[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a grommet, and more specifically, when inserting a wire harness into a mounting hole of a vehicle body panel, the mounting hole and the wire harness are prevented from coming into contact with each other, and water and the like enter the panel through the mounting hole. A grommet that can be prevented.
[0002]
[Prior art]
Generally, when a grommet holding a wire harness is inserted into a mounting hole formed in a panel member that separates the outside and the inside of a vehicle body, the mounting hole and the grommet are prevented from coming into contact with each other, and water or the like is removed from the mounting hole. Grommets are used to prevent intrusion into the panel (room) from the gap between the corrugated pipes.
[0003]
FIG. 6 shows a conventional grommet of this kind.
[0004]
In FIG. 6, reference numeral 1 denotes a grommet made of rubber or the like. This grommet 1 has a cylindrical large-diameter portion 2 having an annular groove 2a formed in an outer peripheral portion to be fitted into a mounting hole 4a of a vehicle body panel 4. And a small cylindrical portion 3 protruding from the large cylindrical portion 2 and through which a wire harness 5 can be inserted.
[0005]
In the grommet 1 having such a configuration, the cylindrical large diameter portion 2 is inserted through the insertion hole 4a from the left side (outside the vehicle) to the right side (in-house) in FIG. By fitting the annular groove 2a into the vehicle body panel 4, the mounting hole 4a is closed.
[0006]
[Problems to be solved by the invention]
However, in the case of such a grommet 1, as shown in FIG. 7, when there is an obstacle (engine, transmission, etc.) 6 in the vehicle interior near the mounting portion of the grommet 1, the obstacle 6 is avoided. After bending the wire harness 5, the wire harness 5 is held by the binding band 7 and attached to the vehicle body panel 4.
[0007]
For this reason, since the bending work of the wire harness 5 must be performed at a short distance H between the vehicle body panel 4 and the obstacle 6, there is a problem that the workability of the wiring work of the wire harness 5 is deteriorated.
[0008]
Further, the bending angle of the wire harness 5 with respect to the distance H between the vehicle body panel 4 and the obstacle 6 changes depending on the mounting tolerance when the binding band 7 is mounted on the vehicle body panel 4. The problem that it interferes with has arisen.
[0009]
Accordingly, the present invention provides a grommet that can reliably prevent interference with an obstacle, easily bend and wire a wire bundle, and improve the workability of wiring work of the wire bundle. It is an object.
[0010]

It is characterized by comprising from an engaging member engaged with the main assembly guide
[0015]
In this case, by fixing the wire bundle to the guide member with a tape or the like, the wire bundle can be bent in advance and attached to the grommet. Therefore, even when the distance between the panel member and the obstacle is short, the wire rod can be used. The bundle of wires can be easily bent and wired by reliably preventing the bundle from interfering with obstacles. As a result, the workability of the wiring work of the wire bundle can be improved.
Also, after the wire bundle is attached to the main body guide, the cover member is matched to the main body guide via the hinge, and the cover member is engaged with the main body guide by the engaging means, so that the wire bundle can be used without using a tape or the like. It can be fixed to the guide member.
