    摘要： 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).

    摘要： A technique which contributes to improvement of usability is provided in a power tool having a dust suction device for sucking dust generated during operation. The power tool performs a predetermined operation by using a tool bit 119 and has a grip part 181 and a dust suction device 250. The dust suction device 250 has a dust suction part 251 that extends in an axial direction of the tool bit 119 and sucks and collects dust generated during operation at a tip of the tool bit, and the dust suction part 251 can be moved between a first position in which the dust suction part covers a bit tip 119a of the tool bit 119 and a second position in which the bit tip 119a is exposed. The dust suction device 250 further has an operation mode switching mechanism 253 that is capable of switching between a first operation mode in which the dust suction part is allowed to move between the first and second positions and a second operation mode in which the dust suction part is locked in the second position, and the operation mode switching mechanism 253 is provided in a region of the grip part 181 or its vicinity such that it can be operated with a user's hand holding the grip part.
