As shown in FIG. 7, one preliminary bent portion 16c may be provided in the connecting portion 16, or a plurality of preliminary bent portions 16c may be provided in the connecting portion 16 as shown in FIG. May be good). Such a pre-bending portion 16c can also guide the bending of the connecting portion 16 so that the first and second fixing plates 10 and 13 are close to each other.

  According to such a starter fitting 1, the through hole 16 a, the thin-walled portion 16 b, or the preliminary bent portion 16 c that guides the bending of the connecting portion 16 so that the first and second fixing plates 10, 13 are brought close to each other are connected to the connecting portion 16. Since it is provided, the first and second fixing plates 10 and 13 can be fixed to the two surfaces 100a and 100b of the wall base material that meet at the corner of the building by bending the connecting portion 16, respectively. Thereby, the shift | offset | difference of the height position of the starter metal fitting which arises in the corner of a building can be reduced by connecting other starter metal fittings to the starter metal fitting 1 attached to the corner.

  Moreover, since the side ends 11d and 14d of the first and second lower flanges 11 and 14 constitute the open side end of the starter fitting 1, the first and second lower flanges 11 and 14 of the corner starter fitting 1 are used. And the lower flange of the straight starter fitting can constitute a continuous lower flange, and the deviation of the height position of the starter fitting can be more reliably reduced.

  Further, since the connecting portions 16 of the plurality of starter fittings 1 are bent in accordance with the angles of the two surfaces 100a and 100b of the wall base material 100 that meet at a plurality of corners of the building, they are widely used at various corners of the building.
