摘要： Representative impact tool according to the invention includes a reaction force transmitting member 161 that receives a striking reaction force caused when a tool bit 119 strikes a workpiece, a first elastic member 163 that biases the reaction force transmitting member 161 forward, and a second elastic member 171 that is pushed by the reaction force transmitting member 161 and compressively deforms, thereby cushioning the striking reaction force, when the reaction force transmitting member 161 moves rearward by receiving the striking reaction force. When a user presses the tool bit 119 against the workpiece, the reaction force transmitting member 161 is pushed by the tool bit 119 and compresses the first elastic member 163, and also comes in contact with the second elastic member 171 in an incompressible state, so that the reaction force transmitting member 161 is placed in a predetermined working position in the longitudinal direction, and when the reaction force transmitting member receives the striking reaction force in the working position, the reaction force transmitting member moves rearward in the axial direction of the tool bit and compressively deforms the second elastic member 171, thereby cushioning the striking reaction force.
摘要翻译：根据本发明的代表性冲击工具包括反作用力传递构件161，其接收当工具钻头119撞击工件时引起的打击反作用力，将反作用力传递构件161向前偏压的第一弹性构件163和第二弹性构件 171，当反作用力传递构件161通过接收击打反作用力而向后移动时，被反作用力传递构件161推动并且压缩变形，从而缓冲撞击反作用力。当使用者将工具位119按压在工件上时，反作用力传递构件161被工具钻头119推压并压缩第一弹性构件163，并且在不可压缩状态下也与第二弹性构件171接触，因此反作用力传递构件161沿纵向放置在预定的工作位置，并且当反作用力传递构件在工作位置接收到打击反作用力时，反作用力传递构件沿着工具的轴向向后移动并且使第二弹性构件171压缩变形，从而缓冲击打反作用力。

摘要： 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.

摘要： A hammer drill includes, in a cylinder accommodated in a housing, a piston configured to advance and retract and an impact element to operate together with the piston with an air chamber interposed therebetween, and a bit mounted in a front part of a tool main body so that an impact operation can be transmitted to the bit by advancing and retracting movement of the impact element. Vent holes are provided in the cylinder, and configured to discharge air in the air chamber to outside of the cylinder, and to introduce the air outside the cylinder into the air chamber by the movement of the piston. One of the vent holes is located at a center of an upper half of a periphery of the cylinder and the other vent hole is located in a lower half of the periphery of the cylinder.
