O is not filled to every corner of the pillar closed cross-sectional space, and gaps inevitably occur at the corners of the pillar closed cross-sectional space as shown in FIG. In addition, a foamed rubber 11 as a foaming material is also used at the upper end of the front pillar 1, and a thermally foamable rubber sheet lla is attached to the inner panel 3 of the front pillar 1. They are pasted on each inner side of the outer panel 4 as shown by chain lines in FIG. After joining the frame members such as the roof sight rail 5, the inner and outer surfaces are subjected to anti-corrosion treatment, and the outer surfaces are finished and painted, and foamed by heating during the drying process when passing through a coating booth. Since the rubber sheet lla itself does not foam to a large extent, foaming tends to be insufficient for the size of the pillar closed cross-sectional space, and gaps may occur at the corners of the pillar closed cross-sectional space, or the foam rubber 11 may A cavity is created in the center, and these gaps and cavities cannot be seen from the outside. As a result, there was a problem in that even though expensive sound insulation measures were taken, the expected sound insulation effect could not be obtained. Furthermore, as described above, since the thermally foamable rubber sheet lla is also pasted on the inner surface of the outer panel 2 of the front pillar 1, the pasted portion is not subjected to rust prevention treatment, and the outer panel 2 is exposed to the outside of the vehicle. There is a possibility that rust may be raised on the surface of the portion corresponding to the pasting of the rubber sheet Ila. Therefore, the present invention provides an automobile body frame member and its parts that not only significantly improve the sound insulation effect with a simple structure but also increase the rigidity and prevent rust from partially rising on the surface of the outer panel. A manufacturing method is provided.

ができる。Therefore, even in the case of this embodiment, the pillar reinforcement 25 and the flange 28 of the bracket part 26 are close to the inner surface of the rear fender 24, and the rubber sheet 18a foams in this gap to form the foamed rubber layer 18. Therefore, even if a rubber sheet with a small amount of foaming is used, the closed cross-sectional space of the rear pillar 22 will not be able to maintain the pillar reinforcement 25. Since the bracket part 26 and the foamed rubber layer 18 are reliably separated from each other, it is possible to block suspension vibration noise and the like transmitted from the rear wheel house 29 to the closed cross-sectional space of the rear pillar 22. ．．
Since the bracket part 26 is connected to the rear fender 24 via the foamed rubber layer 18, the rigidity of the rear pillar 22 can be further increased, and the tensile rigidity of the rear fender 24, which has a larger closed cross-sectional space inside, can also be ensured. I can do it.

Since it is formed by heating and foaming after the inner surface of the rear fender 24 has been subjected to anti-rust treatment, there will be no non-corrosive treated portion on the inner surface of the rear fender 24.
