among the dust-containing air flowing from the first part 76 to the first separation part 65, fine dust and air having a relatively small mass spread radially from the outlet of the first part 76 to form the second ring 77. After passing through the first mesh filter 82 provided on the side surface, it flows into the filter chamber 67 via the relay air passage 85. Along with the dust (coarse dust) flowing into the coarse dust collection chamber 66 from the coarse dust discharge port 78, a part of the air also flows into the coarse dust collection chamber 66. The air flowing into the coarse dust collection chamber 66 passes through the second mesh filter 87 and flows into the filter chamber 67. Fine dust contained in air (air containing fine dust) flowing into the filter chamber 67 through the first mesh filter 82 or the second mesh filter 87 is filtered and separated by the filter unit 53, and Be captured. The clean air passing through the filter unit 53 is sucked into the electric blower 8 via the communication air passage 63.
