PROBLEM TO BE SOLVED: To provide a revolving frame of a work machine which makes buckling less likely to occur while inhibiting increase of the weight.SOLUTION: Reinforcement members 5 are respectively attached to side surfaces of a pair of side plates 3 at the inner side of the pair of side plates 3 which face each other in a horizontal direction B. Each reinforcement member 5 inclines in an upward direction from the front side of a revolving frame 1 to the rear side and is disposed at the rear side relative to a revolving center O of a revolving bearing 22.

    【課題】重量の増加を抑えながら座屈しにくくすることができるようにする。【解決手段】左右方向Bに対向する一対の側板3の内側において、一対の側板3の側面には、補強部材5がそれぞれ取り付けられている。補強部材5は、旋回フレーム1の前側から後ろ側に向かって下から上に傾斜しているとともに、旋回ベアリング22の旋回中心Oよりも後方に配置されている。【選択図】図2
