部１３との間で通気が可能となる。The first surface 12 has a width JD = 1.5 mm, which is long in the direction orthogonal to the axis AX (vertical direction in FIG. 2A).
A plurality of slit-shaped through holes 17 (first flow passages) in the axis AX direction (11 in the present embodiment), a predetermined pitch P = 1
Slit row portions 18 arranged in a row of 0 mm and non-hole portions 19 in which the slit-shaped through holes 17 are not arranged are alternately formed. The pitch between the slit row parts 18,
That is, the repeating interval between the slit row portion 18 and the non-hole portion 19 is 220 mm. On the other hand, in the second surface portion 13, a portion other than a portion where the slit-shaped through hole 17 is projected perpendicularly to the second surface portion 13, specifically, not the slit row portion 18, but a portion facing the non-hole portion 19 A relatively large U-shaped notch 20 (second flow passage) is provided.
Therefore, as shown in FIG. 2A, the air that has entered the tubular portion 11 from the first surface portion 12 side through the slit-shaped through hole 17 moves in the tubular portion 11 along the axis AX direction. Then
It moves to the outside of the second surface portion 13 through the notch 20.
As described above, in the metal product 10, ventilation can be performed between the first surface portion 12 and the second surface portion 13.

Since the notch 20 is not formed in the portion corresponding to 17, the flame and rainwater hit the second surface portion 13. Therefore, it is possible to prevent the flame or rainwater from directly entering the ventilation layer or the like in the outer wall through the notch 20. Further, the dew condensation water generated in the ventilation layer and the invading rain water can be discharged through the notch 20 and the slit-shaped through hole 17 of the metal object 10. The width JD of the slit-shaped through hole 17 is narrowed to 1.5 mm in order to prevent insects and dust from entering the tubular portion 11 and the outer wall through the slit-shaped through hole 17 as much as possible, and This is to prevent the inside of the metal fitting 10 from being seen from the outside after mounting.

Folding line 3 that exceeds 32 and becomes the third surface portion 14
It extends to the area surrounded by 2 and 31. Therefore, after the bending process, as shown in FIG. 2A, a 1-3 enlargement that extends beyond the 1-3 corner portion 24 formed by the first surface portion 12 and the third surface portion 14 and extends to the third surface portion 14 The part 17A is formed. Further, the slit-shaped through-hole 17 goes beyond the fold line 33 and becomes the fourth surface portion 15 and the fourth surface extension portion 16 and the fold line 3
It extends to a region outside 3 (upward in the drawing).
Therefore, after the bending process, as shown in FIG.

It extends to the area surrounded by and 31.
Therefore, after the bending process, as shown in FIG.
A 2-3 enlarged portion 20 </ b> A that extends to the third surface portion 14 beyond the 2-3 corner portion 26 formed by the second surface portion 13 and the third surface portion 14 is formed. Further, the width of the region outside (the lower side in the drawing) of the fold line 31 which becomes the second surface portion 13 is made smaller than the width of the region surrounded by the fold lines 32 and 33 which becomes the first surface portion 12. That is, in the metal fitting 10, the width W1 of the first surface portion 12
The width W2 (= 11 m) of the second surface portion 13 is larger than (= 13 mm).
m) is reduced so that a gap 27 is formed between the second surface portion 13 and the fourth surface portion 15. The gap 27 can absorb the distortion of the metal fitting 10 or the building. The reason why the 2-3 enlarged portion 20A is formed in this way will be described later.
