PROBLEM TO BE SOLVED: To enable an amount of air of an electric blower to be increased and improve a dust collecting power. SOLUTION: Front covers 6 covering a filter storing section 5 of an air cleaner are rotated around front cover rotating shafts 8 arranged at both right and left sides of the main body and then the front covers are opened or closed in both lateral rightward and leftward directions. With such an arrangement as above, it is possible to expose the surfaces of an air filter 4 directly to an external side, and further to pass surrounding atmosphere directly to the air filter 4, so that dusts of large size can be adhered to the air filter 4, an amount of air of the blower 2 can be increased, a dust collecting power can be improved and concurrently it is possible to make a passage of air flow under utilization of the front covers 6. |
