Abstract: A dust collection device, that collects dust particles generated by an impact tool, has a feature that enables the attachment of the device to the impact tool, which is not provided with an attachment section for the device. The dust collection device has a tool body and an auxiliary handle, attached removably to the tool body, and is attached to an electric hammer that, in the lengthwise direction, linearly operates a tool bit mounted to the tip region of the tool body, and collects dust generated by the electric hammer. The dust collection device has: a dust collection unit that has a dust intake port at the tip; a dust collection hose, connected to the dust collection unit, for transferring dust to the downstream side; and a hose-holding unit that holds the dust collection hose. The hose-holding unit can be attached to and removed from the auxiliary handle.

Abstract: A power tool, such as a hammer drill (100), has first and second battery mount parts (160A, 160B) that are aligned in a longitudinal direction of the power tool. First and second batteries (170A, 170B) are mountable thereon in series along a straight line that extends in the longitudinal direction. The first battery (170A) is mounted on the first battery mount part (160A) by sliding along the straight line towards the second battery mount part (160B). The second battery (170B) is mounted on the second battery mount part (170B) by sliding along the straight line towards the first battery mount part (170A).

Abstract: An object of the invention is to provide an impact tool improved in vibration-proofing structure of a handle. A representative impact tool has a tool body and handle. The handle has a handle body and pair of grips that extend in a direction crossing an axial direction of a tool accessory, designed to be held by user's right and left hands. The handle body has a first part to which the grips are connected in a fixed manner and a second part that is connected to the tool body in a fixed manner. The first part is supported against the tool body via an elastic member and is allowed to move with respect to the tool body and the second part while being biased by an elastic force of the elastic member. A current supply cable, supplying current to a motor, is installed on the second part.

Abstract: A power tool (100) comprises a motor (110) operably driving a tool bit (119), a tool body (101) housing the motor (110), a handle (109) coupled to the tool body (101), and at least two battery mount parts (160 A, 160B) defined on the handle (109) and/or the tool body (101). Each of the battery mount parts (160 A, 160B) comprises a battery engaging part (161) configured to detachably engage with battery packs (170 A, 170B) by sliding the battery packs (170 A, 170B) relative to the battery engaging part (161) in a direction perpendicular to the longitudinal direction of the tool bit (119). In a state in which at least one of the battery packs (170 A, 170B) is mounted on at least one of the battery mount parts (160 A, 160B), a length of the mounted battery in a driving axis extending direction is shorter than a length of the mounted battery in a cross direction.
