There is provided a revolving frame (11) provided with a bottom plate (13), left vertical plate (14) and a right vertical plate (15) installed upright on the bottom plate (13), and a front plate (16) arranged on a front side of the bottom plate (13) and connecting the left and right vertical plates (14), (15) to each other. A left reinforcing plate (22) is fixedly provided at a corner portion (23) where the left vertical plate (14) and the front plate (16) cross each other, and a right reinforcing plate (24) is fixedly provided at a corner portion (25) where the right vertical plate (15) and the front plate (16) cross each other. As a result, the corner portion (23) where the left vertical plate (14) and the front plate (16) cross each other is reinforced by the left reinforcing plate (22) while a left side closed space (LS) is formed, and the corner portion (25) where the right vertical plate (15) and the front plate (16) cross each other is reinforced by the right reinforcing plate (24) while a right side closed space (RS) is formed. As a result, a firm support structural body can be composed of the vertical plates (14), (15), the front plate (16), and the reinforcing plates (22), (24).
