PROBLEM TO BE SOLVED: To reduce the load when a pair of lock bars are horizontally moved in the approaching direction to each other, and to facilitate the assembly work of a folding container. SOLUTION: A lock member L consisting of a pair of lock bars Lb movable in a horizontal direction and one operation portion La is disposed on each of side walls 3 brought down first. An inclined spring member 12 is provided in the operation portion and with a tip portion being placed in a spring receiving and supporting block 3n formed on each of the side walls brought down first. A cam hole portion 21a is formed in each of the lock bars, into which a driven short shaft 15 formed on the operation portion is inserted. A spring member 22 is formed on each of the lock bars and configured to come into abutting contact with a spring member abutting block 3x which is formed on each of the side walls brought down first, so that when the lock bars are moved in a direction in which the lock bars approach each other, the operation portion is prevented from being moved by the movement of the lock bars in the direction when the lock bars approach each other.
