PROBLEM TO BE SOLVED: To provide a framework structure of a rack which is capable of easily increasing the strength of the connection part of a support and a connection member configuring the framework structure of the rack.SOLUTION: In the framework structure of the rack, a joining plate portion 26 extended from the end of the connection member 6 connecting the supports with each other and abutting on the side surface of the support 5A is provided with an engaging portion 27c, and a portion 10c to be engaged for supporting the connection member, with which the engaging portion 27c is engaged downward, is provided on the side surface of the support 5A. On the engaging portion 27c and the portion 10c to be engaged, relative slidable contact portions 18a and 18b for generating action force in the direction of moving the connection member 6 and the support 5A so as to be relatively close to each other when the engaging portion 27c is engaged downward with the portion 10c to be engaged are formed. The connection member 6 and the support 5A are moved to be relatively close to each other by the action of the relative slidable contact portions 18a and 18b, and the end surface 25a of the folded portion 25 of the connection member 6 and the support 5A are abutted. |
