It is an object of the invention to improve vibration reduction of a handle in a hand-held power tool. The representative power tool performs a predetermined operation on a workpiece by linear movement of a tool bit (119) in an axial direction of the tool bit. The power tool includes a power tool body (103), a handle (109) and a vibration-proofing part (159). The vibration-proofing part (159) includes an elastic element (152) that is disposed between the power tool body (103) and the handle (109) and serves to reduce transmission of vibration from the power tool body (103) to the handle (109), and also includes a body-side receiving part (153) and a handle-side receiving part (157) which are opposed to each other so as to hold the elastic element (152). The vibration-proofing part (159) is designed such that deformation of the elastic element (152) appears in the form of shearing deformation in each of the direction of a z-axis defined along the axial direction of the tool bit (119) and the directions of a y-axis and an x-axis which intersect with the z-axis. |
