COUNTERWEIGHT
PROBLEM TO BE SOLVED: To provide a counterweight capable of suppressing an increase of board thickness of a vertical plate and reducing the cost.SOLUTION: A vertical plate 10 disposed to stand on a foundation 8 has a concavity 10a in the central part in a vertical direction Z. The concavity 10a is formed as a result of an end of the vertical plate 10 on a rear plate 3 side being recessed toward a front plate 2 so that width of the vertical plate 10 in a longitudinal direction Y progressively reduces as it approaches the center of the vertical plate 10 in the vertical direction Z.
【課題】縦板の板厚の増加を抑えてコストを低減させることができるカウンタウエイトを提供する。【解決手段】土台８上に立てて設けられた縦板１０には、上下方向Ｚの中央部に凹部１０ａが設けられている。凹部１０ａは、縦板１０の前後方向Ｙの幅が縦板１０の上下方向Ｚの中央に向かって漸減するように、縦板１０の後面板３側の端が前面板２の方に凹むことで形成されている。【選択図】図４
