To improve the visibility on the boom side while securing the necessary rigidity in the cabin structure of a construction machine in which a work boom is arranged on the left or right side of the cabin body.SOLUTION: There is provided a cabin structure 1 for a construction machine which has right and left front pillars 3R, 3L and roof rails 4R, 4L extending rearward in the direction of the vehicle length from the upper ends of the front pillars 3R, 3L, and in which a work boom is arranged on the left or right side of a cabin body 2. At least the upper part of the front pillar 3L and at least the front part of the roof rail 4L on the side where the boom is arranged are missed, and a side sash assembly 8 with a sash frame 7 having a vertical member 5 thinner than the front pillar 3L and a horizontal member 6 thinner than the roof rail 4L is attached to a space S created by the missing parts. A front handrail 9L extending upward from the lower part of the cabin body 2 on the boom side is connected to the vertical member 5.SELECTED DRAWING: Figure 2

    【課題】キャビン本体の左または右側に作業用のブームが配置される建設機械のキャビン構造において、ブーム側の視界の向上を図ると共に、必要な剛性を確保する。【解決手段】左右のフロントピラー3R、3Lと、フロントピラー3R、3Lの上端から車長方向後方に延設されたルーフレール4R、4Lとを有し、キャビン本体2の左または右側に作業用のブームが配置される建設機械のキャビン構造1であって、ブームが配置される側のフロントピラー3Lの少なくとも上部とルーフレール4Lの少なくとも前部とが欠落され、欠落によって生じたスペースSに、フロントピラー3Lより細い縦材5とルーフレール4Lよりも細い横材6とを有するサッシュフレーム7を備えたサイドサッシュアッセンブリ8が取り付けられ、縦材5に、キャビン本体2のブーム側の下部から上方に延出されたフロントハンドレール9Lが連結されている。【選択図】図2
