Hand-held power tool

A hand-held power tool, which performs a predetermined operation on a workpiece by linear movement of a tool bit in an axial direction of the tool bit, the hand-held power tool comprising:

• a power tool body having a tip end region to which the tool bit can be mounted,
• a handle that is mounted on the power tool body and designed to be held by a user, the handle comprising an auxiliary handle which is mounted to a front region of the power tool body,
• an elastic element that is disposed between the power tool body and the handle and serves to reduce transmission of vibration from the power tool body to the handle,
• a body-side receiving part that is provided on the power tool body and supports the elastic element,
• a handle-side receiving part that is provided on the handle and supports the elastic element and
• a vibration-proofing part formed by the elastic element, and the body-side and handle-side receiving parts which are opposed to each other so as to hold the elastic element, wherein
• the vibration-proofing part is provided such that deformation of the elastic element appears in the form of shearing deformation in each of a direction of a z-axis defined along the axial direction of the tool bit and directions of a y-axis and an x-axis which respectively intersect with the z-axis, and
• the vibration-proofing part includes a rotation preventing mechanism which allows the auxiliary handle to move with respect to the power tool body in the directions of the z-, y- and x-axes by deformation of the elastic element and prevents rotation of the auxiliary handle about the y-axis.
