<P>PROBLEM TO BE SOLVED: To provide an effective technique in a dust collecting device with a dust collecting hood removably attached, with which easy attachment and detachment of the dust collecting hood can be achieved, and with which the dust collecting hood can be surely held onto a mounting position. <P>SOLUTION: The dust collecting device 210 includes a dust collecting device body 211, and a cylindrical dust collecting hood 221. A hood side mounting part 225 is formed in the dust collecting hood 221, and a body side mounting part 251 is formed in the dust collecting device body 211. The body side mounting part 251 can be relatively moved in a direction crossing the longitudinal axis direction of a tool tip between an engaged position to be engaged with the hood side mounting part 225 and a released position to be released from the engagement. In the engaged position, the body side mounting part 251 prevents the dust collecting hood 221 attached to the dust collecting device body 211 from becoming detached from the dust collecting device body 211 and holds this state, while in the released position, it allows the dust collecting hood 221 to be attached to and removed from the dust collecting device body 211. <P>COPYRIGHT: (C)2012,JPO&INPIT |
