<p>An electrical power tool (1) includes a housing (20,30), an electrical motor (21), a motion conversion mechanism (36), a weight-supporting member (73), a counterweight (74), and a first supporting member (71) and a second supporting member (72). The motion conversion mechanism (36) is configured to convert a rotary motion of the electrical motor (21) into a reciprocation motion. The weight-supporting member (73) extends in a direction perpendicular to directions of the reciprocation motion and is capable of being elastically deformed in the directions of the reciprocation motion. The first supporting member (71) and the second supporting member (72) are each provided on the housing for supporting the weight-supporting member (73) to the housing (20,30). The weight-supporting member (73) has a first connecting part (73B: fig 4) and a second connecting part (73C: fig 4) supported by the first supporting member (71) and the second supporting member (72), respectively; and an elastically deforming part (73D: fig 4). The elastically deforming part (73D) is positioned between the first connecting part (73B) and the second connecting part (73C) and has a mounting part for mounting the counterweight. The elastically deforming part (73D) includes a portion (73D1,73D2) having a smaller cross-sectional area than each cross-sectional area of the first connecting part (73B) and the second connecting part (73C).</p> |
