To enhance the wind-pressure resistance by providing holes in opposed positions near the opposed edges of a plate glass, mounting a glass support member on the holes, and arranging a reinforcing member on the plate glass by use of the support member.

Circular hole parts are provided near the opposed edges of a plate glass 1 such as reinforced glass, double strength glass float plate glass or the like, or the opposed four corners of the plate glass. Glass support members are mounted on the circular hole parts of the plate glass 1, respectively. Further, reinforcing members 3, 4 are arranged on the plate glass 1 through a cushioning body or elastic washer consisting of hard rubber, hard plastics or the like by use of the glass support members. According to this, the wind pressure resistance can be enhanced.
