摘要：
The present invention therefore proposes that a shearing rigidity in respect to a vertical load in the portion near the body bolster (A) of a light weight car body (1) is made larger than that of the portion other than a portion near the body bolster (A). That is, a shearing rigidity in respect to the vertical load of a portion near the portion of body bolster (A) of the car body (1) is improved and the portion other than the portion near the body bolster (A) of the car body (1) has a sufficient bending rigidity in the same manner as that of the prior art structure.
