より外れる問題があつた。 As described above, the gap between the panel P and the cable 3 is sealed, preventing rainwater from entering.
Moreover, although the cable 3 is supported by the tube 2 without being damaged, as shown in FIG.
When an external force F is applied to the cable 3, the cable 3 is displaced in the direction of the external force F, and the base 1 and the peripheral wall 5
are pulled in the same direction and displaced with deformation, causing the lips 8 and 9 to rise above the panel P, reducing the sealing ability of the panel P. If the lips are pulled further, the base plate 10 of the resin locking member B may Fitting recess 7
I had a more out-of-the-ordinary problem.

ることもない。 In such a state, even if an external force is applied to the electric wire to pull the grommet body, the electric wire is prevented from displacing in the pulling direction by the stopper that is locked to the resin locking member, so the grommet body is pulled by the electric wire and the resin It will not float up or come off from the locking member.
、本考案の実施例を図面を参照して説明する。 Embodiments of the present invention will be described with reference to the drawings.
なお、従来例と同一部品には同一符号を付す。 Note that the same parts as in the conventional example are given the same reference numerals.
第２図に示すように、樹脂製ロツク部材Ｃの基
板１０の内周縁にはヒンジ１４を介して略平板状
の電線接続部１５が一体的に設けられる。 As shown in FIG. 2, a substantially flat wire connecting portion 15 is integrally provided on the inner peripheral edge of the substrate 10 of the resin locking member C via a hinge 14. As shown in FIG.
そして、電線接続部１５のヒンジ１４側の端部
からl1なる距離にストツパー１６を突設する。 Then, a stopper 16 is provided protrudingly provided at a distance l 1 from the end of the wire connecting portion 15 on the hinge 14 side.
このl1なる寸法は樹脂製ロツク部材Ｃの厚さl2
よりも微かに大である。 This dimension l1 is the thickness l2 of the resin lock member C.
It is slightly larger than .
すなわち、ストツパー１６の位置は、電線接続
部１５を第２図に示すような基板１０に直立した
状態から180度回動したときに底壁１２の内周縁
に対して隙間をもつて近接する関係にある。 That is, the position of the stopper 16 is such that it approaches the inner peripheral edge of the bottom wall 12 with a gap when the wire connecting portion 15 is rotated 180 degrees from the state shown in FIG. It is in.
樹脂製ロツク部材Ｃは、第３図に示すように、
２分割されたものを係合突起１７Ａ及び１８Ａを
孔１７Ｂ及び１８Ｂに夫々係合せしめて係脱可能
に組付けられるものであるから、電線接続部１５
を底壁１２方向に垂下した状態で組付けられる。 As shown in FIG. 3, the resin lock member C is
Since the wire connecting portion 15 is divided into two parts and can be detachably assembled by engaging the engaging protrusions 17A and 18A with the holes 17B and 18B, respectively.
It is assembled in a state where it hangs down in the direction of the bottom wall 12.
電線接続部１５の端部には突起１５ａが設けら
れる。 A protrusion 15a is provided at the end of the wire connection portion 15.
その他のグロメツトの構成内容は従来例と同様
である。 The other components of the grommet are the same as in the conventional example.
以上のように構成されたグロメツトによりケー
ブル３をパネルＰにシールするには、第１図に示
すように、グロメツト本体Ａのケーブル２内にケ
ーブル３を挿入し、チユーブ２及びケーブル３を
テープ４にて巻き付ける。 To seal the cable 3 to the panel P using the grommet configured as described above, as shown in FIG. Wrap it around.
次に、グロメツト本体Ａの環状凹部７に樹脂製
ロツク部材Ｃの基板１０を嵌入し、電線固定部１
５とケーブル３とをテープ１７により巻回してケ
ーブル３を電線固定部１５に固着する。 Next, the base plate 10 of the resin locking member C is fitted into the annular recess 7 of the grommet body A, and the wire fixing part 1
5 and the cable 3 are wound with a tape 17 to fix the cable 3 to the wire fixing part 15.
このとき、突起１５ａは電線固定部１５に巻回
され固着されたテープ１７が位置ずれを起して電
線固定部１５より外れることを防止する。 At this time, the protrusion 15a prevents the tape 17 wound and fixed around the wire fixing part 15 from shifting and coming off from the wire fixing part 15.
次に、ロツク部材Ｃの係止片１３をパネルＰの
電線挿入孔に嵌合せしめると係止片の弾性力によ
りグロメツトはパネルＰに係止され、リツプ８及
び９はパネルＰに密着してシールする。 Next, when the locking piece 13 of the locking member C is fitted into the wire insertion hole of the panel P, the grommet is locked to the panel P by the elastic force of the locking piece, and the lips 8 and 9 are tightly attached to the panel P. Seal.

ストツパー１６が底壁１２の内周縁に衝合し、パ
ネルＰに係止された硬質の樹脂製ロツク部材Ｃは
ケーブル３のＦ方向の変位を防止する。 As described above, when an external force is applied from the outside in the direction F to the cable 3 sealed by the grommet and supported in the hole in the panel P, the cable 3 is transferred to the grommet body via the fixed tapes 4 and 17. A and the electric wire fixing part 15 are pulled in the F direction, but the electric wire fixing part 15 is slightly displaced in the F direction, the stopper 16 abuts against the inner peripheral edge of the bottom wall 12, and the hard wire fixed to the panel P is pulled. The resin locking member C prevents the cable 3 from being displaced in the F direction.
電線固定部１５の上記の微かなＦ方向変位量だ
けケーブル３及び軟質のグロメツト本体ＡはＦ方
向に移動するが、その微かな変位量はチユーブ２
と基部１との連ぎの湾曲部の微かな変形によつて
吸収され基板１０と嵌合凹部７との嵌合は確実に
保持される。 The cable 3 and the soft grommet body A move in the F direction by the above-mentioned slight displacement of the wire fixing part 15 in the F direction, but this slight displacement is caused by the tube 2
This is absorbed by the slight deformation of the curved portion connected to the base 1, and the fit between the substrate 10 and the fitting recess 7 is reliably maintained.
従つて、リツプ８及び９はパネルＰに密着した
シール状態を維持し、グロメツト本体Ａが樹脂製
ロツク部材Ｃより離脱する虞れはない。 Therefore, the lips 8 and 9 maintain a sealed state in close contact with the panel P, and there is no risk that the grommet body A will separate from the resin lock member C.

The present invention provides a wire fixing part in a resin locking member, and simply winds the wire fixing part and the cable together to fix them together, which eliminates the conventional problems of reducing the sealing ability of the grommet due to external force and causing the grommet to disassemble. There was no longer any fear of this happening.
しかも、グロメツト本体はケーブルを引張する
外力を受けて無理な変形を生ずることがなくなつ
たため製品寿命を延ばすことができる。 Moreover, the product life can be extended because the grommet body is no longer subject to unreasonable deformation due to the external force of pulling the cable.
