<p>PROBLEM TO BE SOLVED: To provide a reciprocating tool capable of reducing the weight of a plunger and vibrations with a low cost.SOLUTION: A jig saw 11 is equipped with a power unit 16 for outputting rotational movement, a decelerating portion 22 for decelerating the rotational movement outputted from the power unit 16, a connecting piece 31 provided eccentrically to the decelerating portion 22, a plunder 36 reciprocating in a vertical direction, and a connector 38 provided on a part of the plunder 36. The connector 38 is engaged with the connecting piece 31 to convert the rotational movement into reciprocating movement of the plunger 36 and add the reciprocating movement to a tip end tool 40 attached to the plunger 36. The connector 38 is provided with a single projection strip portion 38b, and the connecting piece 31 is provided with an engaging portion 31a engaged with the projection strip portion 38b.</p> |
