PURPOSE:To strengthen the rigidity of the mounting seat of a leg and to prevent the occurrence of burrs of the end face by providing an edge at the outer periphery of the bottom of the leg made of a steel plate, and integrally molding a projection by further reducing the mounting seats of four corners. CONSTITUTION:A leg 2 of a steel plate to be mounted on a steel plate frame is formed with a projection 15 at the lower part by reducing except the edge 14 at the mounting seats 5 of four corners at the outer periphery. Further, the outer periphery of the projection 15 projected at mounting seats 5 and the opening end of the bottom of mounting hole 10 formed at the prescribed position are formed at a moderate slope. The bottom surface of the projection 15 is cut to be finished in the size of the central height of a rotational shaft of the prescribed rotary machine. This leg 2 is secured by holding and securing the projection 15 of the seat 5 with bolts at the threaded hole of a stationary base. |
