A clip-shaped spring body, which is made by folding a thin strip material in half and forming chevron-shaped elastic pieces on both sides or one side, is attached to a part of the body so as to span over the adjacent cell cells or the outer plate, and at least a part facing the spring body. Similarly, there is a spacer for a fuel assembly, which is made by folding a thin strip material in half and attaching a clip-shaped support body with rectangular or arc-shaped fixing protrusions on both sides so as to straddle adjacent cell cells.
