[Second embodiment]
Next, a second embodiment of the present invention will be described. In the second embodiment, the same functional components as those in the first embodiment will be described. The same reference numerals as in the first embodiment denote the same parts, and a detailed description thereof will be omitted.

  In the second embodiment, a mounting bracket 80 as a sash mounting bracket is used instead of the mounting bracket 48 of the first embodiment. 4A is a perspective view of the mounting bracket 80, and FIG. 4B is a cross-sectional view of a main part of the outer wall 12 on which the mounting bracket 80 is provided, as viewed from above. Have been.

  The mounting bracket 80 is provided with a support plate 82 instead of the support plate 52 as a frame support member, and the support plate 82 extends from the base 50 </ b> A of the base 50. The support plate 82 of the mounting bracket 80 is provided with a pair of restriction plates 84 as restriction portions. The restriction plate 84 is closer to the indoor side than the leg plate 54 on the surface of the support plate 82 on the leg plate 54 side. Is provided in the part. The limiting plate 84 is protruded from both ends in the width direction of the supporting plate 82, and has a substantially triangular flat plate shape in which a corner on the leg plate 54 side is substantially a right angle.

  When the leg plate 54 is fitted to the flange 34A of the base material 34, the indoor flange 34A is inserted between the restriction plate 84 and the leg plate 54. At this time, the end surface 84A of the restriction plate 84 on the leg plate 54 side is opposed to the flange 34A of the base material 34 so as to be able to abut.

  As shown in FIG. 4B, the mounting bracket 80 is fixed to the base material 34 by fitting the leg plate 54 between the flanges 34 </ b> A of the base material 34. The restriction plate 84 of the mounting bracket 80 is disposed on the indoor side of the base material 34, and the end surface 84A faces the outdoor surface of the flange 34A of the base material 34.

  When the fixing screw 66 is screwed from the vertical frame 40 of the sash frame 36, the supporting plate 82 of the mounting bracket 80 is supported by the tip of the fixing screw 66 using the tip of the indoor side flange 34 </ b> A of the base material 34 as a fulcrum. It is pressed in the direction of displacement (displacement due to elastic deformation) in the direction away from it.

  Here, in the mounting bracket 80, an end surface 84 A of the limiting plate 84 in which the indoor side of the support plate 82 is pressed by the fixing screw 66 and the support plate 82 tends to be elastically deformed comes into contact with the flange 34 A of the base material 34. Thus, the limiting plate 84 limits the displacement of the support plate 82 due to the elastic deformation. Therefore, in the mounting bracket 80, since the displacement due to the elastic deformation of the support plate 82 is limited, the fixing screw 66 is not inclined and screwed to the support plate 82. Moreover, since the mounting bracket 80 sandwiches the flange 34A of the base material 34 between the leg plate 54 and the restriction plate 84, the vertical frame 40 of the sash frame 36 can be fixed to the base material 34 in a stable state.

  In addition, it is conceivable that the mounting bracket 80 is displaced so that the base 50 is lifted by pressing the support plate 82 side. Also in this case, since the end surface 84A of the limiting plate 84 of the support plate 82 contacts the flange 34A of the base material 34, the displacement of the mounting bracket 80 such that the base 50 rises from the base material 34 is limited.

  In the second embodiment, the mounting bracket 80 in which the mounting plate 48 is provided with the limiting plate 84 as a limiting part has been described as an example, but the limiting unit may be provided on the mounting bracket 70. . In this case, as the configuration in which the holding portion 74 holds the outdoor-side flange 34A of the base material 34, the support plate 72 is projected from the indoor-side flange 34A of the base material 34 to the indoor side. The limiting plate 84 may be provided on the support plate 72 at a portion protruding from the base material 34 toward the indoor side. Accordingly, also in the mounting bracket 70, the displacement of the support plate 72 due to elastic deformation or the like can be restricted by the fixing screw 66 for fixing the vertical frame 40.

  Further, the limiting portion 84 has been described as an example of the limiting plate 84 having a substantially triangular flat plate shape, but the limiting portion is not limited to this. The restricting portion may have an arbitrary shape in which a protrusion having a shape capable of contacting the indoor surface of the flange 34A of the base material 34 is provided.

  Further, in the first and second embodiments described above, the grooved steel is used as the base material 34 of the base frame 32. However, the base member is not limited to the grooved steel, but is an angle steel (L-shaped steel), an H-shaped steel. Alternatively, a steel material having an arbitrary shape such as a lip grooved steel can be applied, and the base may be formed according to the shape of the steel material to be applied. Further, the base member is not limited to steel, but may be another member such as wood.
