Abstract

　製造が容易であり且つ強度の高い作業機ブームを提供する。作業機ブーム（７）は、一端が建設機械の本体部に取り付けられ他端が作業機アームに取り付けられるものであり、ブーム本体（１１ａ）を備える。ブーム本体（１１ａ）は、管状素材が拡管されることにより一体成形されたものである。また、ブーム本体（１１ａ）は、基端側部分（２１）と、先端側部分（２２）とを有する。基端側部分（２１）は、本体部側に配置される第１端部（２４）を含み、第１端部（２４）側ほど水平方向の幅寸法が大きくなる形状を有する。先端側部分（２２）は、作業機アーム側に配置される第２端部（２５）を含み、第２端部（２５）側ほど水平方向の幅寸法が大きくなる形状を有する。
