  Next, a method for mounting the fixing member 30 will be described.

  FIG. 5 is an explanatory view showing a state in which the contact member 31 of the fixing member 30 is placed on the peripheral edge portion 51 of the glass plate 50, and FIG. 6 is a state immediately before the fitting member 32 of the fixing member 30 is fitted to the side plate 12. FIG. 7 is an explanatory diagram showing a state where the fitting member 32 of the fixing member 30 is fitted to the side plate 12.

  As shown in FIG. 5, in a state where the contact member 31 of the fixing member 30 is placed on the peripheral portion 51 of the glass plate 50, the fitting portion 321 contacts the protruding portion 123. Since the end portion 322 of the fitting member 32 is separated from the side plate 12 by a dimension corresponding to the protruding height of the fitting portion 321, the fitting member 32 is separated from the side plate 12 so that the end portion 322 is separated from the side plate 12. Tilt. In this state, the second contact surface 312 contacts the peripheral edge 51 of the glass plate 50 via the buffer member 34. In other words, the second contact surface 312 contacts the peripheral edge 51 of the glass plate 50 in a state where the fitting portion 321 contacts the protruding portion 123.

  Next, the fixing member 30 (contact member 31) is pressed in the direction of the arrow shown in FIG. 6 using a finger or palm. That is, in order for the fitting part 321 to fit into the groove part 124, the peripheral part 51 of the glass plate 50 is moved by the contact member 31 so that the fitting part 321 moves over the protruding part 123 and moves to the groove part 124 side. Must be pressed. In this case, since the peripheral edge 51 of the glass plate 50 is pressed in a wide contact range by the second contact surface 312, it is possible to prevent the glass plate 50 from being locally stressed. As shown in FIG. 6, in the state immediately before the fitting member 32 is fitted to the side plate 12, the peripheral portion 51 of the glass plate 50 is pressed by both the second contact surface 312 and the first contact surface 311. .
