る等の問題がある。2. Description of the Related Art Sound insulation plates are installed along roads and railways for the purpose of isolating noise from vehicles. Some of such sound insulating plates are formed of a light opaque sound insulating plate such as PC concrete or metal, but those formed of a light opaque sound insulating plate have excellent sound insulating properties, but are installed on an elevated road. In this case, there is a problem in that the weight becomes heavy in relation to the foundation serving as a base portion, and the surrounding scenery is obstructed by the opacity, so that there is a feeling of oppression and the scenery is poor.

ち、歪みやすい問題がある。Therefore, in recent years, in order to reduce the weight and to prevent the surrounding scenery from being obstructed, a sound insulating plate formed of a synthetic resin plate such as polycarbonate having a light transmitting property has recently been developed. It is being used for wealth. Conventionally, as such a light-transmitting sound-insulating plate, there is a light-transmitting sound insulating plate in which a light-transmitting plate is attached to a front surface of a frame framed in a rectangular shape by a metal frame material having an L-shaped cross section. However, when the light-transmitting plate is bolted to the front of the metal frame, the light-transmitting plate expands and contracts because the metal frame and the light-transmitting plate have different coefficients of thermal expansion. There is a problem of undulation and distortion.

のである。Therefore, as shown in FIG. 3, an end of a light transmitting plate d having a retaining member c is inserted and held in an opening a of a long frame member b having an opening a along the length direction. By doing so, there has been proposed a sound insulating plate that prevents the light transmitting plate d from waving or distorting due to expansion and contraction, and prevents the light transmitting plate d from falling off. That is, in this sound insulating plate, the frame member b is integrally formed by aluminum extrusion, and the opening a is
