Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fully open stopper structure for a sliding door of an automobile, and more particularly to a fully open stopper structure when the slide door is fully opened.
[0002]
[Prior art]
Generally, the slide door is configured to slide back and forth by rolling a roller attached to the slide door along a guide rail provided on the vehicle body. A fully open stopper is provided at the rear end of the guide rail to restrict roller rolling at a predetermined fully open position.
[0003]
As a slide door fully open stopper structure having such a fully open stopper, a structure as shown in FIG. 6 is known. In this prior art, a guide roller bracket 04 is swingably attached to a slide door, and a guide roller 041 for rolling the guide rail 03 is provided on the guide roller bracket 04. In the guide rail 03, the fully open position of the slide door is provided. Thus, the guide roller bracket 04 or the guide roller 041 hits the elastic member 022 that covers the metal core 021 provided on the stopper 02 and restricts sliding of the sliding door at the fully open position.
[0004]
In this prior art, when the guide roller bracket 04 or the guide roller 041 hits the elastic member 022, the reaction of the guide roller 041 causes the guide roller 041 to be located on the outer side in the vehicle width direction of the rear end side surface of the guide rail 03 having a substantially U-shaped cross section. In order to prevent the side surface of the guide rail 03 from deforming outward when it hits the inner surface, and thus the entire rear end portion of the guide rail 03 from deforming outward, a reinforcement separate from the guide rail 03 is provided at the rear end of the guide rail 03. The member 031 was reinforced by spot welding.
[0005]
Further, as shown in FIG. 8, the guide rail 03 is provided with a plurality of welded weld bolts 033 welded, and the weld bolts 033 are provided on the vehicle body 01 side as shown in FIG. The guide rail 03 was attached to the vehicle body 01 by being inserted into a mounting hole not shown.
[0006]
Further, it is necessary to provide means for holding the rear end portion of the guide rail 03 so that the guide rail 03 does not fall off even if the weld bolt 033 is peeled off. It was fastened to the car body from the outside of 03. That is, when the bolt 05 is fastened from the outside of the vehicle, it cannot be fastened to the U-shaped portion. Therefore, conventionally, as shown in FIG. 7, a flange portion 034 is provided below the U-shaped portion, an insertion hole 032 is provided in the flange portion 034, and the bolt 05 is fastened.
[0007]
[Problems to be solved by the invention]
However, in the above-described prior art, since the reinforcing member 031 is attached to the guide rail 03 by spot welding, the spot of the spot welding is attached to the guide rail, and when the slide door is opened, There was a problem that the spot welding dent was seen and the appearance was deteriorated.
In addition, since the reinforcing member 031 is attached to the guide rail 03 as a separate member, there is a problem that the number of parts increases, and the cost and weight increase.
Further, since the flange portion 034 is provided and fixed with the bolt 05 to prevent the rear end portion of the guide rail 03 from coming off, there is a problem that the weight is increased, and the guide roller 041 is fully opened when the guide rail 03 is fully opened. When a force is applied to the guide rail 03 in the vehicle outward direction, the input point from the guide roller 041 and the support point by the bolt 05 are arranged at different positions in the vertical direction. In order to prevent this, it is necessary to take measures such as increasing the size of the reinforcing member 031 described above.
Further, since the rear end portion of the guide rail 03 is fixed to the vehicle body with the bolt 05, it is necessary to provide the flange portion 034. Therefore, there is a problem that the weight of the guide rail 03 becomes heavy.
[0008]
The present invention has been made paying attention to the above-described conventional problems, and aims to improve the appearance of the guide rail and reduce the cost and weight of parts.
