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 bit 119 coupled to a front end region of a housing 103. The power tool includes driving mechanisms 113, 115 that are housed within the housing 103 and linearly drives the tool bit 119, and a dynamic vibration reducer 151 that has a weight 153 which is allowed to linearly move under a biasing force of an elastic element, and reduces vibration caused during operation, by movement of the weight 153 in the axial direction of the tool bit. A dynamic vibration reducer housing space 149 for housing the weight 153 and the elastic element of the dynamic vibration reducer 151 is integrally formed with the housing 103.
Claims8
A power tool, which performs a predetermined operation on a workpiece at least by axial linear movement of a tool bit coupled to a front end region of a housing comprising:
