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： 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.

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： It is an object of the invention to reduce transmission of an external force caused by run-out of a tool bit to a tool body in a power tool is provided. A representative power tool which performs a predetermined operation by linear motion of a tool bit (119) in its axial direction has a tool body (103), a tool holder (137) that holds the tool bit (119) in its front end region and extends in the axial direction of the tool bit, and an elastic element (155). A rear region of the tool holder (137) opposite from the front end region extends into the tool body (103), and in the extending region, the tool holder (137) is coupled to the tool body (103) such that the tool holder can rotate about a pivot (P) on a z-axis defined by an axis of the tool bit, in directions of y- and x-axes which intersect with the z-axis. The elastic element (155) applies a biasing force to the tool holder (137) in such a manner as to hold the tool holder (137) in a predetermined position or an initial position with respect to the tool body (103).

摘要： An electric hammer comprising a hammer bit (313) performing hammering work on a work, a drive motor, a hammering piece (334) driven by the drive motor to apply a hammering force to the hammer bit, and a mechanism (371) for damping vibration generated during hammering. The damping performance of the electric hammer is enhanced by causing the driving amount applied to the damping mechanism (371) to vary between a first mode where the damping mechanism (371) generates vibration corresponding to the vibration of the hammer bit (313) subjected to an external force from the work during the load diving time and thereby optimizes the damping and a second mode where the damping mechanism (371) generates vibration corresponding to the vibration of the hammer bit (313) not subjected to an external force from the work during the no-load driving time and optimizes damping.

摘要： [Problem] To provide an effective technique for further improving the vibration reducing performance of a power tool. [Means for Solving the Problem] The invention provides a power tool which includes a tool bit, a first operating mechanism that linearly drives the tool bit and thereby causes the tool bit to perform a predetermined operation, and a dynamic vibration reducer 151 that reduces vibration in the operation of the tool bit. The dynamic vibration reducer includes a weight 153 that can linearly move under the action of biasing forces of a plurality of biasing springs 157 acting upon the weight 153 toward each other. The weight 153 is driven by a second operating mechanism 116 that mechanically excites at least one of the elastic elements, via the elastic element.
