A field edge receiver U is attached via H, a field edge N is locked to the field edge receiver U via a clip C, and a ceiling material T such as a ceiling board is attached to the field edge N with screws or an adhesive. It is intended to be installed horizontally by

  In the embodiment shown in FIG. 11, a wooden ceiling frame made of square members supported on the upper surface of the H-shaped steel 20 which is a steel-made roof frame provided to be inclined in the longitudinal direction in accordance with the gradient of the roof material L. 1 is fixed to a wooden purlin 10, which is composed of a fixed bracket 4 and a movable bracket 6, by a fixing screw 19 (wood screw 19 d).

  Then, a movable metal fitting that is caulked and fixed around a pivot shaft 5 with respect to the fixed metal fitting 4 that is fixed to the wooden purlin 10 made of square wood, which is the wooden ceiling housing 10, by a fixing screw 19 (wood screw 19d). 6 is loaded with an external force against the caulking stop force using an appropriate work tool, and the movable metal fitting 6 is positioned in a suspended state in a vertical plane perpendicular to the pivot shaft 5 as shown in the figure. The long suspension bolt 7a for hanging the edge receiving member is suspended in the vertical state by the tap screw hole 16a or the double nut 16b as shown in the arrow at the screwing portion 16 of the screwing piece 14 of the screw. A field edge receiver U is attached to the lower end of the suspension bolt 7 via a hanger H, and the field edge N is locked to the field edge receiver U via a clip C in a crossed state. By attaching the ceiling material T Regardless of the inclination angle how roofing L and steel roofing bone frame 20 which is this mounted in parallel, in which to be able to attach the ceiling material T horizontally.

  As described above, according to the present invention, the fixed metal fitting 4 and the movable metal fitting 6 that is caulked to the pivot metal shaft 5 are formed. The movable metal fitting 6 is centered on the pivot metal shaft 5 with respect to the fixed metal fitting 4. A short suspension bolt 7 or a field that is formed so as to be able to swing from a suspended state to a position in which it swings to the left and right and that is attached to the movable metal fitting 6 and that is attached to the movable bracket 6 and that is connected to the bracing brace 17. Whether it is a long suspension bolt 7a for suspending the edge receiver U, it can be used for steadying regardless of whether the ceiling housing 1 to which the field edge suspension bracket 3 is attached is horizontal or inclined. The brace 17 or the ceiling material T can be easily attached.
