Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grommet, and particularly to a grommet suitable for holding penetrating members such as wiring and piping connecting an engine room and a passenger compartment in a vehicle body panel.

Conventional grommets include, for example, Fig. 1a,
There is something like the one shown in b. (Jitsukai 52-113400
In other words, this grommet 1 includes a cap-shaped mounting portion 4 whose base portion 4a is removably fitted into a through hole 3 drilled in a vehicle body panel 2, and a cap-shaped mounting portion 4 on the engine compartment E side of the mounting portion 4. It consists of a penetrating member integrally formed at the end, such as a cylindrical holding part 6 that tightly holds wiring, and the holding part 6 is oriented diagonally downward to prevent water from entering the room R side. , the holding portion 6 is attached to the base portion 4a of the through hole 3 and the cap-shaped attachment portion 4 that fits into the through hole 3.
The shape is not a perfect circle, for example, an oval shape, so that the direction is surely regulated. However, in the case of such a conventional grommet 1, the base 4a of the cap-shaped attachment part 4 and the vehicle body panel 2 to which it fits
Since the through-holes 3 have a shape other than a perfect circle, they may shift from each other depending on the method of work, resulting in a gap that causes water to enter the vehicle interior.

This idea was created by focusing on these conventional problems.In order to hold the penetrating member in close contact with the mounting member whose base is fitted into a perfectly circular through hole drilled in the vehicle body panel. By rotatably engaging the oblique base of the holding member, the holding member can be forced to always be oriented diagonally downward, thereby preventing water from penetrating into the interior of the room from the holding member. To provide a grommet which prevents water from entering a vehicle interior by eliminating a gap between a hole and a base of a mounting member.

This invention will be explained below based on the drawings.

Figures 2a and 2b are diagrams showing an embodiment of this invention.

Note that the same parts as in FIG. 1 will be described with the same reference numerals.

The grommet 11 of the present invention has a cap-shaped mounting member 1 inserted into a perfectly circular through hole 13 drilled in a vehicle body panel 2.
4 is fitted, and an annular groove 14b is formed on the inner circumferential surface of this mounting member 14, and an annular groove 14b is formed in the inner circumferential surface of the mounting member 14, and a penetrating member, for example, a diagonal cylindrical holding member 16 for tightly holding the wiring 5, is fitted into the base of the holding member 16. Annular flange 16a
is formed, and the annular flange 16a is rotatably engaged with the annular groove 14b. With this structure, the base 14a of the mounting member 14 of the grommet 11 can be casually fitted into the through hole 13 without any particular positional restriction. Even if the holding member 16 is not oriented obliquely downward when the holding member 16 is
can be forcibly rotated to direct it diagonally downward as desired. In this state, water can be prevented from entering from the holding member 16. In addition, the base 14 of the mounting member 14
Since the through hole 13 into which a is fitted is a perfect circle, the hole will not shift regardless of the method of work, that is, even if it is fitted in a careless manner, there will be no gap and water will not enter the passenger compartment. There is no such thing.

As explained above, according to this idea,
The base of the diagonal holding member that holds the penetrating member in close contact with the mounting member whose base is fitted into a perfectly circular through hole drilled in the vehicle body panel is structured to rotatably engage the mounting member. A gap is generated between the through hole and the base of the mounting member regardless of the method of work while reliably preventing water from entering the indoor side from the holding member by always forcing the member to face diagonally downward. This has the effect of reliably preventing water from entering the vehicle interior.
