The operation request unit includes a switching piece that is displaced between an on position for activating the dust collection mechanism and an off position for stopping the dust collection mechanism. The switching piece: is disposed next to the inflow port in a position not overlapping the inflow port and in the opening direction of the inflow port; is displaced from the off position to the on position when acted upon by external force; and returns from the on position to the off position in response to elimination of the external force.
