It is usually mounted on both sides of the engine, mounted on a frame for bodywork. The conventional sound insulation plate is made of one iron plate or synthetic resin plate. Also,
As disclosed in Japanese Laid-Open Patent Publication No. 57-42292, it is also known that the sound insulating wall has a double structure of an inner wall and an outer wall, and the inside is an empty chamber or the inside is filled with a liquid.

重量増にもなる。(Problems to be solved by the invention) The conventional sound insulation plate has not been sufficiently effective in terms of sound insulation. To improve the sound insulation effect of conventional ones,
It suffices to increase the plate thickness, but this increases the weight, and the synthetic resin product also causes a problem in production such that the molding time becomes long. In addition, in the latter sound insulation wall having a double wall structure, the following drawbacks may occur. In the case where the inside of the double wall structure is empty and the inner and outer walls are formed of thin plates, the walls themselves vibrate and the desired sound insulation effect cannot be obtained. In order to prevent this, it is necessary to increase the thickness of the wall, which causes the same defects as described above. With a double-wall structure with a liquid sealed inside, the sound insulation effect is improved, but it is difficult to keep the liquid sealed and sealed for a long time.
It also increases the weight.

間隔で離隔させた構成としたものである。(Means for Solving the Problems) A sound insulating plate that is erected on the side of an engine, and is a sound insulating plate that is composed of two plates and forms a flat empty chamber inside. A concave bead is provided on one side, and the lower part of the bead is brought into contact with the other plate so that the two plates are separated by a predetermined distance.

The concave bead provided on one of the plates increases rigidity, prevents the plates from resonating and becoming a sound source, and holds the two plates at a predetermined interval for a long period of time.

向上させるためのものである。(Embodiment) FIG. 1 shows an embodiment of the present invention, and FIGS. 2 and 3 show its installation mode. The sound insulation plates 1 are erected on both sides of the engine 2 of the truck so as to be substantially parallel to the side surfaces of the engine, and fixed to a frame 3 for vehicle body structure. The sound insulating plate 1 has a double structure in which two plates, that is, an outer plate 5 and an inner plate 6 made of iron are juxtaposed at a predetermined interval and flanges 5a and 6a are provided on the peripheral edges thereof and are fixed by welding. A flat vacant chamber 7 is formed at.
A convex bead 8 is provided on each of the outer and inner plates 5, 6. Further, the inner plate 6 is provided with a concave bead 9, the lower portion of which is in contact with the counterpart outer plate 5. Convex,
The concave beads 8 and 9 are for improving the rigidity of the outer plate 5 and the inner plate 6.

製法である。FIG. 4 shows another embodiment. The sound insulating plate 11 is made of two synthetic resin plates, that is, an outer plate 15 and an inner plate 16 which are folded back at a peripheral edge 11a and integrally formed, and a flat empty chamber 17 is formed inside. It is an air layer. Also, the inner plate
A concave bead 19 is provided on the lower portion 16, and the lower portion of the bead 19 is in contact with the outer skin 15 of the opponent. The concave bead 19 improves the rigidity of the inner plate 16. The sound insulating plate 11 can be efficiently and easily manufactured by blow molding. That is, between the right and left molds of a predetermined shape, a varistor that hangs in a cylindrical shape is introduced, both molds are sealed to close the lower end of the parison, and the parison is crimped to the mold surface while blowing air into the parison. Is.
