A power tool, which actuates a tool (119) linearly in a longitudinal direction of the tool (119) the power tool performs a predetermined operation to a workpiece, comprising: a drive mechanism (113,115) which actuates the tool (119); a rotational shaft (121) which actuates the drive mechanism (113, 115); a swing lever (167) which swings along the longitudinal direction by a rotational motion of the rotational shaft; and a dynamic vibration reducer (151) which alleviates vibration generated during the predetermined operation. The dynamic vibration reducer (151) includes a weight (153) which is linearly movable in the longitudinal direction an elastic member (155F, 155R) which biases the weight (153). The weight (153) 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 (167) in a state that the weight (153) is biased by the elastic member (155F, 155R). |
