Abstract
It is an object of the invention to provide a technique for bringing a center of gravity of a battery-powered power tool closer to a working axis of a tool bit in the battery-powered power tool.The battery-powered power tool performs an operation by movement of a tool bit 119 in an axial direction of the tool bit. The power tool includes a battery 110, a motor 111 that is driven by power supply from the battery 110, a mechanical arrangement 113, 115, 117 that drives the tool bit 119 by rotative power transmitted from the motor 111, and a tool body 103 that houses the motor 111 and the mechanical arrangement 113, 115, 117 and has a front end region in which the tool bit 119 is disposed. A sum of weights of the motor 111 and the battery 110 is smaller than a weight of the mechanical arrangement 113, 115, 117.
