    摘要： PROBLEM
    To eliminate trouble of switching of a driving source when an attachment device is mounted or removed.
    SOLUTION TO THE PROBLEM
    A male terminal (57) is formed on a dust collecting device (40) so as to protrude therefrom, while a plug-in port (28) into which the male terminal (57) can be inserted, and a female terminal (27) that is located inside the plug-in port (28) and can be electrically connected to the male terminal (57), are provided in a hammer drill (1). When the dust collecting device (40) is joined to the hammer drill (1) and the male terminal (57) is electrically connected to the female terminal (27), a driving source is supplied from a battery pack (21) to the dust collecting device (40).

    摘要： 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).

    摘要： PROBLEM
    To provide a paper pack filter which can ensure a larger surface area for the same volume, simplify a folding operation upon replacement of the filter or the like, and require a minimum adhesion process.
    SOLUTION
    A paper pack filter 1 includes a paper filter mounting board 2 having a through-opening at a center part thereof and a paper filter 5 shaped like a tube having a bottom and an opening adhered to one surface of the paper filter mounting board 2, and the paper filter 5 is folded into an angular tube to form a bellows such that mountain fold portions 6 and valley fold portions 7 appear alternately at each side surface and the mountain fold portions 6 and the valley fold portions 7 shift alternately in a zig-zag manner between adjacent side surfaces.

    摘要： [Problem] To provide a technology for improving the usability of an impact tool. [Solution] A hammer drill (100) has a main housing (101) in which a motor housing (103) is united with a gear housing (105). An electric motor (110) is fixed in the motor housing (103). Meanwhile, a movement-converting mechanism (120) that is the impact mechanism section, an impact element (140) and a tool holder (159) are housed in the gear housing (105) so as to be capable of moving relative to the gear housing (105). During impact work, the impact mechanism section, on which the biasing force of a coil spring (171) is acting, moves relative to the gear housing (105) and vibrations generated by the impact work are reduced.
