板が枠体からはずれやすい問題点がある。(Problems to be Solved by the Invention) However, since the metal frame and the transparent resin plate are bolted to each other in the light-transmitting soundproof plate of FIGS. 6 and 7, the metal frame and the transparent resin plate are not fixed. Because the expansion and contraction rates are different, the transparent resin plate expands and contracts, causing a problem that the transparent resin plate is wavy and easily distorted. Further, the light-transmitting soundproof plate shown in FIGS. 8 and 9 has a problem that the transparent resin plate is easily detached from the frame when an external force such as a wind load is applied to the plate.

れるようなことがない。(Effects of the Invention) As described in detail above, the light-transmitting soundproof plate of the present invention is formed by forming a metal frame material having an opening along the length direction into a square shape with the opening inside. In the frame, a transparent resin plate is held with its peripheral edge inserted into the opening of each frame material, and the entrance of the opposing frame material is narrowed by the opposing opening edge. In each of the two opposite edges of the transparent resin plate, a projection is provided over the entire length on the outer wall near each edge or the edge by integral molding with the transparent resin plate. The dimension between the bottoms of the transparent resin plates is made larger than the dimension between the opposing edges having the projections of the transparent resin plate, and the dimension between the inner walls of the openings facing each other between the opposing surfaces of the opposing projections of the transparent resin plate. The protrusion is loosely fitted into the dovetail-shaped opening and Since the transparent resin plate expands and contracts, the distortion can be absorbed by the play between the projection and the opening, so that the transparent resin plate is not distorted and the transparent resin plate is It does not impair the aesthetic appearance by undulating as a whole, and eliminates the irregular reflection of light due to the undulation phenomenon of the transparent resin plate, thereby preventing adverse effects on the vehicle driver and is useful in traffic safety. Moreover, the transparent resin plate does not easily come off under wind load and impact load.

てやすい。In addition, since the protruding portion is provided integrally with the transparent resin plate on the outer wall near each edge or near the edge at two opposing edges of the transparent resin plate, the protruding portion serves as a reinforcing rib. As a result, the rigidity can be imparted to the transparent resin plate by the reinforcing effect, and the transparent resin plate itself can be provided with flatness without warping or bending, so that the transparent resin plate undulates during use of the soundproofing plate and impairs aesthetic appearance. There is nothing. In addition, since the protrusion for retaining is integrally formed when the transparent resin plate is formed, there is no need to separately attach a retaining member or the like to the transparent resin plate, and the assembly is easy.
