DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external component mounting structure for mounting an external component, for example, a rear bumper, to a vehicle body.

[0002]

2. Description of the Related Art The mounting (fixing) of a rear bumper to the body of an automobile is generally performed by fastening with bolts and nuts or assembling using a clip-type rivet. By the way, the end of the bumper wraps around to the side of the vehicle body, and the wraparound terminal does not reach the rear wheel fender. In the case of a so-called vertical parting bumper, the stepping surface between the wraparound terminal and the vehicle body (a so-called throttle surface orthogonal to the side of the vehicle body) There is a demand that the parting-off part (joining part) be fitted exactly so that no gap is formed between the parting part. In order to respond to this demand, a configuration has conventionally been adopted in which a mating surface between a mounting flange provided on a wraparound terminal and a step surface of a vehicle body is directly fastened with bolts and nuts.

[0003]

By the way, due to the process and structure of the press die at the time of molding the vehicle body, depending on the location, it may not be possible to set the mounting hole of the bumper on the step surface of the vehicle body. In such a form in which the butting surfaces are directly fixed, it is impossible to fix the vicinity of the vertical part to the vehicle body. As a result, there arises a problem that the appearance is deteriorated due to the opening of the vertical parting portion or that the bumper is pressed when the bumper is pressed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to attach an exterior component to a vehicle body when the exterior component is attached to the vehicle body. It is an object of the present invention to provide an exterior component mounting structure that can be mounted even when a mounting portion cannot be formed at a location where the mounting is performed.

Means for Solving the Problems In order to achieve the above object, an exterior component mounting structure according to the present invention has a structure as described in each claim. The mounting structure for an exterior component according to claim 1, wherein the exterior component is attached to a vehicle body of a vehicle via a fixing tool, and the fixing tool includes a first fastening portion attachable to the vehicle body; It has a second fastening portion attachable to an article, and is provided at a different position from the first fastening portion and the second fastening portion. That is,
It is possible to indirectly fix the exterior component to the vehicle body via the fixing tool. For this reason, when attaching the exterior component to the vehicle body, the exterior component can be attached even when the relative position between the attachment portion formed on the exterior component and the attachment portion formed on the vehicle body side is different. In other words, when it is not possible to form a mounting portion on the vehicle body at a location corresponding to the mounting portion of the exterior component, the exterior component can be mounted on the vehicle body by providing the mounting portion at a different position that does not correspond. It becomes possible.

In the exterior component mounting structure according to the second aspect, the first fastening portion and the second fastening portion of the fixture are formed on different surfaces that intersect each other. Accordingly, when the mounting portion on the vehicle body side and the mounting portion of the exterior product intersect, the exterior product can be mounted on the vehicle body. For example,
In the case where a bumper with a vertical cutoff to the vehicle body is attached to the vehicle body, by attaching the first fastening portion to a surface intersecting with the step surface of the vehicle body in a crossing manner, and attaching the second fastening portion to a terminal around the bumper The vertical parting part can be attached with good appearance.

[0007] As described in claim 3, it is preferable that the fixture in the exterior component mounting structure according to claim 1 or 2 is a retainer made of resin. By using resin, a fixture that is inexpensive and easy to manufacture can be provided.

In the exterior component mounting structure according to the fourth aspect, the second fastening portion of the fixture has an arm that can be elastically deformed,
The arm is configured to press the exterior component toward the vehicle body with a pressing force due to a rebound. According to such a configuration, it is possible to absorb a variation in dimensions related to a mounting portion of the exterior component or a variation in an assembling position between the fixture and the vehicle body. In this case, when the direction of the bending axis of the arm is set to be parallel to the mounting direction of the exterior component, it is possible to reduce the size of the arm in the mounting direction and achieve downsizing.

According to a fifth aspect of the present invention, there is provided an exterior component mounting structure for mounting the external component on a vehicle body of an automobile using a fixing device, wherein the fixing device includes a first fastening portion attachable to the vehicle body. And a second fastening portion having an elastically deformable arm, and the exterior is pressed toward the vehicle body by elastic deformation of the arm. When such a configuration is employed, the gap between the two members can be eliminated by pressing the exterior component toward the vehicle body with the elastic force of the elastically deformable arm.
