Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a fork of a forklift, etc., from being collided with a girder wall in the vicinity of an inlet of a fork insertion hole, and the girder wall from being broken by forming a curved portion and an inclined portion on the girder wall located on both sides in the vicinity of the inlet of the fork insertion hole, and forming an inner wall reaching a back side from a face side in a girder. SOLUTION: Each girder wall of cylindrical girders 3, 4a, 4b located on both sides is formed into gradually curved portions 31, 4a1, 4b1 in the vicinity of an inlet of a fork insertion hole to be formed between the cylindrical girder 3 at a corner portion, the cylindrical girders 4a, 4b at an intermediate portion, and a cylindrical girder 5 at a center portion. Inner walls 32, 4a2, 4b21 along a peripheral side of a pallet are formed inside the cylindrical girders 3, 4a, 4b. In addition, end walls 321, 4a21, 4b2 located on both ends of the inner wall are substantially perpendicular in the tangential line of curved portions 31, 4a1, 4b1, and formed to reach the curved portions 31, 4a1, 4b1.
