In this state, the long second glass is held from the slit 613 into the gap S1 formed between the long plate portion 65b side of the leaf spring 65 protruding from the slit 613 and the U-shaped flat surface 612d. The protrusion 64 of the metal fitting 621 is inserted. Specifically, the long side portion 64a of the protruding portion 64 is inserted between the long plate portion 65b side of the leaf spring 65 and the U-shaped plane 611d. Then, the leaf spring 65 is elastically deformed so that the long plate portion 65b and the short plate portion 65a approach each other, and the projecting portion 64 enters deeply into the L-shaped side surface 612c of the long first glass holding metal 611.

  When the long second glass holding metal fitting 621 is moved downward with the long plate portion 65b and the short plate portion 65a of the leaf spring 65 approaching each other, as shown in FIG. It moves to the narrow part 613b below the slit 613. When the protruding portion 64 moves downward, the long plate portion 65b and the short plate portion 65a return to the original state due to the restoring force of the leaf spring, and the state in which the space between the long plate portion 65b side and the U-shaped plane 611d is urged. Then, the wide portion 613a is closed. By attaching the long second glass holding fitting 621 to the long first glass holding fitting 611, the first surface 622a of the long second glass holding fitting 621 and the long first glass holding fitting 611 are provided. The glass 51 is clamped by the L-shaped side surface 612c, and the glass 51 is held (see FIG. 6). Thereafter, the glass 51 is attached to the window frame 30 by the outer pressing edge 70. In this state, the long second glass holding metal fitting 621 cannot be pulled out from the outdoor side and is locked.
