この発明は、例えば自動車車体のピラー等その他の閉断
面構造のメンバー内部に発泡材を形成する方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of forming a foam material inside a member of other closed cross-section structures, such as a pillar of an automobile body.
（従来の技術） 一般に、第２図に示した様な自動車においては。(Conventional technology) Generally, in a car like the one shown in Figure 2.
車体１に第３図に示した様な閉断面構造のメンバー２を

上を図るために、第３図の如く内部空間を比較的硬質の
発泡体（ポリウレタンフォーム）等の発泡材５で満たし
たものもある。A large number of members 2 having a closed cross-section structure as shown in FIG. 3 are used in the vehicle body 1. (Refer to Japanese Unexamined Patent Publication No. 48-2631.) Examples of the member 2 include a front pillar 3 and a center pillar 4 as shown in FIG. 2. Furthermore, in order to improve the strength of the member 2, there is one in which the internal space is filled with a foam material 5 such as a relatively hard foam (polyurethane foam) as shown in FIG.
ところで、上述した発泡材５は１通常、ポリウレタン液

から第４図の如く膨出する。By the way, the above-mentioned foam material 5 is currently currently formed within the member 2 by injecting a polyurethane liquid into the member 2 and foaming it. Moreover, when one foam material 5 is formed in the member 2 by such injection foaming, a part of the foam material 5 is formed in the foam liquid injection hole 9a of the member 2.
It bulges out as shown in Figure 4.
（発明が解決しようとする問題点）
しかしながら、この様な発泡材５の膨出部５ａがあると
、第３図のフィニッシャ−６をメンバー２の孔形成面９
ｂ（メンバー表面）に取り付けることができないという
問題があった。従って、この場合には、膨出部５ａを除
去する作業が必要となり、好ましいものではなかった。(Problems to be Solved by the Invention) However, if there is such a bulging portion 5a of the foamed material 5, the finisher 6 shown in FIG.
There was a problem that it could not be attached to b (member surface). Therefore, in this case, it is necessary to remove the bulging portion 5a, which is not preferable.
また、この様な発泡材５の膨出を防止するために、ウレ
タン液７を第５図の如くメンバー２内に発泡液注入孔９
ａから注入した後に、この発泡液注入孔９ａをテープ８
等で閉成することも行われている。In addition, in order to prevent such swelling of the foam material 5, the urethane liquid 7 is poured into the member 2 through a foam liquid injection hole 9 as shown in FIG.
After injecting from a, tape 8 covers this foaming liquid injection hole 9a.
Closing is also practiced.
尚、メンバー２は断面コ字状の成形パネル９，１０から
構成され、この成形パネル９，１０の両側部に設けたフ
ランジ９ｃ、１０ａは長手方向の複数箇所でスポット溶
接されている。しかも、このフランジ９ｃ。The member 2 is composed of molded panels 9 and 10 having a U-shaped cross section, and flanges 9c and 10a provided on both sides of the molded panels 9 and 10 are spot welded at a plurality of locations in the longitudinal direction. Moreover, this flange 9c.
１０ａ間には微小な隙間（図示せず）も形成されている
が、この隙間は微小であるのため、ウレタン液の注入量
が適正で、その発泡圧力が小さい場合には、発泡材５が
フランジ９ｃ、１０ａ間の隙間からはみだす様なことは
ない。A minute gap (not shown) is also formed between 10a, but since this gap is minute, if the amount of urethane liquid injected is appropriate and the foaming pressure is low, the foamed material 5 will be It does not seem to protrude from the gap between the flanges 9c and 10a.
しかし、ウレタン液７を過注入した場合には、ウレタン
液７の発泡圧力が高くなって、発泡した発泡材５の一部
が発泡時の圧力によりフランジ９ｃ。However, if too much of the urethane liquid 7 is injected, the foaming pressure of the urethane liquid 7 becomes high, and a portion of the foamed material 5 is damaged by the pressure at the time of foaming at the flange 9c.
１０ａ間の隙間から第５図の如くはみ出し部５ｂとして
膨出していた。しかも、この様にはみ出し部５ａが形成
されると見栄えが損われるので、このはみ出し部５ａの
除去作業が必要となり、好ましいものではなかった。As shown in FIG. 5, a protruding portion 5b protruded from the gap between the holes 10a. Moreover, if the protruding portion 5a is formed in this way, the appearance will be impaired, and therefore, it will be necessary to remove the protruding portion 5a, which is not preferable.

を提供することを目的とするものである。Therefore, this invention prevents a part of the foam material formed in a member having a closed cross-section structure from protruding from the joint between panels constituting the member. It is an object of the present invention to provide a method for filling a foam material in which, even if the foam material bulges out, the bulge portion does not interfere with the installation of a finisher.

する。(Effects of the Invention) As explained above, the present invention provides a member having a closed cross-sectional structure in which a communicating hole is formed, and a finisher that covers the communicating hole, and foaming is formed inside the member from the communicating hole. After the liquid was injected, the finisher was used to cover the communication hole so that a gap was formed between the periphery of the communication hole and the surface of the member, and the foaming liquid was foamed. Even if some of the foamed material bulges out from the communicating holes of the member, this bulge will be prevented. This can prevent the part from interfering with the attachment of the finisher to the member. Moreover, this bulging portion is closely fixed to the finisher when foaming and hardening, and the finisher is supported by the member without play.
