    Abstract: A technique for reducing the costs of manufacturing an auxiliary handle provided separately from a main handle in a hand-held power tool is provided. A hand-held power tool (101) includes a power tool body (103) having a front end region to which a tool bit (119) can be mounted, a main handle (109) that is disposed on a rear end side of the power tool body (103) opposite from the tool bit (119), an auxiliary-handle mounting member (108) for mounting an auxiliary handle (110), and longitudinally elastic elements (151, 152) that are disposed between the power tool body (103) and the auxiliary handle mounting member (108) in the axial direction of the tool bit (119) and can elastically deform in the axial direction. The auxiliary-handle mounting member (108) is allowed to move with respect to the power tool body (103) in the axial direction of the tool bit (119) by elastic deformation of the longitudinally elastic elements (151, 152), so that transmission of vibration from the power tool body (103) to the auxiliary-handle mounting member (108) in the axial direction is reduced.

    Abstract: A vibration reduction apparatus for use with a hammer tool having a hammer piston is disclosed. The hammer piston is caused to reciprocate in the cylinder by rotation of a gear wheel and crank drive. A cam is mounted around the gear wheel, a counterweight surrounds the piston cylinder, and a cam follower is provided on the counterweight. The cam follower on the counterweight is urged into contact with the cam by a biasing element. The external profile of the cam is such that rotation of the gear wheel causes oscillation of the counterweight in antiphase to motion of the hammer piston to counteract vibrations produced by operation of the hammer action of the tool. A mechanism is provided to deactivate the vibration reduction apparatus when the hammer action of the tool is deactivated.
