Zusammenfassung:To facilitate attaching and detaching a canopy and reduce looseness of the canopy.SOLUTION: The hydraulic shovel includes: a cab that is positioned so as to be offset to one side of left and right directions from a revolving center; a plurality of posts 55 that are provided for a revolving body; and a canopy 50 that is supported by the plurality of posts and covers the cab from above. The canopy includes a plurality of cylindrical columns 51 to 53 that cover the posts and a roof that is supported by the plurality of columns and is positioned above the cab. The hydraulic shovel is provided with: a slit 64 that is provided for the lower end of each of the plurality of columns of the canopy; a pair of brackets 71, 72 that are provided for a column so that they are positioned on both sides of the slit; a cam mechanism 73 that moves the pair of brackets back and forward; and a lever 74 that operates the cam mechanism. The slit is tightened by operation of the lever using the cam mechanism via the pair of brackets, so as to reduce an inner diameter of a column to fix the column to a post.SELECTED DRAWING: Figure 8 【課題】キャノピの脱着作業を容易化し、キャノピのガタツキを少なくする。【解決手段】旋回中心に対して左右方向の一方側にオフセットして配置された運転席、旋回体に設けた複数のポスト55、及び複数のポストに支持されて運転席の上方を覆うキャノピ50を備えており、キャノピが、ポストに被せられた筒状の複数の支柱51〜53、及び複数の支柱で支持されて運転室の上方に配置されたルーフを備えた油圧ショベルにおいて、キャノピの複数の支柱の下端部にそれぞれ設けたスリット64と、スリットを跨いで両側に位置するように支柱に設けた一対のブラケット71,72と、一対のブラケットを互いに進退させるカム機構73と、カム機構を操作するレバー74とを設け、レバーを操作してカム機構で一対のブラケットを介してスリットを締め込むことで、支柱の内径を収縮させて支柱がポストに固定されるようにする。【選択図】図8
