However, in Patent Document 1, it is necessary to attach the parting edge main body and the mounting frame to the extent that they can be elastically deformed. When this was used for the eaves ceiling board, it was necessary to take strength measures so that the eaves ceiling board would not come off due to wind pressure. When the eaves-side end of the eaves ceiling plate is restrained and fixed by the restraining metal fitting of Patent Document 2, and the outer wall-side end of the eaves ceiling plate is sandwiched and fixed by the support tool of Patent Document 4, the eaves ceiling plate is fixed. When the eaves side end of the eaves ceiling plate is restrained and fixed by the restraining metal fittings of Patent Document 2 after the outer wall side end is sandwiched between the supports of Patent Document 4, the eaves side end of the eaves ceiling plate and the patent There is a problem that it is difficult to install the eaves ceiling plate on the back of the eaves because it interferes with the portion of the eaves ceiling plate of the restraint metal fitting of Document 2 on which the end on the eaves side is placed.

In order to solve such a problem, it is possible to increase the swallowing portion of the eaves ceiling plate of the support tool of Patent Document 4, reduce the dimension of the eaves ceiling plate in the protruding width direction, and shift the eaves ceiling plate back and forth. In this case, as the finding width of the support tool of Patent Document 4 becomes larger, the design becomes worse, and the support tool becomes larger, so that the cost of parts is also increased. In addition, since the distance from the fastening fulcrum near the wall of the support to the end of the eaves ceiling plate on the outer wall side becomes large, it is disadvantageous in terms of strength, and it becomes necessary to increase the thickness of the support, which increases the weight of the support. As the size increases, the cost of parts is also high.

On the other hand, it is preferable to fix the eaves ceiling board after aligning the joints in a good appearance. There is a problem that the eaves ceiling plate moves and causes misalignment. When a gap for ventilation is provided in the support hardware of Patent Document 3 fitted to the end of the eaves ceiling plate on the eaves side, the joints of the eaves ceiling plate can be neatly stored depending on the construction and the cutting accuracy of the eaves ceiling plate. There is a problem that it is difficult to obtain the ventilation area as designed because the end portion of the eaves ceiling plate is installed so as to interfere with the ventilation gap and the ventilation gap may be obstructed.

The present invention solves the above-mentioned problems, and an object of the present invention is to provide a fixing metal fitting for a face material having excellent construction, designability, strength, maintainability, and breathability.

A typical configuration of the fixing bracket according to the present invention for achieving the above object is a fixing bracket for connecting the face material constituting the ceiling surface to the installation portion of the face material, and is applied to the upper surface of the face material. A first receiving metal fitting provided on the receiving metal fitting, comprising a receiving metal fitting having a first restraining piece that can be contacted and a restraining metal fitting having a second restraining piece that can support and stop the lower surface of the face material. By fitting the fitting portion of the above and the second fitting portion provided on the restraining metal fitting, the restraining metal fitting is slidably engaged with the receiving metal fitting, and the face material is engaged with the first. Until the restraint piece 1 is installed at a position where the upper surface of the face material can be supported and stopped, the restraint fitting can be slid to a position where it does not interfere with the face material and can be retracted. The restraint fitting can be slid to a position where the lower surface of the face material can be supported and stopped by the second restraint piece, and the second restraint piece supports the lower surface of the face material.
