Abstract

The invention provides a power tool which includes a tool bit, a first operating mechanism that linearly drives the tool bit and thereby causes the tool bit to perform a predetermined operation, and a dynamic vibration reducer 151 that reduces vibration in the operation of the tool bit. The dynamic vibration reducer includes a weight 153 that can linearly move under the action of biasing forces of a plurality of biasing springs 157 acting upon the weight 153 toward each other. The weight 153 is driven by a second operating mechanism 116 that mechanically excites at least one of the elastic elements, via the elastic element.
