PROBLEM TO BE SOLVED: To provide a beam installing metal fitting of a boundary wall stud frame in a boundary wall part of an attic space capable of reducing the burden of a worker by simple construction work. SOLUTION: In a boundary wall part of an attic space by sticking a wall material to both sides of a roof truss via a boundary wall stud frame, and in the boundary wall stud frame, the horizontal part 3a2 is fixed to a beam 23 of the roof truss composed of inverse T-shaped shape steel by a beam installing metal fitting 5, and a principal rafter part is fixed by a principal rafter part installing metal fitting by sandwiching the principal rafter part of the roof truss. In the beam installing metal fitting 5, a lower end part is formed as a sandwiching part 51 freely insertable from above into a rising part 23a of the beam 23, an upper end part is formed as a horizontal part 53 bent in a hook shape, and a beam installing hole 54 for fixing the horizontal part 3a2 of the boundary wall stud frame by a fastening/installing means is formed in this horizontal part 53.
