(Fig. 5). Accordingly, two lower groove members 18 and 18 are provided on the left and right of the lower part of the rear surface of the rectangular frame 17 corresponding to the hooks 15 and 15 (see FIG. 5). Further, the lower groove member 18 is provided at a position inside the peripheral edge of the glass surface of the glass plate 6 (see FIG. 5). Therefore, when the glass plate 6 is attached to the rectangular frame 4, neither the hook 15 nor the lower groove member 18 is exposed at the front side and the peripheral edge of the glass surface.

  The arc-shaped upward groove 18a of the lower groove member 18 has a vertical width T1 with which the flange portion 15d of the circular hook portion 15b of the hook 15 can be engaged (see FIG. 7). When the hook portion 15d of the hook 15 is engaged in the upward groove 18a of the lower groove member 18, the vertical movement (stroke) of the glass plate 6 corresponding to the depth (vertical width) T1 of the upward groove 18a. The flange 15d can be engaged in the upward groove 18a (see FIG. 7).

  The lower groove member 18 is attached so as to protrude in the back direction (rear surface direction) with respect to the rear surface 17 ′ of the rectangular frame 17 (FIG. 2B). Therefore, the upward groove 18a is configured to be positioned to protrude rearward from the rear surface 17 '(see FIGS. 2B and 7). On the other hand, the conical hook portion 15b of the hook 15 is flush with the front surface 1 'so that the front end 15d' coincides with the front surface 1 'of the vertical left and right sides 1c and 1d of the rectangular frame 1. The position in the front-rear direction is adjusted (see FIGS. 2B and 7).

  Therefore, the rear surface 17 ′ of the rectangular frame 17 of the glass plate 6 is placed above the flanges 15 d and 15 d of the left and right lower hooks 15 and 15 of the rectangular frame 4, and the upward grooves 18 a and 18 d of the groove members 18 and 18. When the rear surface 17 ′ of the rectangular frame 17 is in close contact with the front surface 1 ′ of the rectangular frame 1 so as to correspond to the front surface 1 ′ of the rectangular frame 1 so as to correspond to each other, the upward groove 18 a of the lower groove member 18. Enters the rear side from the front surface 1 ′ of the rectangular frame 1, and each upward groove 18 a is configured to correspond to the position above the flange portion 15 b of the circular hook portion 15 of the hook 15. . In this state, the lock piece holding portions 23 and 23 are located immediately above the frame-side groove members 22 and 22.

  Therefore, by sliding the glass plate 6 downward (minimum sliding amount T1) in a state where the rear surface of the glass plate 6 is crimped to the front surface 1 ′ from the position, the downward opening of the lock piece holding portion 23 is obtained. 23b and the upper opening downward groove 22b of the frame side groove member 22 can be made to coincide with each other, and the flange portions 15d of the lower hook 15 can be inserted and engaged with the corresponding upward grooves 18a (FIG. 6B).
