PROBLEM TO BE SOLVED: To provide an improvement technique relevant to a component member for holding a dust transfer section of a dust collection device.SOLUTION: A dust collection device 140 is fixed to an electric hammer 101 with a main body section 103 to which a removable side handle 110 can be attached. The dust collection device 140 has a dust collection hood 141 and a hose holding tool 145. The side handle 110 has a fixing ring 111, a grip section 121 and a grip fixing section 131 which are attached to the main body section 103. The grip section 121 is configured to be fixed to the grip fixing section 131 by moving relative to the grip fixing section 131 in a direction perpendicular to a longitudinal axial direction of a hammer bit 200. The hose holding tool 145 is held between the grip section 121 and the grip fixing section 131 through relative movement to fix the grip section 121. On the other hand, the dust collection hood 141 has an engagement groove 149a which engages with a dust collection hose 143 connected to a hose connection section 149 to prevent the dust collection hose 143 from being detached. |
