To provide an effective technique for avoiding increase of size of a working tool, while performing a vibration damping action during fabrication with the working tool.

The working tool includes a motor 111, a housing 103 storing an internal mechanism 113 driven by the motor 111, a tool bit 119 arranged on one end part side of the housing, a hand grip 102 connected to the other end part side of the housing. The working tool includes a dynamic vibration absorber 151, having a weight 155 capable of performing a linear motion while an energizing force is working in a counter manner by a plurality of elastic elements 157, for performing vibration damping during fabrication by the movement of the weight 155 in the longitudinal axis direction of the tool bit. The dynamic vibration absorber 151 is arranged so that the vibration damping direction of the dynamic vibration absorber is equal to the tool bit longitudinal axis direction by utilizing a space 201 between the housing and the internal mechanism.
