<p>It is an object of the invention to provide a technique that contributes to improvement of the vibration reducing performance of a dynamic vibration reducer (151) in a power tool (101) while realizing reduction in size of the dynamic vibration reducer (151). A representative power tool (101) which linearly drives a tool bit (119) to perform a predetermined operation on a workpiece includes a tool body (103) and a dynamic vibration reducer (151). The dynamic vibration reducer (151) has a weight (155) and an elastic element (157). The weight (155) has an internal space (156) that extends in the axial direction of the tool bit from at least one end of the weight (155) in said axial direction. One end of the elastic element (157) is inserted and received in the internal space (156), while the other end of the elastic element is placed on the tool body (103) directly or via the body side member.</p> |
