Further, the thickness A of the fitting convex portion 62 is slightly larger than or substantially equal to the width B of the fitting groove 56 of the outer portion 5. Two photographing parts 63 are integrally provided on the outer circumference of the sleeve 6.
【００１０】 この実施例における本考案のコード用グロメットは、以上の如き構成からなり 、以下その組み付け方について説明する。 まず、インナー部４の透孔４０にコード３を切れ目４１を介して圧入する。こ のとき、上述のインナー部４の切れ目４１は剃刀等の鋭敏な刃で切断して形成し たものであるから、コード４１を透孔４０にセットした後はインナー部４の弾性 復帰力でその切れ目４１が密着するので、コード３を透孔４０に水密に保持する ことができる。 次に、アウター部５の大径の透孔５２側から爪部５４を乗り越えて中径の透孔 ５１中に上述のコード３を通したインナー部４を圧入する。それから、このアウ ター部５の小径の一端部を車体１の透孔１０に挿入すると共に、そのアウター部 ５の鍔部５５を車体１の透孔１０の縁に当接させる。このとき、アウター部５の 鍔部５５以外の部分の外径は前記車体１の透孔１０の内径より若干小さいので、 上述のアウター部５を車体１の透孔１０に簡単に挿入することができる。The cord grommet of the present invention in this embodiment has the above-mentioned structure, and the assembling method will be described below. First, the cord 3 is press-fitted into the through hole 40 of the inner portion 4 through the cut 41. At this time, since the cut 41 of the inner portion 4 is formed by cutting with a sharp blade such as a razor, after the cord 41 is set in the through hole 40, the elastic restoring force of the inner portion 4 is used. Since the cut 41 is in close contact, the cord 3 can be kept watertight in the through hole 40. Next, the inner portion 4 passing through the cord 3 is press-fitted into the medium-diameter through hole 51 by passing over the claw portion 54 from the large-diameter through hole 52 side of the outer portion 5. Then, one end of the outer portion 5 having a small diameter is inserted into the through hole 10 of the vehicle body 1, and the collar portion 55 of the outer portion 5 is brought into contact with the edge of the through hole 10 of the vehicle body 1. At this time, since the outer diameter of the portion of the outer portion 5 other than the collar portion 55 is slightly smaller than the inner diameter of the through hole 10 of the vehicle body 1, the outer portion 5 described above can be easily inserted into the through hole 10 of the vehicle body 1. it can.
【００１１】 そして、上述のアウター部５の嵌合溝５６にスリーブ６の嵌合凸部６２を圧入 して、締りばめの状態で嵌合させると共に、そのスリーブ６の嵌合筒部６１をア ウター部５の大径の透孔５２に嵌合する。すると、アウター部５の嵌合溝５６と スリーブ６の嵌合凸部６２との締りばめの反力で、図５に示すように、アウター 部５の嵌合溝５６より内側の部分が内側に押圧されて、アウター部５の透孔５１ 中に嵌合したインナー部４を確固に押えることができる。一方、アウター部５の 嵌合溝５６より外側の部分が外側に押圧されて、アウター部５を挿入した車体１ の透孔１０の縁をアウター部５の鍔部５５と共に確固に挟持することができる。 この結果、防水のためのテーピングを施さずに、インナー部４の透孔４０とコー ド３との水密性が確固に保たれ、かつアウター部５の鍔部５５及び外周面と車体 １の透孔１０の縁との水密性も確固に保たれる。しかも、防水のためのテーピン グを施す必要がないので、その分組み付け作業が簡略化され、かつ外観が整然化 される。Then, the fitting convex portion 62 of the sleeve 6 is press-fitted into the fitting groove 56 of the outer portion 5 to be fitted in an interference fit state, and the fitting tubular portion 61 of the sleeve 6 is fitted. It fits into the large-diameter through hole 52 of the outer part 5. Then, due to the reaction force of the interference fit between the fitting groove 56 of the outer portion 5 and the fitting convex portion 62 of the sleeve 6, as shown in FIG. 5, the portion inside the fitting groove 56 of the outer portion 5 is the inner side. The inner portion 4 fitted in the through hole 51 of the outer portion 5 can be firmly pressed by being pressed by. On the other hand, the portion of the outer portion 5 outside the fitting groove 56 is pressed outward, so that the edge of the through hole 10 of the vehicle body 1 into which the outer portion 5 is inserted can be firmly clamped together with the collar portion 55 of the outer portion 5. it can. As a result, the watertightness between the through hole 40 of the inner part 4 and the cord 3 is firmly maintained without applying taping for waterproofing, and the brim part 55 and the outer peripheral surface of the outer part 5 and the transparent part of the vehicle body 1 are protected. Watertightness with the edge of the hole 10 is also firmly maintained. Moreover, since it is not necessary to provide taping for waterproofing, the assembly work is simplified and the appearance is neatly arranged.
