0, and the engaging protrusion 32 of the deformation preventing member 30 is engaged with the rectangular hole 41 of the reinforcing plate 40 to engage with the attachment position, and then fixed by the attachment screw 60.

With this structure, for example, even if a large external force is applied to the sash frame 10, the sash frame 10 is less likely to be deformed, so that the sash frame is not only easy to mount but also has improved durability. Further, even when the hinge 80 is attached to the sash frame 10, the sash frame 10 is not deformed by the external force from the hinge 80, so that the sash frame 10 can be permanently and easily used.

Further, when the reinforcing plate 40 is attached to the sash frame 10, the length of the square hole 41 in the width W direction of the sash frame 10 is larger than the length of the engaging projection 32 of the deformation preventing member 30 in the same direction. As a result, the reinforcing plate 4 is attached to the sash frame 10.
The position of the reinforcing plate 40 with respect to the sash frame 10 and the deformation preventing member 30 can be changed in a state where the 0 and the deformation preventing member 30 are temporarily mounted.
