PROBLEM TO BE SOLVED: To provide technology useful in reducing vibration at a hand grip while lightening a reciprocating type working tool and in improving cutting efficiency. SOLUTION: This reciprocating type working tool 101 has a working tool main body 103, a cutting tool 111, a working mechanism 121 to make the cutting tool carry out reciprocating linear motion and the hand grip 105. The hand grip and the working tool main body are connected to each other free to relatively revolve through an axis of revolution 147 in a direction to cross the reciprocating linear motion direction of the cutting tool, and the cutting tool is constituted to carry out reciprocating revolving motion with the working tool main body relative to the hand grip while carrying out the reciprocating linear motion through the working mechanism relative to the working tool main body in such a state that the hand grip is gripped by a worker. An elastic body to absorb input of vibration to the hand grip from the working tool main body by elastically receiving the relative reciprocating motion of the hand grip and the working tool main body is interposed between the hand grip and the working tool main body.
