Description of the Related Art Conventionally, a structure having a foamable base material made of a material that is foamed by external heating and a support member for supporting the foamable base material at a required position in a hollow chamber of a hollow structure. Foam fillers for hollow structures are known. In this type of foam filling device, in order to effectively block the hollow chamber, it is necessary to suppress foaming of the foamable base material in the longitudinal direction of the hollow chamber and to cause the hollow chamber to be substantially orthogonal to the longitudinal direction, that is, the inner circumference of the hollow chamber. It is desired to promote foaming in the direction towards the wall.
For this reason, there is known a structure in which a supporting member is provided with a supporting plate that is substantially orthogonal to the longitudinal direction of the hollow chamber and supports one side surface of the foamable substrate. Further, the size of the support plate is appropriately set so that a predetermined gap is formed between the inner wall surface of the hollow chamber and the inner wall surface of the hollow chamber so as not to hinder the flow of the paint.

And FIG. 6). In this way, the foaming of the foamable base material 30 is suppressed by the support plate 12 in the longitudinal direction of the hollow chamber 6, and in the direction substantially orthogonal to the longitudinal direction, that is, in the direction toward the inner peripheral wall surface of the hollow chamber 6. By being promoted to become the foam 35, the hollow chamber 6 is efficiently blocked. Further, due to the annular weir wall 14 of the support plate 12, the foamable base material 30 is

Therefore, it is possible to prevent (reduce) a part of the foam 35 from passing over the annular weir wall 14 and flowing into the inner space 12a. by this,
Poor filling of the foam 35 into the hollow chamber 6 can be prevented. As a result, the peripheral edge portion of the foamed body 35 adheres to the inner peripheral wall surface of the hollow chamber 6 without any gap, whereby the hollow chamber 6
Can be blocked well. In particular, the foamable substrate 30
Where a is the thickness dimension, n is the foaming ratio of the foamable base material 30, and b is the height dimension of the annular weir wall 14, b≈n
The relationship is set to 1/3 × a. For example,
When the expansion ratio of the foamable base material 30 is 8, the height dimension b of the annular weir wall 14 is set to be about twice as large as the thickness dimension a of the foamable base material 30. Further, when the foaming ratio of the foamable base material 30 is 27 times, the height dimension b of the annular weir wall 14 is set to be about 3 times larger than the thickness dimension a of the foamable base material 30. In this way, by setting the height dimension b of the annular weir wall 14, the foam 3
It is possible to surely prevent a part of 5 from overcoming the annular weir wall 14 and flowing into the inner space 12a. As a result, the peripheral edge of the foam 35 is reliably bonded to the inner peripheral wall surface of the hollow chamber 6 without any gap. Then, the foam 35 can surely block the hollow chamber 6 of the hollow panel 1 to favorably perform sound insulation and vibration damping.
