<p>It is an object of the invention to provide an effective technique for reducing the load of user's fingers in a power tool. A representative power tool (100) includes a body (101), a tool bit (110), a driving means (120) and a handgrip (130) that extends from a grip proximal end (130a) on the side of the body to a grip distal end (130le) in a direction that crosses the axial direction of the tool bit. The power tool includes a holding optimization region (107,109,130,132,134) that is arranged on the handgrip and shaped to match with the holding form of the fingers of the user when the user holds the handgrip. Specifically, the holding optimization region at least includes the rear end surface of the grip distal end region such that a normal on the rear end surface crosses an axis of the tool bit forward of the handgrip. As a result, according to the invention, the force of the user's fingers and palm on the handgrip can be optimized.</p> |
