Description

  The present invention relates to a bumper positioning structure for positioning an end portion of a bumper with respect to an end portion of a side garnish attached to a side outer panel of a vehicle body.

Some vehicles improve the overall appearance by attaching side garnishes, which are external parts, to the left and right side outer panels. In this case, the left and right ends of the bumper extend to the end of the side garnish and are attached to the vehicle body. Since the side garnish and the bumper are separately attached to the vehicle body, the end of the bumper with respect to the end of the side garnish is easily displaced. In order to improve the appearance of the vehicle, it is required that the ends are positioned with high accuracy. For this reason, the development of a technique that enhances the appearance by positioning the end portions with high accuracy is being promoted (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 11-342813

  Hereinafter, an outline of the bumper positioning structure disclosed in Patent Document 1 will be described with reference to FIG. FIG. 10 is a schematic diagram of a bumper positioning structure in a conventional vehicle. FIG. 10A shows a vehicle including a side garnish and a bumper. FIG.10 (b) shows the decomposition | disassembly state of a side garnish and a bumper. FIG.10 (c) shows the cross section along the cc line of Fig.10 (a).

As shown in FIG. 10, the conventional vehicle 100 has a side garnish 103 attached to the lower portion of the side outer panel 102 at the rear portion of the vehicle body 101, and a rear bumper 104 having a substantially U-shape in plan view attached to the rear end portion of the vehicle body 101. Is.
The side garnish 103 is elongated in the front-rear direction of the vehicle body 101 and has a vertical wall-shaped positioning wall 105 at the rear end. The positioning wall portion 105 has a plurality of positioning holes 106. On the other hand, the end 107 of the rear bumper 104 has a stopper piece 108 that faces the positioning wall 105. The stopper piece 108 has a cusp 109 at the tip. The point 109 is inserted into the positioning hole 106.

In the bumper positioning structure having such a configuration, the side garnish 103 and the rear bumper 104 are assembled in the following procedure.
First, the side garnish 103 is attached to the side outer panel 102.
Next, the stopper piece 108 is applied to the positioning wall portion 105 while inserting the sharpened portion 109 into the positioning hole 106. As a result, the rear bumper 104 is positioned with respect to the side garnish 103.
Next, the positioning state of the rear bumper 104 with respect to the side garnish 103 is temporarily held. If not temporarily held, the rear bumper 104 falls out of the side garnish 103.
Finally, the temporarily held rear bumper 104 is attached to the vehicle body 101.

  However, in the bumper positioning structure disclosed in Patent Document 1, it is necessary to temporarily hold the positioning state of the rear bumper 104 with respect to the side garnish 103 until the rear bumper 104 is attached to the vehicle body 101. For this reason, the assembling work is troublesome and becomes a factor of increasing the number of assembling steps.

On the other hand, it is conceivable to provide a latching claw for latching in the positioning hole 106 at the apex 109. When the apex 109 is inserted into the positioning hole 106, it can be temporarily stopped by hooking the hooking pawl on the positioning hole 106.
However, the temporary holding state is unstable simply by hooking the pawl on the positioning hole 106. Temporary holding cannot be performed in a state where the positioning accuracy of the rear bumper 104 with respect to the side garnish 103 is maintained. For this reason, it is necessary to temporarily hold the positioning state of the rear bumper 104 by another means. After all, it becomes a factor to increase the assembly man-hours.

  It is an object of the present invention to provide a technique capable of easily and reliably holding a bumper on a side garnish while maintaining the positioning accuracy of the bumper with respect to the side garnish.

The latching state of the latching claw and the latching hole is reliably maintained. Therefore, the flange fitted in the alignment recess is surely prevented from coming off.

  Thus, according to the invention which concerns on Claim 1, a bumper can be easily and reliably hold | maintained to a side garnish in the state which maintained the positioning accuracy of the bumper with respect to a side garnish. In addition, the man-hours for positioning the bumper on the side garnish can be reduced.

  According to the invention which concerns on Claim 2, the magnitude | size of the space | interval of an alignment recessed part is set so that the edge part of a bumper may be positioned in the contact / separation direction with respect to the opposing surface of a side garnish. For this reason, the flange fitted in the alignment recess is positioned with higher accuracy. The end of the bumper can be positioned more accurately in the contact / separation direction with respect to the facing surface.

  Moreover, when the outer surface of the bumper matches the outer surface of the side garnish, the tip of the bumper diameter positioning convex portion in the spacer is configured to contact the inner peripheral surface of the bumper. Moreover, when the outer surface of the bumper matches the outer surface of the side garnish, the latching claw is configured to be latched in the latching hole. For this reason, the outer surface of the bumper can be positioned more accurately with respect to the outer surface of the side garnish.

  Thus, according to the invention according to claim 2, the bumper can be easily and reliably attached to the side garnish in a state in which the positioning accuracy of the bumper with respect to the side garnish is improved in all the front and rear, top and bottom, and left and right directions of the vehicle body.
