摘要： In a dust collection device that collects dust particles that an impact tool generates, disclosed is a feature that enables the attachment of the dust collection device to the impact tool, which is not provided with an attachment section for the dust collection device. The dust collection device (104) has a tool body (103) and an auxiliary handle (110) attached removably to said tool body (103), is attached to an electric hammer (101) that, in the lengthwise direction, linearly operates a tool bit (119) mounted to the tip region of the tool body (103), and collects dust that the electric hammer (101) generates. The dust collection device (104) has a dust collection unit (141) that has a dust intake port (141a) at the tip; a dust collection hose (146) that is connected to the dust collection unit (141) and that is for transferring dust to the downstream side; and a hose-holding unit (147) that holds the dust collection hose (146). The hose-holding unit (147) can be attached to and removed from the auxiliary handle (110).
