DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for attaching members to a bumper, and is suitable for attaching members such as a heat insulator panel and a reinforcing member to a bumper body.

[0002]

2. Description of the Related Art When a member such as a heat insulator panel or a reinforcing member is mounted on a bumper body, a female boss-shaped projection is provided on the bumper body side, and a screw is screwed into a hole of the projection to be mounted. ing. Also, at the point where the bumper is attached using a clip inserted into the engagement hole of the bracket provided on the vehicle body side, a clip attachment part is installed on the back side of the bumper wall so that the clip can not be seen from the outside. The bumper is mounted on the vehicle body by connecting the mounting portion to a bracket of the vehicle body with a clip.

[0003]

However, in the above-mentioned conventional mounting structure, if a projection is provided on a general surface of the vehicle body without irregularities or bends, so-called sink marks are easily generated on the surface of the bumper. For this purpose, a projection must be provided in a groove or a bent portion, so that there is a problem in that the degree of freedom of the provided position is low. Further, when the bumper is mounted on the vehicle body using the clip, the clip mounting portion is provided on the back side of the wall surface of the bumper, so that there is a problem that the mounting portion by the clip cannot be provided in the opening of the bumper.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to surely prevent so-called sink marks from being generated on the surface of a bumper.
An object of the present invention is to provide a member mounting structure for a vehicle body, which can improve the degree of freedom of the position of the protrusion and the appearance, and can provide a mounting portion such as a clip in an opening of a bumper.

[0005]

In order to achieve the above object, the present invention relates to a member mounting structure for a bumper for fixing a member to be mounted by engaging a connecting member with a projection provided on a bumper body. The bumper main body is provided with a mounting portion having a standing wall whose wall surface faces the member to be mounted, and the protrusion is provided so as to protrude from the wall surface of the standing wall. Further, the present invention provides a method of mounting a member to a bumper having an opening in a bumper body attached to a vehicle body via a bracket using a coupling member, wherein a panel is included in a member to be attached to the bumper body. In structure
The panel is arranged and coupled at a position corresponding to an opening of the bumper main body, and the coupling member and the bracket are covered and hidden by the panel.
