Abstract: A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod. The counterweight moves vertically independently of the vertical movement of the rod which is produced by the power transmission portion.
