A representative impact tool includes a tool body, a lubricant sealed in the housing space, a driving mechanism, a tool holder, an angular positioning device disposed on a tip end side of the tool body and serves to fix a position of the tool bit around the axis with respect to the tool body. The angular positioning device includes first and second locking members. The first locking member is disposed between the tool body and the tool holder. The second locking member is disposed opposite to the first locking member. One end of the first locking member in the axial direction of the tool bit extends into the housing space of the tool body and is connected to the tool body within the housing space.

Abstract: It is an object of the present invention to provide an effective technique to alleviate vibration in the electric hammer drill. According to the invention, representative electric hammer drill is provided with a body, a motor, a striker, a cylinder, first and second power transmitting mechanisms, a power switching mechanism, a mode changing mechanism, and a coupling mechanism. The mode changing mechanism is disposed on the upper surface of the body and can change between a hammer-drill mode and a hammer mode. The coupling mechanism is disposed between the mode changing mechanism and the power switching mechanism. The coupling mechanism extends along the peripheral surface of the cylinder and transmits the mode changing movement of the mode changing mechanism to the power switching mechanism by moving in the longitudinal direction of the cylinder. Because the mode changing mechanism is disposed on the upper surface of the body and the coupling mechanism extends along the peripheral surface of the cylinder to move in the longitudinal direction of the cylinder, the center of gravity of the electric hammer drill is positioned nearer to the axis of the cylinder, compared with the known art in which the components for the switching the operation modes are centralized in one area. As a result, operating vibration of the electric hammer drill is effectively alleviated.

Abstract: A power tool includes a mode switching device that includes a mode switching member turned by manual operation, a linearly moving driven-side member and a mode switching mechanism actuated by linear motion of the driven-side member. The actuating member is disposed on the mode switching member such that the initial position of the actuating member is located in a position displaced in a radial direction from the rotation axis of the mode switching member. When the mode switching member is turned, the actuating member revolves in a circular arc movement in contact with the driven-side member to linearly move the driven-side member. The actuating member is structured to move radially inward of the mode switching member from the initial position toward the rotation axis of the mode switching member with respect to the mode switching member.

Abstract: A fastener tool includes a body having a driver guide mounted thereon. The driver guide extends downwardly from the body and has a longitudinal axis in a driving direction of fasteners. A control member may be movably mounted on the body for controlling a fastener driving operation. A support leg device serves to permit the tool to be placed on a surface in an upright position, in which the driver guide extends substantially vertically relative to the surface. The support leg device defines a predetermined support area extending in a plane for abutment with the surface. The support leg device is arranged such that the tool center of gravity is positioned directly above the support area in a plan view when the tool is in the upright position, in which the support area extends substantially horizontally, so that the control member does not substantially interfere with the surface.
