Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a mounting structure for a garnish that decorates a vehicle body.

<Prior Art> Various garnishes are attached to the body of an automobile for decorative purposes.

The conventional garnish mounting structure has figures 5 and 6.
I found something like the one shown in the picture. In the case shown in FIG. 5, a bolt 51 is installed in a garnish 50 in advance, and the bolt 5 is passed through a mounting hole in a vehicle body 52.
The garnish 50 is attached to the vehicle body 52 by screwing a nut 53 onto the garnish 50. Further, in the case shown in FIG. 6, a clip 61 is attached to the garnish 60 in advance, and the clip 61 is pushed through a mounting hole 62a provided in the vehicle body 62, and the clip 61 is engaged with the vehicle body 62 on the opposite side. As a result, the garnish 60 is attached to the vehicle body 62.

<Problems to be solved by the invention> In the conventional garnish mounting structure shown in FIG. 5, the bolts 51 protrude inward of the vehicle body. In this case, the bolt 51 protrudes into the trunk room, causing trouble in loading and unloading luggage. It is also possible to make the bolt 51 as short as the height of the nut 53, but
In this case, the screwing operation between the bolt 51 and the nut 53 becomes extremely difficult.

In addition, in the conventional garnish mounting structure shown in FIG.
1, there was a problem that sufficient mounting rigidity of the garnish 60 could not be obtained. It is conceivable to make the clip 61 highly rigid, but this would make the attachment work difficult and, for some reason, the workability of removing the garnish 60 would be extremely poor.

In addition, in the conventional garnish mounting structure, the garnish is fixed to the vehicle body without any degree of freedom, so if the resin garnish is thermally expanded or contracted, cracks may occur in the mounting part. There was also the problem of putting it away.

The present invention has been devised in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a garnish mounting structure that reasonably solves the conventional problems.

<Means for Solving the Problems> The garnish mounting structure of the present invention has a flange portion and a threaded portion, and a large diameter hole is formed in the flange portion, and a large diameter hole is formed in the threaded portion. A grommet in which a continuous small-diameter hole is formed is slidably engaged with the garnish at the flange portion, and the garnish is attached to the vehicle body by a screw that passes through the large-diameter hole and is screwed into the small-diameter hole. It is characterized by

<Function> The garnish is attached to the vehicle body with the head of the screw located inside the vehicle body, and the garnish is slidable relative to the grommet, allowing thermal expansion and contraction of the garnish.

<Example> An example of the present invention will be described based on the drawings.
FIG. 1 is a perspective view showing the rear part of the vehicle according to the present embodiment, FIG. 2 is a sectional view taken along the - arrow in FIG.
The figure is a sectional view taken along the - arrow in FIG. 2, and FIG. 4 is an exploded perspective view of the garnish mounting portion.

A resin garnish 1 that covers a trunk room at the rear of the vehicle is attached to a vehicle body 30 using resin grommets 10 and tapping screws 20.

The garnish 1 is provided with a plurality of attachment parts 2, each of which has a groove 3 extending in the longitudinal direction of the garnish 1 (in the vehicle width direction in this embodiment).
is formed.

The grommet 10 has a pair of flanges 11 on its outer surface.
a, 11b and has a relatively large diameter hole 12 formed therein, and a relatively small diameter hole 10a that is integrally molded with the flange part 10a and continues coaxially with the large diameter hole 12 inside. It consists of a threaded part 10b in which a small diameter hole 13 is formed. This grommet 10 has a groove 3 in its flange portion 10a.
Although the grommet 10 is attached to the attachment part 2 by being fitted into the groove 3, the grommet 10 can be slid along the groove 3 to some extent. The flange portion 10a has a rectangular shape so as not to rotate within the groove 3, and a protrusion 2a is provided at the entrance of the groove 3 of the mounting portion 2 so that the grommet 10 fitted into the groove 3 It is designed to prevent it from falling off easily.

The tapping screw 20 has a smaller diameter than the large diameter hole 12 and a larger diameter than the small diameter hole 13, and is inserted into a mounting hole 31 provided in the vehicle body 30 from the inside to the outside of the vehicle body 30. The tapping screw 20 passes through the large diameter hole 12 of the flange portion 10a and is screwed into the small diameter hole 13 of the threaded portion 10b.
The screw thread is cut by the screwing together.

As described above, by attaching the grommet 10 attached to the mounting portion 2 to the vehicle body 30 using the tapping screws 20, the garnish 1 is attached to the vehicle body 30.
installed on.

The installation work of the above-mentioned garnish 1 will be explained. First, the grommet 10 is attached to the attachment part 2. At this time, the grommet 10 is able to slide by several millimeters relative to the mounting portion 2, and even if thermal expansion or contraction occurs in the garnish 1 attached to the vehicle body 30, this can be tolerated. There is.
Incidentally, since the tapping screw 20 passes through the large diameter hole 12 and is not screwed into the flange portion 10a, the ability of the grommet 10 to slide on the mounting portion 2 is not inhibited even by tightening the tapping screw 20. Next, the garnish 1 is attached to the vehicle body 30 by screwing the tapping screw 20 into the grommet 10. At this time, the grommet 10 is prevented from falling off from the mounting portion 2 and is also prevented from rotating with the tapping screw 20, so that the work can be easily performed. Further, since the head 20a of the tapping screw 20 is located inside the vehicle body 30, it will not get caught in luggage etc. that are taken in and out of the trunk room.

In the above embodiment, the tapping screw 20 is used to cut and screw into the grommet 10, but of course a screw may be screwed into a grommet in which a screw hole is formed. Also,
Although the mounting portion 2 is sandwiched between the pair of flanges 11a and 11b, only one flange may be used as long as a groove for sandwiching the flange is provided on the side surface of the groove 3 of the mounting portion 2.

<Effects of the Invention> According to the garnish mounting structure of the present invention, the garnish can be firmly mounted to the vehicle body with screws without forming protrusions on the inside of the vehicle body. Further, thermal expansion and contraction of the garnish can be tolerated, and cracking of the mounting portion of the garnish can be prevented.
