Abstract: A box-type dust collector includes a suction unit that includes a brushless motor and an air blowing fan, a battery mount portion, to which a battery pack that serves as a power source is mountable, a suction port that suctions outside air through rotation of the air blowing fan, and a filter that separates dust from the outside air which is suctioned from the suction port. The bottom surface of a tank serves as a surface for stationary placement. A handle for carriage is provided at a position directly over the center of gravity of the entire box-type dust collector with the battery pack mounted to the battery mount portion. Coupling portions to be coupled to both ends of a shoulder belt are provided at front and rear positions that are point-symmetric about the center of gravity as viewed in plan.
