<P>PROBLEM TO BE SOLVED: To provide a technique which contributes to slip-off prevention of a dust collecting hose disposed for dust transfer, in an impact tool having a dust collecting device which sucks and collects dust generated during a working operation. <P>SOLUTION: The impact tool includes the dust collecting device 150 which is mounted on a tool body 103 and includes a dust suction port 157b for sucking the dust generated during the working operation by means of a tool bit 119 and a dust transfer passage 157a for transferring the dust sucked through the dust suction port 157b. The dust collecting device 150 further includes: the dust collecting hose 161 having a bellows-like part 161a causing the dust flowing through the dust transfer passage 157a to flow to the outside of the dust transfer passage 157a; a hose attaching region 159 to which the dust collecting hose 161 is attached so as to be communicated with the dust transfer passage 157a; and a dust collecting hose slip-off preventing member 163 which is disposed in the hose mounting region 159, is engaged with the bellows-like part 161a and, thereby, prevents the dust collecting hose 161 attached to the hose mounting region 159 from slipping off from the hose mounting region 159. <P>COPYRIGHT: (C)2012,JPO&INPIT |
