<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 seal an upper surface of the dust box body 8 is hooked on 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, and a U-shaped groove 62 for axially supporting a turning lever 15 is formed on a mounting part 8a on the upper surface of the dust box body 8. Thus, a shaft 15a of the turning lever 15 comes off the U-shaped groove 62 when the external force is applied to the buckle formed of the hooking part 14 and the turning lever 15. Therefore, the buckle formed of the hooking part 14 and the turning lever 15 is prevented from being broken, or the mounting part 8a on the upper surface of the dust box body 8 is prevented from being broken. <P>COPYRIGHT: (C)2013,JPO&INPIT |
