摘要：
配重(21)利用以下部分构成：主配重部(22)，其处于以旋转轴孔(24)侧为中心的圆弧周缘(22C)与隔着旋转轴孔(24)而位于圆弧周缘(22C)的两侧的一对假想端面(22D)之间的范围；一对延长配重部(23)，其从主配重部(22)的一对假想端面(22D)隔着旋转轴孔(24)相对于圆弧周缘(22C)向圆弧的相反侧延伸；旋转轴孔(24)，其设置于主配重部(22)而位于圆弧周缘(22C)的中心侧；曲轴安装突起(25)，其从旋转轴孔(24)向圆弧的相反侧突出设置；曲轴孔(26)，其在曲轴安装突起(25)上与旋转轴孔(24)在径向上偏心地设置；一对空隙(27)，其分别形成在隔着曲轴安装突起(25)的两侧位置与一对延长配重部(23)之间。
摘要（英）：

A balance weight (21) comprises: a main weight section (22) located within the range between an arc-shaped peripheral edge (22C) centered on the rotation shaft hole (24) side and a pair of imaginary end faces (22D) located on both sides of the arc-shaped peripheral edge (22C) with the rotation shaft hole (24) sandwiched between the pair of imaginary end faces (22D); a pair of extension weight sections (23) extending from the pair of imaginary end faces (22D) of the main weight section (22) in the direction opposite the arc-shaped peripheral edge (22C) with the rotation shaft hole (24) sandwiched between the pair of extension weight sections (23); the rotation shaft hole (24) located on the center side of the arc-shaped peripheral edge (22C) and provided in the main weight section (22); a crankshaft mounting protrusion (25) provided protruding from the rotation shaft hole (24) in the direction opposite the arc shape; a crankshaft hole (26) provided in the crankshaft mounting protrusion (25) so as to be radially eccentric relative to the rotation shaft hole (24);and a pair of air gaps (27), which are each formed between each of the sides of the crankshaft mounting protrusion (25) and one of the pair of extension weight sections (23).
