Abstract

In a dust collector, an intake side surface on the intake portion side of a filter expands in a first direction, and extends in a direction including at least a component of a second direction. The housing of the dust collector includes a wall that defines an intake passage. The intake passage extends from the intake portion side to the filter side. One end of the intake passage is linked to the outside of the housing via the intake portion. Another end of the intake passage opposes a top surface side region of the intake side surface of the filter in a third direction perpendicular or substantially perpendicular to the first direction and the second direction. When viewed from the first direction, the top surface side region approaches the another end of the intake passage as it approaches the top surface side in the second direction.
