The weight frame 7 includes a pair of left and right vertical columns 9L and 9R having U-shaped horizontal sections, an upper beam 11 for connecting the vertical columns upward, and a lower beam 13 for connecting the vertical columns downward, and reinforcing members 24 are fitted to the vertical columns 9L and 9R along a vertical direction.SELECTED DRAWING: Figure 1 |
