【考案の詳細な説明】 〔産業上の利用分野〕 本考案は自動車ワイヤハーネス等の電線群をパネル孔
等の挿通孔部分において保護するためのグロメットに関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a grommet for protecting an electric wire group such as an automobile wire harness at an insertion hole portion such as a panel hole.
〔従来の技術〕 第３図において、グロメットａは比較的軟質の合成樹
脂材より成り、中間に膨出取付部ｂが形成されると共に
膨出取付部ｂの両側に小径の電線支持筒c,dが連設さ
れ、電線支持筒c,d間に拡大された中空室ｅが形成され
ている。[Prior Art] In FIG. 3, a grommet a is made of a relatively soft synthetic resin material, and a bulging mounting portion b is formed in the middle, and a small-diameter wire supporting tube c is formed on both sides of the bulging mounting portion b. d is continuously provided, and an expanded hollow chamber e is formed between the electric wire support cylinders c and d.
膨出取付部ｂにはパネルｆの挿通孔f1に対する環状取
付溝b1が形成され、該環状取付溝b1の一側にパネルｅに
対する衝合鍔部b2、他側に変形鍔部b3が設けられてい
る。The bulging mounting portion b annular mounting groove b 1 for inserting hole f 1 of the panel f is formed, abutment flange portion b 2 on one side of the annular mounting groove b 1 for panel e, deformation flange portion on the other side b 3 is provided.
そして、かかる構造のグロメットａは第４図に示され
る如くに、電線支持筒成形部g1，g2間に膨出された中空
室成形部g3を有する内金型ｇを用いて製造されており、
この場合に内金型ｇの上記中空室成形部g3の径l1を大き
くすると内金型ｇの取り外しが困難になると共に取り外
しの際に電線支持筒ｃが裂けてしまい、歩留まりが悪く
なる欠点があるので、電線支持筒成形部g1の径l2に対す
る中空室成形部g3の径l1を一定限度に押さえる必要があ
り、その結果中空室ｅの内腔が小さくなるに従って変形
鍔部b3の肉厚が大となり、第３図における矢符Ｑ方向か
らグロメットａをパネルｆの挿通孔f1に嵌合する際にお
いて該肉厚が変形鍔部b3の変形を阻害し、装着作業が困
難になる欠点がある。As shown in FIG. 4, the grommet a having such a structure is manufactured by using the inner mold g having the hollow chamber molding portion g 3 which is bulged between the electric wire support cylinder molding portions g 1 and g 2. And
In this case, if the diameter l 1 of the hollow chamber molding portion g 3 of the inner mold g is increased, it becomes difficult to remove the inner mold g and the wire support tube c is torn during the removal, resulting in poor yield. Since there is a defect, it is necessary to keep the diameter l 1 of the hollow chamber molding portion g 3 with respect to the diameter l 2 of the electric wire support cylinder molding portion g 1 to a certain limit, and as a result, the deformation collar becomes smaller as the inner diameter of the hollow chamber e becomes smaller. The thickness of the portion b 3 becomes large, and when the grommet a is fitted into the insertion hole f 1 of the panel f from the direction of the arrow Q in FIG. 3, the thickness hinders the deformation of the deformed flange portion b 3 , There is a drawback that mounting work becomes difficult.
本考案は上記した点に着目して為されたものであり、

金型の引き抜きによる破損をきたすことがない。As described above, the present invention provides the electric wire support cylinder 3 on one side of the cylindrical bulging mounting portion 1 through the tapered connecting cylinder 2.
A hollow chamber bulging between the electric wire support cylinders 3 and 5 by connecting an electric wire support cylinder 5 extending in the opposite direction from the electric wire support cylinder 3 from a middle portion of the connection cylinder 2 through a tapered connection cylinder 4. An annular lightening portion 7 which forms 6 and is open to one side from the inside of the deformed flange portion 1c of the bulging attachment portion 1 along the outside of the tapered connecting cylinder 4
Since the hollow portion facilitates the displacement of the deformed flange portion, the mounting work for the panel hole etc. is speeded up, and the hollow chamber is used to support the electric wire located on the pull-out side of the inner die. Since it can be formed to be relatively small with respect to the cylinder, it is not damaged by pulling out the inner mold.
