According to the above-mentioned means, when installing the bumper 1,
The positioning jig 5 is attached to the bumper 1, and the positioning part 6 (locating pin) of this jig 5 is attached to the vehicle body 2.
By engaging the clip 8 for attaching the vehicle body seal member 7 to the vehicle body seal member 7 (radiator support panel 3), the bumper 1 can be properly positioned relative to the vehicle body 2 (radiator support panel 3), and this positioning also allows the bumper 1 is fixed to the vehicle body 2 (side member 4) via the bumper arm 9, and then the positioning jig 5 is removed from the bumper 1. After the bumper 1 is positioned and installed (that is, after the vehicle assembly is completed), the positioning jig 5 is removed from the bumper 1. No members remain as part of the vehicle body components, and an increase in the number of parts can be prevented.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The drawings from FIG. 1 to FIG. 4 show an embodiment of this invention.To explain the mounting structure of a front bumper attached to the front of a vehicle body as an example, as shown in FIG. (hereinafter simply referred to as bumper 1) and the upper radiator grille G
In order to improve the appearance and quality by maintaining a constant gap between After positioning the bumper 1 at an appropriate position, the bumper 1 is attached to a vehicle body 2 such as a side frame via a bumper arm 9.
(hereinafter simply referred to as side frame 4).

In the bumper mounting structure constructed in this manner, as shown in FIGS. 1 to 3, a removable positioning jig 5 is attached to the bumper 1 in order to position the bumper 1 at an appropriate position. In addition, this jig 5 has a positioning part 6 (hereinafter referred to as
(simply referred to as a locate pin 6) is provided.

Additionally, a new locate pin 6 is installed on the side of the radiator support panel 3 that engages with the locate pin 6 of this jig 5 in order to position the bumper 1.
A clip 8 for fixing the vehicle body sealing member 7 made of a rubber material or the like is fixed to the radiator support panel 3 in order to seal the inside and outside of the engine compartment, rather than forming an engagement part (hole, dedicated grommet, etc.). , engage the locate pin 6 of the jig 5 with this clip 8 to position the bumper 1 at an appropriate position, and after positioning or after positioning and fixing the bumper 1,
The jig 5 is removed.

The existing car body seal member 7 with which the locate pin 6 of the jig 5 engages has a fixing clip 8 made of a resin material or the like, and when the locate pin 6 engages with the existing vehicle body seal member 7, it directly attaches to the radiator support panel 3.
It also serves to prevent the radiator support panel 3 from coming into contact with or engaging with it, thereby preventing the radiator support panel 3 from being damaged and rusting.

Then, position the bumper 1 at an appropriate position,
When attaching the bumper 1 to the side frame 4 via the bumper arm 9, first attach the jig 5 for positioning the bumper 1 to the bumper 1 via the pins 51, etc., as shown in FIGS. After mounting and setting, the locate pin 6 provided on the jig 5 is
By engaging the clip 8 for fixing the vehicle body seal member 7 to the radiator support panel 3 (see FIG. 2), the bumper 1 is positioned at an appropriate position relative to the radiator support panel 3.

Then, the bumper 1 properly positioned in this way is attached to the side frame 4 via the bumper arm 9.
The installation of the bumper 1 can be completed by fixing it to the bumper 1 and removing the positioning jig 5, which has been installed and set on the bumper 1, from the bumper 1 after positioning and fixing (see Fig. 1). be.

In this embodiment, after the bumper 1 is fixed and attached to the side frame 4 via the bumper arm 9, the jig 5 is removed.
If the configuration is such that the bumper 1 that has been positioned at the proper position can be held in that state (proper position state) by temporary attachment or the like, the jig 5 may be removed immediately after the bumper 1 is positioned before being fixed. It is something.

Also, bumper 1 using this positioning method
Adjustment to the appropriate position, that is, absorption of assembly errors between the bumper 1 and the bumper arm 9 or coupling errors between the side frame 4 and the radiator support panel 3 in order to fix the bumper arm 9, is done by adjusting the alignment between the bumper arm 9 and the side frame 4 The fixing portion is configured to have a long hole shape, for example.

Therefore, by engaging the positioning jig 5 and the locating pin 6 of the jig 5 with the clip 8 on the radiator support panel 3 side, the bumper 1 can be positioned and attached to the radiator support panel 3 at an appropriate position. Therefore, the gap between the bumper 1 and the radiator grille G above it can always be kept constant, and the appearance and quality can be greatly improved.

Further, the positioning jig 5 is configured to be detachable from the bumper 1, and can be removed from the bumper 1 after the bumper 1 is positioned at a proper position or after the bumper is positioned and fixed. Since no members for positioning remain as part of the vehicle components (that is, after the vehicle assembly is completed), an increase in the number of parts for positioning the bumper 1 can be prevented.

Further, on the side of the radiator support panel 3 that the locating pin 6 of the jig 5 engages with in order to position the bumper 1, the clip 9 for fixing the vehicle body seal member 8 to the radiator support panel 3 can be used. There is no need to newly form engagement members such as holes and dedicated grommets on the support panel 3 side, and the number of parts can thereby be reduced.

Furthermore, since the clip 9 made of a resin material or the like is used for fixing the vehicle body seal member 8, when the locate pin 6 of the jig 5 is engaged, the locate pin 6 is attached to the radiator support panel 3. This radiator support panel 3 can prevent contact or direct engagement.
This can prevent damage and rust in the vicinity of the engagement part.

Although the above embodiments have been described with respect to a front bumper that is attached to the front of the vehicle body, the present invention can also be applied to the mounting structure of a rear bumper that is attached to the rear of the vehicle body. It can also be applied to a so-called shock absorbing bumper, in which case Figs.
The bumper 1 shown in the figure will be replaced with a bumper reinforcement.

[Effect of idea]

As mentioned above, this idea provides a removable positioning jig for the bumper, and engages the positioning part of this jig with the car body seal member fixing clip on the car body to position and install the bumper. After the bumper has been positioned or has been positioned and fixed, the jig can be removed so that the positioning member can be removed as a part of the vehicle body component after the bumper is installed (i.e. after vehicle assembly is completed). This makes it possible to prevent an increase in the number of parts, and the use of this positioning jig and the engagement of the positioning part of this jig with the vehicle body to ensure that the bumper is always in the correct position. Since the bumper can be positioned and installed, the gap between the installed bumper and the outfitting parts above it can always be kept constant, and the appearance and quality can be greatly improved.
