A power tool, which actuates a tool linearly in a longitudinal direction of the tool, the power tool performs a predetermined operation to a workpiece, having: a drive mechanism which actuates the tool; a rotational shaft which actuates the drive mechanism; a swing lever which swings along the longitudinal direction by a rotational motion of the rotational shaft; and a dynamic vibration reducer which alleviates vibration generated during the predetermined operation. The dynamic vibration reducer includes a weight which is linearly movable in the longitudinal direction an elastic member which biases the weight. The weight is adapted to be actuated mechanically and forcibly by a motion component with respect to the longitudinal direction of a swinging motion of the swing lever in a state that the weight is biased by the elastic member. |
