Abstract:
1. A power tool comprising: a power tool main body; a handle holder protruding from the power tool main body; a handle extending in a protruding direction of the handle holder and having an arm portion directly engaging the handle holder; and an elastic body carried between, and engaging, the power tool main body and the handle, wherein the handle holder has a convex outer circumferential face, wherein the arm portion surrounds the handle holder and has a concave inner circumferential face, wherein the convex outer circumferential face of the handle holder is inserted and fitted into the concave inner circumferential face of the arm portion, wherein the elastic body has a circular shape and is carried between, and engages, the power tool main body and the handle so as to surround the outer circumference of the handle holder in a direction concentric to a protruding-direction central axis of the handle holder, wherein the elastic body absorbs forces between the power tool main body and the handle caused by pivoting of the power tool main body relative to the handle, and wherein a movement of the convex outer circumferential face in a direction perpendicular to the protruding direction of the handle holder is regulated by the concave inner circumferential face.
