Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress deformation of a grid and lengthen the life by specifying the ratio of the area of the region where the shape of a part surrounded by frames formed by development becomes a triangle to the area of a grid development part. SOLUTION: Expanded grid structure having a grid development part (net part) 5 formed by developing a lead sheet in the lower part of an upper frame 4 is formed. In the case that the shape surrounded by frames formed by development is a rhombus, the rhombus easily deforms in the longitudinal direction or the lateral direction when stress is applied, but in the case that the shape is a triangle, the deformation in the longitudinal direction or the lateral direction is structurally suppressed. The relation of the area A of the region of the part 6 where the shape of the part surrounded by frames formed by development becomes a triangle to the area S of the whole grid development part 5 is specified to 0.1
