PROBLEM TO BE SOLVED: To address a requirement of balance weights for working machines, which can be vertically superposed in a stable state and, the attachment/detachment work of which is facilitated.SOLUTION: Balance weights 10 for working machines attachable to a machine body in a vertically superposed manner, each includes: a pair of left/right boss parts 12 protruding to the lower surface; a pair of left/right first recessed parts 13 formed on the upper surface at positions corresponding to the boss parts 12 in plane view; a pair of left/right opening parts 17 laterally downward opening the first recessed pars 13; and a pair of left/right linear through-holes 18 extending across the first recessed parts 13 and the boss parts 12. When the balance weights are vertically superposed, the pair of left/right boss parts 12 and the pair of left/right first recessed parts 13 of the mutually superposed balance weights 10 are fitted to each other so as to match plane positions of the pair of left/right through-holes 18 of the mutually superposed balance weights 10.
【課題】バランスウエイトを安定した状態で上下に積み重ねることができ、かつ、バランスウエイトの着脱作業が容易な作業機用のバランスウエイトが要望されている。【解決手段】上下に積み重ねて機体に取付可能な作業機用のバランスウエイト10であって、下面に突設された左右一対のボス部12と、上面のうち平面視でボス部12と対応する位置に形成された左右一対の第一凹入部13と、第一凹入部13を横外方向きに開放させる左右一対の開放部17と、第一凹入部13とボス部12とに亘る直線状の左右一対の貫通孔18と、を備え、上下に積み重ねる際に、互いに積み重なるバランスウエイト10の左右一対のボス部12と左右一対の第一凹入部13とが嵌り合って、互いに積み重なるバランスウエイト10の左右一対の貫通孔18同士の平面位置が揃うように構成されている。【選択図】図5
