Claim 0:
1. A power tool having a hammer mechanism configured to linearly drive a tool accessory along a driving axis defining a front-rear direction, the power tool comprising:
a tool body extending along the driving axis;
a motor housed in the tool body;
a handle (i) connected to the tool body to be movable in at least the front-rear direction relative to the tool body and (ii) including a cover part and a grip part, the cover part covering a portion of the tool body, the grip part being connected to the cover part and extending in a direction intersecting the driving axis;
at least one biasing member (i) between the tool body and the handle and (ii) configured to bias the tool body and the handle away from each other in the front-rear direction; and
at least one elastic member operatively between the tool body and the cover part of the handle such that an entirety of the at least one elastic member is movable relative to the tool body and the handle in the front-rear direction when the handle moves relative to the tool body in the front-rear direction, without deformation of the at least one elastic member in the front-rear direction, and is shear-deformable in response to a relative movement of the tool body and the handle,
wherein the at least one elastic member, the tool body and the cover part are configured such that:
when the handle moves relative to the tool body in the front-rear direction in specified range, the at least one elastic member is not subject to deformation due to shear forces; and
when the handle moves relative to the tool body in the front-rear direction beyond the specified range, the at least one elastic member is subject to deformation due to shear forces.
