- the rotational force of the gear 21 is transmitted to the balance weight 23, and the balance weight 23 repeats the raising and lowering operations.
- the direction in which the balance weight 23 operates has a phase opposite to the direction in which the plunger 31 and the saw blade 32 operate. That is, when the plunger 31 and the saw blade 32 are raised, the balance weight 23 is lowered. On the other hand, when the plunger 31 and the saw blade 32 are lowered, the balance weight 23 is raised. For this reason, the inertial force due to the reciprocating motion of the plunger 31 and the saw blade 32 and the inertial force due to the reciprocating motion of the balance weight 23 are offset, and the vibration of the jigsaw 11 can be reduced.

For this reason, it is not necessary to separately provide a mechanism for supporting the plunger 31 and the saw blade 32 so as to be movable in the vertical direction and a mechanism for supporting the plunger 31 and the saw blade 32 so as to be swingable. Therefore, the number of parts of the jigsaw 11 can be reduced, the size of the jigsaw 11 can be suppressed, and the manufacturing cost of the jigsaw 11 can be reduced.
- the plunger 31 does not move in the direction along the axis C ⁇ b> 1 with respect to the connector member 33. For this reason, it is not necessary to ensure the length of the plunger 31 in the direction along the axis C1 in accordance with the amount that the plunger 31 moves in the direction along the axis C1. Therefore, the dimension in the direction along the axis C1 of the plunger 31 can be shortened.
- connection portion 38 including the fulcrum D1 where the plunger 31 swings is disposed concentrically with the support shaft 28. For this reason, the distance between the fulcrum D1 and the needle bearing 29 can be shortened, and the gap amount between the connecting piece 30 and the guide plates 35 and 36 can be reduced.

- the motor that generates the power to be transmitted to the tip tool includes an electric motor, an engine, a hydraulic motor, and a pneumatic motor.
- the reciprocating tool of the present invention includes a saver saw in addition to a jigsaw as a cutting machine for cutting an object with a tip tool.
- the saver saw cuts an object when the saw blade reciprocates in the horizontal direction and the saw blade moves in a direction approaching an operator.
- the teeth of the saw blade are pointed down.
- the saver saw has a base that comes into contact with the object, and the base prevents the saver saw from approaching the object by a reaction force when the saw blade is pulled to cut the object.
