- the point which the protrusion part 1I is provided in the edge part differs from the said 1st Embodiment.
- the protruding portion 1I is, for example, 1/13 to 5/13, more preferably 2/13 to the end of the lower wall portion 1G in the width direction of the vehicle body. It protrudes in the range of 4/13, and is 1/50 to 15/50, more preferably 2/50 to 5/50 from the wall surface of the lower wall portion 1G with respect to the width direction length of the lower wall portion 1G.
