PROBLEM TO BE SOLVED: To provide a connection structure of vertical frame members to horizontal frame members capable of connecting the vertical frame members to the horizontal frame members with only screws as well as extrusion molding frame members even when the vertical frame members and the horizontal frame members constituted of lightweight shape steels are connected to each other. SOLUTION: While screw through-holes 3a and 3a are formed in the vertical frame members 3A and 3B, cut lines 5a, 5a, etc., parallel to the direction of the width in a row shape at regular intervals in the longitudinal direction of the members are formed in the member end sections of the horizontal frame members 4A and 4B, at the same time, a continuous holding section 5b held between the member end sections and the cut lines 5a and continuous holding sections 5c, 5c, etc., held between the cut lines 5a are successively and alternately made to execute bending operations in an approximately semi-circle arc-shape from the member end sections to one side and the other side to form screw holes 5 with the plate surface of the frame member as the boundary, a screw section 6a of a connection screw 6 passes through from the through holes 3a and 3a formed in the vertical frame members 3A and 3B and, the screw section 6 is screwed into the screw holes 5 formed in the horizontal frame members 4A and 4B to connect.
