TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slide door device for an automobile, and more particularly, to a structure of a fully open stopper when the slide door is fully opened.
[0002]
[Prior art]
Generally, a slide door is configured to slide forward and backward by rolling a roller attached to the slide door along a guide rail provided on a vehicle body. At the rear end of the guide rail, a full-open stopper that regulates the rolling of the roller at a predetermined full-open position is set.
As a slide door device having such a fully-open stopper, for example, one described in Japanese Utility Model Laid-Open No. 2-38319 is known.
In this prior art, a slide door is swingably mounted with a bracket, two rollers for rolling the guide rail are provided on the front and rear of the bracket, and a full-open stopper is provided at the rear end of the guide rail. In the above, the buffer member is provided at a position where the front roller is disposed when the bracket collides with the fully-open stopper at the fully-open position of the slide door.
In this prior art, when the roller rolls on a portion of the guide rail that is displaced in the vehicle width direction, the bracket is configured to be swingable so as to absorb this relative displacement. When a collision occurs, the bracket oscillates and the roller presses the guide rail. At this time, a buffer member is provided to prevent the guide rail from being opened by the roller.
[0003]
[Problems to be solved by the invention]
In the above-described related art, when the bracket is fully opened, the bracket is caused to collide with the fully opened stopper. However, the roller may collide with the fully opened stopper in some cases. That is, in the roller provided at the lower part of the slide door that supports the weight of the slide door, since the acting force becomes large, the bracket often collides with the forward tilt stopper. In the roller provided in the intermediate portion, the configuration is often simplified by causing the roller to directly collide with the full-open stopper.
[0004]
However, in the technique in which the roller is caused to collide with the fully-open stopper in this way, when the slide door is swiftly opened, for example, the slide door is opened in a downward direction on a sloping road and the slide door is moved toward the fully open direction. When the slider slides vigorously, as shown in FIG. 4, the guide rail 01 may flex outwardly of the vehicle, or the guide rail 01 may open, and the roller 02 may fall off from the rear end of the guide rail 01. Was.
Among such problems, the problem that the rear end portion of the guide rail 01 bends easily occurs particularly in the upper guide rail that guides the slide at the upper part of the slide door. More specifically, a lower guide rail provided at a lower edge of an opening that is opened and closed by a slide door is configured such that a guide roller that supports weight and a guide roller that regulates a position in a vehicle width direction roll. Therefore, the shape of the guide rail is a shape having an opening on the outside of the vehicle. Therefore, when the lower guide rail is fixed to the vehicle body, spot welding is performed from the outside of the vehicle through the opening. However, the welding position and the position at which the roller rolls coincide with each other, and the roller attempts to move outside the vehicle. In this case, the input position with respect to the lower guide rail and the fixing point of the lower guide rail are substantially the same, and the lower guide rail is unlikely to bend outward.
On the other hand, since the upper guide rail provided on the upper edge of the opening is generally arranged with the opening as wide as possible, the roller 02 is inserted from below the guide rail 01 as shown in FIG. As a result, it is configured in a substantially rectangular shape as shown in the figure. Therefore, it is not possible to perform a fixing work such as spot welding on a portion where the roller 02 rolls on the guide rail 01 having such a shape from the outside of the vehicle. It is fixed by spot welding or the like at a position further away or above (the position indicated by * in the figure).
Therefore, as described above, when a force acts on the guide rail 01 from the roller 02 in the vehicle exterior direction as indicated by an arrow F, a moment acts on the fixed point * on the guide rail 01, and FIG. As shown in FIG. 7, the rear end portion was bent and the roller 02 was dropped.
[0005]
Although the opening of the guide rail 01 has been dealt with by the provision of the reinforcing material 03 as shown in FIG. 5, the rear end of the guide rail 01 is prevented from bending. In the past, there has been no effective countermeasure.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and the rear end of the guide rail is deformed when the slide door is regulated by the fully-open stopper. An object of the present invention is to prevent the number of points and the labor of the work from increasing, thereby preventing the roller from falling off the guide rail.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, in the slide door device of the present invention, a roller bracket provided on the inner surface of the slide door, on which a roller is pivotally mounted, and the roller is rollably supported, and the slide door slides. And a full-open stopper provided near the rear end of the guide rail and restricting slide of the slide door by collision of the roller or bracket at the fully open position of the slide door. In the device, the full-open stopper is formed of a rubber, a stopper portion having a stopper surface that collides with a roller or a bracket at a full-open position of the slide door, and includes a metal core fixed to a vehicle body, The core member is provided with an input support portion built in the stopper portion for receiving an input to the stopper surface, The stopper portion, notch is formed in the longitudinal direction from the side of the stop surface, the notch of the full open stopper, a rear end of the guide rail is inserted, the end face of the input supporting unit, the guide rail The vehicle is provided so as to overlap with the rear end portion and the vehicle outside in the vehicle width direction and with a part of the stopper portion interposed therebetween . Therefore, when the slide door is fully opened and the slide door attempts to move outside the vehicle and a large force acts on the guide rail from the roller to the outside of the vehicle, the force acting on the guide rail in the outside of the vehicle is is received in the core material of the fixed full open stopper, a rear end portion of the guide rail is prevented from flexing away from the vehicle body to the outside of the vehicle direction.
Also, by utilizing the core material of the existing fully-open stopper, the rear end of the guide rail can be prevented from being deformed outside the vehicle, and the roller can be prevented from falling off the guide rail. In addition, there is no increase in the labor of the mounting work.
[0008]
