SOLUTION: A groove 2 is provided in the underside of the top board 1, an upright piece 4 is provided on the top face of the intermediate portion of a base piece 8 of a horizontal plate shape in a reinforcement material 3 directed to the same direction as the groove 2, the upright piece 4 is fitted into the groove 2, the both sides of the basic piece 8 extended out to both sides from the lower end of the upright piece 4 are secured on both sides of the groove 2 in the underside of the top 1.
