In the upper face plate 41, rectangular holes 51b are formed in the face plate 41, which is one side of the truss, at predetermined intervals along the extrusion direction. The hole 51b is shorter in the extrusion direction. Face plate 4 which is the side of the adjacent truss
1 also has a hole 51c. The holes 51c are arranged at predetermined intervals along the extrusion direction. The shape of the hole 51c is the same as the hole 51b. The hole 51c is between the adjacent holes 51b. That is, the hole 51 (the holes 51b, 5
1c is referred to collectively. ) Are arranged in a staggered pattern.
【００１７】下面の板４２にも孔５１と同様に孔５２を

００mm程度である。For example, the pitch of the truss (the pitch of the truss in the width direction of the hollow member) is 130 mm, the size of the holes 51 and 52 is 80 mm × 30 mm, and the pitch of the holes 51b (51c) is 3 mm.
It is about 00 mm.

This is a triangular second region closer to the bolster 35 than the line. Since this triangular region is located on the side surface of the center beam 36, there are two regions. Holes 51 and 52 are mainly provided in the first region and the second region. For example, as shown in FIG. 1, the pitch in the longitudinal direction and the width direction of the hole 51 in the region and a hole 52 described later are reduced, or the size of the holes 51 and 52 is reduced. Holes 51 and 52 may be provided outside the region.
