While pulling the one end toward the passenger compartment R, the other end is elastically deformed and pushed through the hole 6a. Thereafter, the cylinder body 31 disposed in the passenger compartment R is pulled to lock the locking recess 21 of the grommet body 2 in the hole 6a as described above, and the grommet 1 is attached to the panel 6 as shown in FIG. Attach to.

このグロメット1に、エンジンルームE内に配された第二の筒状部4からワイヤハーネス7を通していく。そして、車室R側からスリット32の長手方向中央を広げてワイヤハーネス7を車室R内に引っ張り込み、スリット32の長手方向両端側をそれぞれ広げて筒部本体31内にワイヤハーネス7を通す。ワイヤハーネス7は、筒状部3によって二方向に導出される。   The grommet 1 is passed through the wire harness 7 from the second cylindrical portion 4 disposed in the engine room E. Then, the longitudinal center of the slit 32 is widened from the passenger compartment R side and the wire harness 7 is pulled into the passenger compartment R, and both ends of the slit 32 in the longitudinal direction are widened and the wire harness 7 is passed through the tubular body 31. . The wire harness 7 is led out in two directions by the cylindrical portion 3.

そして、カバー部33を折り曲げて幅狭部34でスリット32の長手方向中央を覆う。図3に示すように、幅広部35の基端から先端に向かって幅広部35の端部と筒部本体31の端部とに粘着テープ5を巻き付けてカバー部33を固定するとともに粘着テープ5でスリット32の長手方向両端を覆い、続けて筒部本体31から導出されたワイヤハーネス7に粘着テープ5を巻き付ける。また、第二の筒部とワイヤハーネス7とに粘着テープ(図示せず)を巻き付ける。勿論、反対方向、即ちワイヤハーネス7からグロメット1に向かって粘着テープ5を巻き付けていってもよい。以上のように、パネル6に取り付けられたグロメット1にワイヤハーネス7を固定する。   Then, the cover 33 is bent and the narrow portion 34 covers the center in the longitudinal direction of the slit 32. As shown in FIG. 3, the adhesive tape 5 is wound around the end portion of the wide portion 35 and the end portion of the cylindrical portion main body 31 from the base end to the distal end of the wide portion 35 to fix the cover portion 33 and the adhesive tape 5. Then, both ends of the slit 32 in the longitudinal direction are covered, and the adhesive tape 5 is continuously wound around the wire harness 7 led out from the cylindrical body 31. Further, an adhesive tape (not shown) is wound around the second tube portion and the wire harness 7.

Since the cover portion 33 is provided, the cover portion 33 covers the slit 32 to reliably prevent external noise such as the engine room E from entering the vehicle compartment R from the slit 32. In addition, it is possible to reliably prevent the wire harness 7 passed through the cylindrical body 31 from jumping out of the slit 32.

カバー部33がスリット32の内縁から立設した板状に設けられているので、カバー部33を折り曲げることによってスリット32を簡単かつ確実に覆うことができる。   Since the cover portion 33 is provided in a plate shape standing from the inner edge of the slit 32, the slit 32 can be covered easily and reliably by bending the cover portion 33.

カバー部33が、筒部本体31に連なりその幅が筒部本体31の長さより短く形成された幅狭部34と、該幅狭部34に連なりその幅が筒部本体31の長さと等しく形成された幅広部35とを備えているので、幅狭部34を簡単に折り曲げることができ、スリット32を簡単かつ確実にカバー部33で覆うことができる。   The cover portion 33 is connected to the cylindrical portion main body 31 and has a narrow width portion 34 whose width is shorter than the length of the cylindrical portion main body 31. The cover portion 33 is connected to the narrow width portion 34 and has a width equal to the length of the cylindrical portion main body 31. Since the wide portion 35 is provided, the narrow portion 34 can be easily bent, and the slit 32 can be easily and reliably covered with the cover portion 33.

本実施形態においては、保護部材としてグロメット1を例に挙げたが、保護部材はグロメット1に限定されるものではなく、例えばワイヤハーネス7に取り付けられる筒状のプロテクタであってもよい。   In this embodiment, although the grommet 1 was mentioned as an example as a protection member, a protection member is not limited to the grommet 1, For example, the cylindrical protector attached to the wire harness 7 may be sufficient.

また、本実施形態においては、幅狭部34がスリット32の長手方向中央の内縁に連なっていたが、幅狭部34を折り曲げにくくなるものの、幅狭部34がスリット32の内縁全長に連なって設けられていてもよい。   In the present embodiment, the narrow portion 34 is continuous with the inner edge at the center in the longitudinal direction of the slit 32. However, although the narrow portion 34 is difficult to bend, the narrow portion 34 is continuous with the entire inner edge of the slit 32. It may be provided.

また、本実施形態においては、グロメット1は全体としてT字状に形成されていたが、例えば筒部本体31とグロメット本体2とがL字状に配されてグロメット1がL字状に形成されていてもよく、筒部本体31がグロメット本体2と同軸に配されてグロメット1が直線状に形成されていてもよい。   Further, in the present embodiment, the grommet 1 is formed in a T shape as a whole. For example, the cylinder main body 31 and the grommet main body 2 are arranged in an L shape, and the grommet 1 is formed in an L shape. The cylinder part main body 31 may be coaxially arranged with the grommet main body 2, and the grommet 1 may be linearly formed.

また、本実施形態においては、筒部本体31及び第二の筒状部4の内径がワイヤハーネス7の外径より大きく設けられていたが、ワイヤハーネス7の内径より小さく設けられて、筒部本体31及び第二の筒状部4を弾性変形させて拡径させた状態でワイヤハーネス7を内側に通してもよい。   Moreover, in this embodiment, although the internal diameter of the cylinder part main body 31 and the 2nd cylindrical part 4 was provided larger than the outer diameter of the wire harness 7, it was provided smaller than the internal diameter of the wire harness 7, and a cylinder part is provided. The wire harness 7 may be passed through the inside in a state in which the main body 31 and the second cylindrical portion 4 are elastically deformed and expanded in diameter.

なお、前述した実施形態は本発明の代表的な形態を示したに過ぎず、本発明は、実施形態に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。   In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
