No. -291206. In this case, a foamable base material is mounted on a foamable restriction holder that is mounted orthogonal to the longitudinal direction of the hollow chamber of the hollow body. Then, when the foamable base material is foamed by external heating, the foaming direction is restricted by the holder, whereby the foaming of the foamable base material in the direction perpendicular to the longitudinal direction of the hollow chamber is promoted. Thus, the hollow chamber is efficiently blocked by a small amount of the foamable base material.

In this case, if the hollow chamber of the hollow body is blocked by the blocking structure, the drain hose cannot be inserted, so that the blocking structure cannot be implemented. For this reason, as shown in FIG. 7, the foamable base material attached to the holder 110 foams to form a foam 122, and after the hollow chamber 106 of the hollow body 101 is shut off, the drain hose is inserted into the hollow chamber 106. By inserting an insertion hole 125 for inserting the drain hose 108 through the holder 110 in advance, the hollow body 101 into which the drain hose 108 is inserted is inserted.
Can be implemented with a blocking structure.

When the diameter of the insertion hole 125 is increased, the blocking performance of the hollow chamber 106 is deteriorated. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to make the hole diameter of an insertion hole of a holder as small as possible and to secure a blocking property.
An object of the present invention is to provide a shielding structure for a hollow body of a vehicle in which an end of an insertion material such as a drain hose can be easily inserted into the insertion hole.

Thereafter, when an insert such as a drain hose is inserted into the insertion hole of the support plate, the insert is inserted from one longitudinal side of the hollow chamber of the hollow body, and the end of the insert is inserted into the support plate. It is advanced toward the side. And
The end of the insert is guided by contacting the guide means of the support plate, and is inserted into the insertion hole of the support member. In this manner, the end of the insert is inserted into the insertion hole while being guided by the guide means of the holder, so that the diameter of the insertion hole is substantially the same as the outer diameter of the insert. Even if it is as small as possible, the insertion material can be easily inserted into the insertion hole.

に発泡膨張され、発泡体２２となる。As described above, the holder 1 is attached to the inner panel 2.
After the foamable base material 21 is held by 0, the inner panel 2 and the outer panel 4 are spot-welded at their mutual flanges 3 and 5 to form a front pillar 1 having a hollow box-shaped closed cross section. . Thereafter, the vehicle body having the front pillar 1 is immersed in a paint tank. At this time, the paint also flows into the hollow chamber 6 of the front pillar 1, and the paint adheres to the inner peripheral wall surface of the front pillar 1. At this time, the paint flowing into the hollow chamber 6 of the front pillar 1 flows through the insertion hole 25 of the support plate 11 of the holder and the gap between the holder 10 and the inner peripheral wall surface of the hollow chamber 6. The paint adheres well to the inner peripheral wall surface. After the vehicle body is immersed in the paint tank and pulled up as described above, the foamable base material 21 is heated by external heating, for example, by external heating during baking of the vehicle body having the front pillar 1. As shown in FIG. 4 and FIG.

６が効率よく遮断される。When the foamable base material 21 is foamed and expanded,
Since the left and right both sides of the foamable base material 21 are supported while being sandwiched by the pair of support plates 11 of the holder 10, the foamable base material 21 is held in the longitudinal direction of the hollow chamber 6. Foaming expansion is limited, and foaming expansion of the foamable base material 21 is effectively promoted in a direction orthogonal to the longitudinal direction of the hollow chamber 6. Then, the peripheral portion of the foam 22 due to the foaming expansion of the foamable base material 21 is securely and satisfactorily adhered to the inner peripheral wall surface of the hollow chamber 6. As a result, the hollow space 6 is efficiently shut off by the foam 22 due to the foaming expansion of the foamable base material 21 in a small amount.

易にかつ手早く行われる。As described above, after the hollow chamber 6 of the front pillar 1 is blocked by the foam 22 due to the foaming expansion of the foamable base material 21 attached to the holder 10, as shown in FIG. A drain hose 8 is inserted from above the hollow chamber 6 of the pillar 1. When the end portion (lower end portion) of the drain hose 8 reaches the substantially tapered guide portion formed by the guide pieces 32 of the holder 10, the guide hole is then guided by the guide portion into the insertion hole 25 of the holder 10. Be included. Therefore, the hole diameter of the insertion hole 25 of the holder 10 is
The drain hose 8 can be easily and quickly inserted into the insertion hole 25 even if it is made as small as possible so as to be substantially the same as the outer diameter of the drain hose.

とができる。As described above, according to the first aspect of the present invention, the hole diameter of the insertion hole of the holder is made as small as possible to secure the blocking property while the insertion material such as the drain hose is inserted. Since the end portion can be easily inserted, the effect is large as a blocking structure of the hollow body into which the insertion material is inserted. According to the second aspect of the present invention, it is not only possible to eliminate the necessity of separately forming and assembling the guide means with respect to one side surface of the holder, but also to realize the rigidity of the holder by a large number of guide pieces. By increasing the height, the blocking performance of the hollow body can be improved.
