摘要： In an arm for a construction machine formed as a box-shaped structural body by left and right side plates, an upper plate, a lower plate, and a rear plate, a left rear thick side plate constituting the left side plate, a right rear thick side plate constituting the right side plate, a rear thick upper plate constituting the upper plate, and a rear thick lower plate constituting the lower plate are formed by using a soft steel material having a large plate thickness. A left front thin side plate constituting the left side plate, a right front thin side plate constituting the right side plate, a front thin upper plate constituting the upper plate, and a front thin lower plate constituting the lower plate are formed by using a high tensile steel material having a small plate thickness. As a result, the weight of the entire arm can be reduced.