【００１２】 特に、この実施例においては、スリーブ６の嵌合筒部６１の高さがアウター部 ５の大径の透孔５２の深さ、すなわちアウター部５の他端面から爪部５４までの 距離より若干大であるので、そのスリーブ６の嵌合筒部６１をアウター部５の大 径の透孔５２に嵌合すると、スリーブ６の嵌合筒部６１の先端がアウター部５の 爪部５４を内側に押圧する。この結果、アウター部５の中径の透孔５１中に締り ばめの状態で嵌合保持されているインナー部４が上述の爪部５４と他方の段部５ ３とによりアウター部５の透孔５０、５１、５２から抜けるのを確実に防ぐこと ができる。In particular, in this embodiment, the height of the fitting cylinder portion 61 of the sleeve 6 is the depth of the large-diameter through hole 52 of the outer portion 5, that is, from the other end surface of the outer portion 5 to the claw portion 54. Since the fitting cylinder portion 61 of the sleeve 6 is fitted into the large-diameter through hole 52 of the outer portion 5, the tip of the fitting cylinder portion 61 of the sleeve 6 is the claw portion of the outer portion 5 because it is slightly larger than the distance. Press 54 inward. As a result, the inner portion 4, which is fitted and held in the medium-diameter through hole 51 of the outer portion 5 in an interference fit state, has the outer portion 5 transparent through the claw portion 54 and the other step portion 53. It is possible to reliably prevent the holes 50, 51 and 52 from coming off.
【００１３】 また、本考案のコード用グロメットは、インナー部４とアウター部５とスリー ブ６との３ピースから構成されるので、図６の（Ａ）、（Ｂ）、（Ｃ）に示すよ うに、車体１の透孔１０の内径Ｄ１、Ｄ２、Ｄ３の大きさが異なったりしても、 アウター部５の中径の透孔５１の内径Ｅを一定にし、かつアウター部５の鍔部５ ５以外の部分の外径Ｃ１、Ｃ２、Ｃ３の大きさを前記車体１の透孔１０の内径Ｄ １、Ｄ２、Ｄ３の大きさに合せておけば、嵌合溝部５５の外径Ｃ１、Ｃ２、Ｃ３ の大きさの異なるアウター部５を何種類かを揃えておくだけで、同一のインナー 部４を共用することができ、その分部品点数が減り、部品管理が容易となる。Further, since the cord grommet of the present invention is composed of three pieces of the inner part 4, the outer part 5 and the sleeve 6, it is shown in FIGS. 6 (A), 6 (B) and 6 (C). Thus, even if the inner diameters D1, D2, D3 of the through hole 10 of the vehicle body 1 are different, the inner diameter E of the medium diameter through hole 51 of the outer portion 5 is made constant, and the collar portion of the outer portion 5 is made uniform. If the sizes of the outer diameters C1, C2, C3 other than 55 are matched with the sizes of the inner diameters D1, D2, D3 of the through hole 10 of the vehicle body 1, the outer diameter C1 of the fitting groove portion 55, The same inner portion 4 can be shared by simply preparing several types of outer portions 5 having different sizes C2 and C3, which reduces the number of components and facilitates component management.
【００１４】 なお、上述の実施例においては、アウター部５の嵌合溝部５５の大径部の端面 に断面三角形状のビード（図示せず）を環状に一体に突設したので、アウター部 ５の嵌合溝部５５を車体１の透孔１０の縁（フランジ部１１）に嵌合した際に、 そのビード５６が車体１に密着するので、さらに水密性が確保される。In the above-described embodiment, since the bead (not shown) having a triangular cross-section is integrally formed on the end surface of the large-diameter portion of the fitting groove portion 55 of the outer portion 5 in an annular shape, the outer portion 5 When the fitting groove portion 55 is fitted to the edge (flange portion 11) of the through hole 10 of the vehicle body 1, the bead 56 thereof is brought into close contact with the vehicle body 1, so that the watertightness is further secured.
【００１５】 なお、上述の実施例においては、リヤーコンビネーションランプ等の車両用灯 具と電源とを結ぶコード３を車体１に開設した透孔１０に水密に通す例について 説明したが、その他のコードを壁に設けた透孔に水密に通すものにも本考案のコ ード用グロメットを使用することができる。In the above-described embodiment, an example in which the cord 3 for connecting the vehicle lamp such as the rear combination lamp and the power source is watertightly passed through the through hole 10 formed in the vehicle body 1 is explained. The cord grommet of the present invention can also be used for the one that is watertightly passed through the through hole provided in the wall.
