Abstract: A vehicle cushioning member includes first and second bending portions including first and second convex-bending portions, and first and second concave-bending portions. The first and second convex-bending portions and the first and second concave-bending portions are formed perimetrically while switched from each other between the adjacent side walls. When a length from a top surface of the top plate to a flange portion is 100%, a length from the top surface to the first bending portion is 24% or more and 47% or less, a length from the first bending portion to the second bending portion is 34% or more and 49% or less, and a length from the second bending portion to a top-plate-side surface of the flange portion is 13% or more and 33% or less, concerning a height direction along the axis of a substantially polygonal tube.
