As shown in FIG. 1, the upper frame 10, the lower frame 11 and the vertical frame 12 are designed to have a small edge clearance 18 and to have as small a width as possible.

The fitting frame 1 is in the form of a horizontally long rectangle whose horizontal dimension is larger than its vertical dimension, and is therefore susceptible to deformation of the skeletons 8a and 8b due to shaking (particularly lateral shaking) of an earthquake. Therefore, in this fitting, even if the frames 8a and 8b are deformed (displaced) by receiving a large load due to an earthquake, the upper part of the fitting frame 1 is connected to the frame 8a so that the fitting frame 1 does not deform and the glass 13 does not break. The upper bracket 2 is provided with a mechanism for absorbing the displacement of the frame 8a.

As shown in FIG. 2, the upper bracket 2 is provided across the upper parts of the fitting frames 1, 1 adjacent to each other on the left and right. It has a skeleton attachment portion 4 and a slide portion 5 that connects the fitting frame attachment portion 3 and the skeleton attachment portion 4 .

Further, the slide portion 5 is slidable relative to the frame attachment portion 4 in the in-plane direction (vertical direction) perpendicular to the edge of the fitting frame 1 . As a result, even if the upper frame 8a is displaced in the horizontal direction and the vertical direction with respect to the lower frame 8b during an earthquake, the upper bracket 2 can absorb the displacement. The amount of displacement that can be absorbed is approximately 30 mm in the right and left directions, and approximately 15 mm in the upward and downward directions.

As shown in FIGS. 1 and 2, the lower bracket 9 fixes the lower part of the fitting frame 1 to the lower skeleton 8b so as not to move.

FIG. 4 shows a state when an earthquake occurs and the building frame 8a on the upper side of the fitting frame is displaced rightward and upward with respect to the building body 8b on the lower side. As shown in the figure, in this fitting, when the skeleton 8a is displaced in such a manner, the sliding portion 5 slides in the in-plane direction along the edge of the fitting frame 1 and also slides in the plane perpendicular to the edge of the fitting frame 1. Since the displacement of the frame 8a can be absorbed by sliding in the direction, deformation of the fitting frame 1 can be prevented, and breakage of the glass 13 can be prevented. Since the sliding part 5 is structured to slide by the vertical and horizontal guide members 22, 26 and the bearings 23, 30 arranged around them, it can be slid smoothly without resistance and can instantly follow the displacement of the frame 8a.
