PROBLEM TO BE SOLVED: To manufacture variously dimensioned groove-shaped assembly with a usual bending tool and provide economical products by dividing a groove member into a member with angular section and a member with linear section to be molded and combined with each other. SOLUTION: A groove-shaped assembly 4 is composed of a member 10 with angular section worked by the bending molding or the like of a metal plate and a member 20 with linear section. The member 10 with angular section is formed with a suspending edge 12 suspending from one side end of a top plate part 11 and a bent edge 13, while being formed with a first side plate part 14 suspending from the other side end, and a lower part horizontal edge 24, rising edge 25 and folded-back edge 26 are sequentially established on the lower end. The member 20 with linear section is formed with a lip edge 22 suspended from one side end of a horizontal edge 21, while a second side plate part 23 suspended from the other side end is formed and a lower part horizontal edge 24, rising edge 25 and folded-back edge 26 are sequentially established on the lower end. And the member 10 with angular section is joined with the member 20 with linear section by a screw 18 in a piled connection part 27 to form the groove-shaped assembly 4. |
