Description

The present invention relates to a sliding door device for a vehicle.

In general, a sliding door device for a vehicle includes a plurality of guide rails extending in the vehicle front-rear direction and a plurality of guide roller units connected to each of these guide rails so as to be relatively movable along the extending direction. I have. Then, by supporting the slide door to the vehicle body via each of these guide rails and guide roller units, the slide door is formed on the side surface of the vehicle body based on the front-rear movement of the slide door along the extending direction of each guide rail. It is possible to open and close the door opening of the vehicle.

For example, the sliding door device described in Patent Document 1 includes lower rails having first and second guide roller engaging portions (rails) arranged in the vehicle width direction and arranged at the lower edge of the door opening. There is. Further, the lower guide roller unit connected to the lower rail includes a support arm rotatably connected to the slide door, and first and second rotatably connected to the support arm. A roller support portion and a roller support portion are provided. Further, the first roller support portion is provided with a first guide roller that engages with the first guide roller engaging portion, and the second roller support portion is provided with a second guide roller engaging portion. A second guide roller is provided to engage. Then, in the lower rail, the second guide roller engaging portion arranged inside in the vehicle width direction is separated from the first guide roller engaging portion at the longitudinal end portion in the direction in which the slide door closes. The structure is curved inward in the vehicle width direction.

That is, by adopting such a configuration, the support arm connected to the slide door can be rotated more greatly at the longitudinal end of the lower rail which is the closing operation position of the slide door. As a result, the relative positions of the first and second roller support portions guided by the first and second guide roller engaging portions are changed, so that the accommodation space of the guide roller unit can be suppressed to a small size. it can.

Further, in many cases, when connecting the guide roller unit to the guide rail, the guide roller is inside the guide roller engaging portion through a notch provided in the side wall portion located on the outer side in the vehicle width direction. Is thrown in. Then, after that, the configuration of closing this notch has become common.

Japanese Unexamined Patent Publication No. 2008-285964

However, in the configuration in which the notch for insertion is provided in the side wall portion of the guide roller engaging portion as described above, the work of closing the notch after the guide roller is inserted is complicated. The above-mentioned Patent Document 1 describes that the first and second guide roller engaging portions are arranged at substantially the same height, but the vehicle width is relative to each of these guide roller engaging portions. When each guide roller is to be loaded from the outside in the direction, the guide roller engaging portion on the outside in the vehicle width direction hinders the loading of the guide roller to the guide roller engaging portion on the inside in the vehicle width direction. Further, in order to avoid the occurrence of such a problem, it is conceivable to insert the guide roller into the guide roller engaging portion from the longitudinal end portion thereof. However, the loading operation of the guide roller via the longitudinal end is required to finely adjust the position of the guide roller with respect to the longitudinal end of the guide roller engaging portion that opens in the extending direction. It is not always possible to visually confirm the confirmation. Further, since the support member of the guide roller rotates with respect to the slide door, there is a problem that it becomes more difficult to connect the guide roller unit to the guide rail. Therefore, in this respect, further improvement is made. It left room for it.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a sliding door device for a vehicle capable of more easily connecting a guide roller unit to a guide rail. It is in.

A vehicle sliding door device for solving the above problems has a guide rail extending in the front-rear direction of the vehicle along the peripheral edge of a door opening formed on the side surface of the vehicle body, and a guide rail connected to the guide rail on the side surface of the vehicle body. The guide roller unit includes a guide roller unit that supports the slide door, and the guide roller unit includes a rotation arm that is rotatably connected to the slide door and a guide roller that is supported by the rotation arm. The guide rail has a guide roller engaging portion that guides the guide roller unit in the extending direction of the guide rail by engaging with the guide roller, and the guide rail has the guide rail. A vehicle slide having a guide wall connected to the longitudinal end of the guide roller engaging portion opened in the extending direction and provided with a guide portion for guiding the guide roller inside the guide roller engaging portion. In the door device, the guide roller engaging portion is arranged inside the first guide roller engaging portion extending in the vehicle front-rear direction and the first guide roller engaging portion in the vehicle width direction, and is arranged in the vehicle front-rear direction.
