Abstract
A representative power tool according to the invention performs a predetermined operation on a workpiece at least by axial linear movement of a tool bitcoupled to a front end region of a housing. The power tool includes driving mechanismsthat are housed within the housingand linearly drives the tool bit, and a dynamic vibration reducerthat has a weightwhich is allowed to linearly move under a biasing force of an elastic element, and reduces vibration caused during operation, by movement of the weightin the axial direction of the tool bit. A dynamic vibration reducer housing spacefor housing the weightand the elastic element of the dynamic vibration reduceris integrally formed with the housing
