Abstract: A reciprocating tool includes a motor, a driving mechanism, a body housing, a movable part, and a vibration control mechanism. The driving mechanism includes a reciprocating member configured to reciprocate in a first direction. The movable part is connected to the body housing via a first elastic member and a second elastic member to be relatively movable in the first direction. The vibration control mechanism includes at least one weight configured to move in a direction opposite to the reciprocating member. The center of gravity of the at least one weight is offset from the driving axis in a second direction. In the second direction, the first elastic member is closer to the center of gravity than the second elastic member. A load of the first elastic member when the movable part is placed in a closer position is smaller than a load of the second elastic member.

Abstract: A driver drill may have two battery attachment portions to which two rechargeable batteries can be attached. Therefore, the driver drill can meet a need for an increased voltage or an increased discharge capacity. Further, the two battery attachment portions may be constructed as slide-fitting battery attachment portions. A combined gravity center of the rechargeable batteries attached to the first and second battery attachment portions may be positioned on a vertical line through a gravity center of a tool main body in a condition in which the two rechargeable batteries are detached therefrom.
