Disclosed is a feature that contributes to an improvement in the attachment to an impact tool of a dust collection device that is attached to the impact tool and that collects dust particles that said impact tool generates. The dust collection device (140) collects dust that the impact tool (101) generates and is attached to said impact tool (101) that, in the lengthwise direction, linearly operates a tool bit (119) that is mounted to the tip region of a tool body (103). The dust collection device (140) has a dust collection unit (141, 143) that has a dust intake port (141a) at the tip; and a dust transfer unit (146) that is connected with the dust collection unit (141, 143) in order to transfer dust sucked in from the dust intake port (141a) towards the downstream side. The dust collection unit (141, 143) is held by the shaft section (119b) of the tool bit (119), and the dust transfer unit (146) is held by the tool body (103).

The present invention improves dust collection performance while suppressing an increase in body size. A dust collection device 40 comprises: an intake pipe 53 connected to a suction unit 52; a cyclone unit 60 that swirls air flowing out from the intake pipe 53 and centrifuges dust; and a filter unit 70 that accommodates a filter 72. The filter unit 70 has an outlet 74 connected to the cyclone unit 60 and discharging the air having passed through the filter 72. Therefore, the air and dust near a tip tool T can be separated by the cyclone unit 60. Furthermore, even when the dust remains, the remaining dust can be removed by the filter 72. Furthermore, the intake pipe 53 and the cyclone unit 60 are arranged at positions where the intake pipe 53 and the cyclone unit 60 overlap in a front-rear direction, and the filter unit 79 is disposed behind the cyclone unit 60. Therefore, as compared to a case where the filter unit 70 is disposed below the cyclone unit 60, an increase in the body size of the dust collection device 40 in the vertical direction can be suppressed.

Disclosed is a feature that contributes to an improvement in visibility from a tool bit to a work region in a dust collection device that collects dust particles that arise by means of a processing operation of an impact tool. The dust collection device (140) collects dust that arises by means of a processing operation and is attached to the impact tool (101) that performs a predetermined processing operation on a processed member by means of a tool bit (119) mounted to the tip region of the tool body (103) being linearly operated at least in the lengthwise direction. The dust collection device (140) has a dust collection unit (141) of which the tip opens as a dust intake port (141a) and the contour shape is formed unevenly around the long axis of the tool bit (119). The position ofthe dust collection unit (141) is freely selected around the long axis ofthe tool bit, and it is possible to cause the position to change around the long axis of the bit.

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).

In a dust collection device that collects dust particles that an impact tool generates, disclosed is a feature that can accommodate the lengths of tool bits that are mounted to the impact tool when a machining operation is executed by exchanging tool bits of different lengths. The dust collection device (140) collects dust that the impact tool (101) generates and is attached to said impact tool (101) that, in the lengthwise direction, linearly operates the tool bit (119) mounted to the end region of a tool body (103). The dust collection device (140) has a dust intake port (141a) that sucks dust, and said dust intake port (141 a) can be repositioned in the lengthwise direction of the tool bit (119) in accordance with the length in the lengthwise direction of said tool bit (119).

[TASK] To achieve good dust suction efficiency by removing powder dust remaining in a hose and the like with a simple structure. [MEANS FOR SOLVING THE PROBLEM] A dust suction chamber 11 formed in a dust suction hammer drill 1 is provided with a fan shaft 15 integrally rotating with an output shaft 7 of a motor 6, and a suction fan 18 externally fitted to the fan shaft 15. A one-way clutch 19 is provided between the fan shaft 15 and the suction fan 18. The one-way clutch 19 transmits rotation to the suction fan 18 by means of rotation of the fan shaft 15 and cuts off the transmission of rotation to the suction fan 18 when the fan shaft 15 is decelerated, so as to cause the suction fan 18 to rotate by inertia.
