Patent abstract
An impact tool is provided that can efficiently reduce the vibration resulting from the striker and that does not lead to a larger design even with the use of a counterweight mechanism. A counterweight mechanism is provided in a motion converter housing, facing the handle. The counterweight mechanism is positioned between a center of gravity of the impact tool and the grip of the handle and is positioned above the control substrate. The counterweight mechanism is equipped with a first support, a second support, a weight support member, and a counterweight.
