Abstract

PURPOSE:To easily detect the breakage of a belt simply by such a simple operation that a detection rod is just pressed by disposing the detection rod urged upward in such a manner as to bring the lower end into contact with the belt by pressure on a wain body case positioned above the belt. CONSTITUTION:A vacuum cleaner comprises a fan motor 11, a rotary brush 12 for scooping up dust and a power transmission belt 10 stretched between a rotating shaft 18 of the fan motor 11 and the rotary brush 12. Further, a detection rod 22 urged upward in such a manner as to bring the lower end into contact with the belt 1 by pressure is disposed on a main body case 7 positioned above the belt 10. Accordingly, the breakage of the belt can be simply detected by such a simple operation that the detection rod is just pressed.
