    • An electrical power tool (1) includes a housing (10,20,30), an electrical motor (21), a motion conversion mechanism (36), a counterweight holding member (73), a counterweight (74), and support members (71,72). The electrical motor (21) is accommodated in the housing (10,20,30). The motion conversion mechanism (36) is configured to convert a rotary motion of the electrical motor (21) into a reciprocation motion. The counterweight holding 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 counterweight (74) is supported by the counterweight holding member (73) and is capable of reciprocating in the directions of reciprocation motion together with the counterweight holding member (73). The support members (71,72) are positioned away from the counterweight (74) by a predetermined distance for supporting the counterweight holding member (73) to the housing (10,20,30). The counterweight (74) is interposed between or among the support members (71,72).
    • 电动工具(1)包括壳体(10,20,30),电动机(21),运动转换机构(36),配重保持构件(73),配重(74)和支撑构件 (71,72)。 电动机(21)容纳在壳体(10,20,30)中。 运动转换机构(36)被构造成将电动机(21)的旋转运动转换成往复运动。 配重保持构件(73)在与往复运动方向垂直的方向上延伸,并且能够沿往复运动的方向弹性变形。 配重(74)由配重保持构件(73)支撑,能够与配重保持构件(73)一起沿往复运动方向往复运动。 支撑构件(71,72)远离配重(74)定位预定距离,用于将配重保持构件(73)支撑到壳体(10,20,30)。 配重(74)插入在支撑构件(71,72)之间或之中。
