Description of the Related Art Among the above-mentioned wire rods, for example, a wire harness arranged on a vehicle body is arranged in a narrow space around which other devices and members exist, and therefore penetrates a wall plate of the vehicle body. In many cases, the wire harness is bent in an L-shape later and wired in a posture parallel to the wall plate. When the wire harness arranged in such a manner makes contact with other peripheral devices and members, it causes an electrical obstacle due to vehicle body vibration. Therefore, it is necessary to accurately maintain the relative distance between the wire harness and the wall plate in that arrangement posture.

Moreover, the grommet itself changes into various shapes depending on the size of the wire harness, and the above-mentioned L-shaped bent arrangement of the wire harness arranged on the vehicle body also has extremely various changes in relative dimensions depending on the installation location. Since it has, the grommet for satisfying the various arrangement conditions has to have an extremely large number of product numbers, which complicates parts management due to the existence of multiple product numbers, and increases the cost due to dilutive mass production effects. Further, there is a possibility that a wrong shape may be attached to the wire harness due to a wrong shape due to selection error from those many product numbers. Furthermore, if the grommet with the fixing member is diverted without bending and wiring, the fixing member protruding in the shape of a tongue and in a free posture comes into contact with peripheral devices / members due to vehicle body vibration and causes abnormal noise during traveling. Become. The present invention provides a grommet that solves the above-mentioned drawbacks of the prior art.

い。In the grommet of the present invention having the above-described structure, the wire holding member having the index protrusions allows the wire rods to be inserted through the grommet and bent in an L-shape.
The relative size to the wall plate can be accurately regulated and held. The arrangement holding member is a separate body from the grommet body having a normal grommet function, and is, for example, a dimension regulation band suitable for various expected L-shaped bending arrangements in the arrangement of an automobile wire harness. By preparing one having a piece and combining it with the grommet main body as necessary, it is possible to cope with various bending arrangement conditions, and the number of parts of the grommet can be significantly reduced as compared with the above-mentioned conventional structure. Even if the grommet main body is used alone in a place that does not require the L-shaped bending arrangement, it normally functions as a grommet and there is no possibility of causing abnormal noise during traveling.
