Since the expansion and contraction rates of the transparent resin plates are different, there is a problem that the transparent resin plate is easily distorted due to expansion and contraction. Furthermore, in the case of the translucent soundproof boards shown in Figures 5 and 6, the transparent resin board tends to come off from the frame when a load is applied to the board, and is hardly ever put into practical use. Because of this, there is a problem in that the transparent resin plate is likely to be wavy, distorted, or bent as a whole.

つ。(Effects of the invention) As detailed above, the translucent soundproof board of the present invention has transparent resin plates inserted into the frame with their peripheral edges inserted into the openings of each frame member, and is held in pairs on the upper and lower or left and right sides. In the frame material, both edges of the transparent resin plate are locked by the locking protrusions against the rebound resilience of the plate, and the transparent resin plate is curved in an arc shape between the pair of frame members. The transparent resin plate is not distorted due to expansion and contraction, and the transparent resin plate does not become wavy as a whole and spoil its aesthetic appearance. Moreover, it eliminates the diffused reflection of light caused by the waving phenomenon of the transparent resin plate, and prevents the adverse effects of this diffused reflection on vehicle drivers, contributing to traffic safety.
