摘要： An impact tool includes a reaction force transmitting member, a first elastic member that biases the transmitting member forward, and a second elastic member that is pushed by the transmitting member and compressively deforms when the transmitting member moves rearward by receiving a striking reaction force caused when a tool bit strikes a workpiece, thereby cushioning the force. When the tool bit is pressed against the workpiece, the transmitting member is pushed by the tool bit and compresses the first elastic member, and comes in contact with the second elastic member in an uncompressed state, so that the transmitting member is placed in a predetermined working position in the longitudinal direction. When the transmitting member receives the striking reaction force in the working position, the transmitting member moves rearward in the axial direction of the tool bit and compressively deforms the second elastic member, thereby cushioning the striking reaction force.

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： Improving vibration reduction of a handle in a hand-held power tool by performing a predetermined operation on a workpiece by linear movement of a tool bit in an axial direction. The power tool includes a power tool body, a handle and a vibration-proofing part. The vibration-proofing part includes an elastic element that is disposed between the power tool body and the handle and reduces transmission of vibration from the power tool body to the handle, and also includes a body-side receiving part and a handle-side receiving part which are opposed to each other so as to hold the elastic element. The vibration-proofing part is designed such that deformation of the elastic element is shearing deformation in each of the direction of a z-axis defined along the axial direction of the tool bit and the directions of a y-axis and an x-axis which intersect with the z-axis.
