<P>PROBLEM TO BE SOLVED: To solve the problem that a cover part and a dust collecting container (dust box body) are immediately separated when a mounting engagement part is turned by mistake, and that the dust collecting container (dust box body) is dropped and broken on the floor in a conventional cyclone dust collecting device. <P>SOLUTION: The cover 11 constituted to close an upper surface of the dust box body 8 is hooked to a claw part 11a of the cover 11 by a buckle formed of a hooking part 14 and a turning lever 15 to be fastened and engaged with the dust box body 8. Even when the fastening and engagement of the hooking part 14 and the claw part 11a of the cover 11 is released by turning the turning lever 15, only the fastening and engagement of the hooking part 14 and the claw part 11a of the cover 11 is released at this time, and the hooking of the hooking part 14 and the claw part 11a is maintained. Thus, the dust box body 8 is prevented from being dropped and broken on the floor. <P>COPYRIGHT: (C)2013,JPO&INPIT |
