Abstract:
A reciprocating tool includes a motor, a crank, a connecting rod, a rod, a tool bit, and a counter weight. The tool bit is mounted such that the action portion is positioned on a side opposite to a side with the rod central axis or the extended line of the rod central axis viewing from the rotational center of the crank. The first eccentric shaft and the second eccentric shaft are disposed such that at a position where the first eccentric shaft causes the rod to reach top dead center (TDC), the second eccentric shaft causes the counter weight to reach bottom dead center (BDC) or a point before the BDC, and at a position where the first eccentric shaft causes the rod to reach the BDC, the second eccentric shaft causes the counter weight to reach a point before the TDC.
