PURPOSE:To perform the maintenance inspection of a cleaning device efficiently by constituting attachably and detachably the upper side part of a case which forms a duct along a path from a brush to a filter and an air regulator plate. CONSTITUTION:The lid 50 of a filter taking-out opening provided to the case 4 is detached and a set screw 51 is loosened to take out the filter 37 together with a case 38. Then, a rotary catch 31 is drawn out and a groove 29 is detached from a pin 30 to remove a cover 26 from the case 4. Further, the rotary catch 25 of the air regulator plate 7 is drawn out and rotated upwardly around a shaft 20. The brush 3 or the inside surface of the air regulator plate 7 are cleaned. When a ''Teflon'' tape 8 stuck to the inside surface of the air regulator plate 7 should be replaced, a knob 24 is rotated to detach the shaft 20 engaged threadably with a screw hole 22, so that the air regulator plate 7 is taken out easily. Thus, the maintenance inspection is carried out efficiently. |
