PROBLEM TO BE SOLVED: To provide a lightweight attachment of construction machinery, which can effectively relieve stress concentration and which is excellent in durability.SOLUTION: An attachment of construction machinery comprises a plurality of component members that include a hollow support member 62 and that are rotatably connected to one another, and a hydraulic cylinder 64 that rotates the adjacent component members. The support member 62 has a body part B having a rectangular cross-sectional surface, and a bracket 69 that is provided on a surface of a first plate material 81a to pivotally support the hydraulic cylinder 64. A reinforcing member 84, which is joined to the back side of the first plate material 81a and respective opposed surfaces of third and fourth plate materials 81c and 81c to form a closed section structure within the body part B, is provided on the opposite side of the bracket 69.SELECTED DRAWING: Figure 4
【課題】応力の集中が効果的に緩和でき、軽量で耐久性に優れた建設機械のアタッチメントを提供する。【解決手段】中空の支柱部材６２を含む、互いに回動可能に連結された複数の構成部材と、隣接した構成部材を回動させる油圧シリンダ６４とを備える。支柱部材６２は、矩形の横断面を有する本体部Ｂと、第１板材８１ａの表面に設けられて、油圧シリンダ６４を軸支するブラケット６９とを有している。第１板材８１ａの裏面と、第３、第４の板材８１ｃ，８１ｃの各対向面とに接合されて、本体部Ｂの内部に閉断面構造を形成する補強部材８４が、ブラケット６９の反対側に設けられている。【選択図】図４
