The length d2 in the width direction to the outer surface of the frame 51 is formed to be at least longer than the thickness of the frame 51.

Further, in the present embodiment, the length d2 is shorter than the length D2 from one outer surface of the frame 51 shown in FIG. 3 to the other inner surface. As a result, when the support portion 72 is inserted into the inserted portion 51b of the frame 51, rubbing between the second support arm 77 and the inner surface of the frame 51 can be suppressed. Further, since the second support arm 77 extends parallel to the longitudinal direction and extends in a long length, the fastener 7 can be attached to the outer wall panel 5 by simply inserting the second support arm 77 along the frame 51. It can be attached to 5, and the attachment work can be performed smoothly.

Further, as shown in FIG. 2A, in the depth direction, the fixing portion 73 of the supporting portion 72 protrudes outward by the length d3. It is desirable that the protruding length d3 be the same as or slightly longer than the thickness of the frame 51. As a result, even if the second support arm 77 is inserted into the inserted portion 51b, the fixing portion 73 can be brought into contact with the stud 4 as shown in FIG. 3 without being affected by the thickness of the frame 51. it can.

Further, as shown in FIG. 2B, the fixed portion 73 has a recessed bottom portion on the side opposite to the insertion side into the frame 51 in the length direction, and the fixed portion 73 is more fixed than the pair of side wall portions 74. 73 is formed shorter by the length d4. With this configuration, when the frame 51 is fastened to the stud 4 with the fastener 7, the outer wall panel 5 is placed between the installation portion 9 and the fixing portion 73 such as the floor beam 32 and the upper surface of the ceiling beam 31 indicated by the alternate long and short dash line. A communication port S1 that communicates between the outside and the inside is formed.

Further, the communication port S1 communicates with the flow passage S2 formed by the studs 4 and the frames 51 and 51. Therefore, moisture and moisture inside the outer wall panel 5 can be released to the outside through the flow passage S2 and the communication port S1, and dew condensation inside the outer wall panel 5 can be prevented.

The fastening metal fitting 7 is limited to the configuration of the present embodiment as long as it has a fastening main body 71 having an elongated hole 75 and a support portion 72 inserted into the frame 51 to support the fastening main body 71. There is no. Further, the manufacturing method of the fastening metal fitting 7 is not limited.
