To improve cooling performance of a battery while securing strength of a revolving frame.SOLUTION: A revolving frame comprises: a base plate 20 extending in a horizontal direction; a horizontal partition plate 30 extending in a width direction of the base plate 20 on the base plate 20; a pair of left and right front vertical partition plates 40 extending forward from the horizontal partition plate 30 with an interval in a width direction on the base plate 20; a rear strength member including a pair of left and right rear vertical partition plates extending backward from the horizontal partition plate 30 with a larger interval than that of the pair of front vertical partition plates 40 in a width direction on the base plate 20; and a center vertical partition plate extending backward from the horizontal partition plate 30 at a position between the pair of front vertical partition plates 40 in a width direction on the base plate 20.SELECTED DRAWING: Figure 2

    【課題】旋回フレームの強度を確保しつつ、バッテリの冷却性能を向上させる。【解決手段】水平方向に延びるベースプレート20と、該ベースプレート20上で、ベースプレート20の幅方向に延びる横仕切プレート30と、ベースプレート20上で、横仕切プレート30から前方に向かって幅方向に間隔をあけて延びる左右一対の前部縦仕切プレート40と、ベースプレート20上で、横仕切プレート30から後方に向かって、一対の前部縦仕切プレート40の間隔よりも大きく幅方向に間隔をあけて延びる左右一対の後部縦仕切プレートを有する後部強度部材と、ベースプレート20上で、一対の前部縦仕切プレート40の間の幅方向位置で、横仕切プレート30から後方に延びる中央縦仕切プレートと、を備える。【選択図】図2
