摘要： Provided is a work tool by which it is possible to ensure vibration damping effects even if a vibration-reducing mechanism is disposed to a side surface of a housing to reduce a total length of the device. A work tool (1) having an electric motor, a power transmission means that receives motive power from the electric motor and transmits the motive power to a tip tool, a gear housing (30) for accommodating at least a portion of the power transmission means, weights (80) swingably supported on the gear housing (30), and coil springs (71) that function as an urging means for urging the weights (80) such that the weights (80) are located at an initial neutral position, wherein the weights (80) and the coil springs (71) are provided respectively on the two sides of the gear housing (30) so as to put the power transmission means therebetween, and a rotational support axle (72) is provided that functions as a connecting means for connecting the weights (80) provided on both sides of the gear housing (30) so as to connect the weights (80) such that the weights (80) swing integrally.
