PROBLEM TO BE SOLVED: To provide a shelf board support structure capable of securely preventing the shelf board from breaking due to a load although a shelf-engaging groove for engaging with a rail is provided at the bottom face of the shelf board. SOLUTION: The shelf board support structure A is provided with a shelf board 1 having a rail engaging groove 7 opened downward along the edge of a platy member and a downwardly projected hook part 6 than the top face at the outside from the rail engaging groove 7 and a rail 10 in which a shelf board engaging groove 11 in which the hook part 6 is inserted, a projected part 12 protruding upper side than the bottom face of the shelf board engaging groove 11 to be inserted in the rail engaging groove 7, and the shelf board support part 13 supporting the bottom face 14 of the shelf board 1 are formed in the order toward the inside from the outside. The height L1 of the top face of the rail engaging groove 7 against the bottom face 14 of the shelf board 1 is made higher than the height M1 of the projected part 12 against the shelf board support part 13, and the height L2 of the bottom face of the hook 6 against the bottom face 14 of the shelf board 1 is made higher than the height M2 of the groove bottom of the shelf board engaging groove 11 against the shelf board support 13.
