is composed of a pair of front and rear upper and lower carriage rollers 27 that bear a lateral load, and a side roller 28 that is disposed between the carriage rollers 27 and bears a longitudinal load. Atsupa's roller 8 is composed of a pair of front and rear carriage rollers 29 that bear the lateral load. The lower roller 9 is composed of a pair of front and rear carriage rollers 30 that bear the lateral load, and a side roller 31 that is disposed between the carriage rollers 30 and bears the total load.

When the sliding door 6 is closed as shown in FIG. 1, a worker (not shown) may operate the outside handle 10 and the inside handle 11 attached to the front side of the waistline portion of the sliding door 6. After unlocking the front and rear locking mechanisms 12 and 13 that are linked to the operation of these handles 10 and 11, when the outside handle 10 and the inside handle 11 are moved backward to move the sliding door 6, the rollers 7, 8 and 9 are slidably engaged with the guide rails 3, 4, and 5, the slide door 6 moves backward from the door opening 2 to the outside of the vehicle body 1 at the rear, and the door opening 2 is opened. . In addition, when the slide door 6 is opened, the worker puts his hand on the outside handle 10 or the inside handle 11 and moves the slide door 6 forward, so that the rollers 7, 8, 9 are moved to the guide rail 3. . It is becoming more and more like this.

On the other hand, in the guide groove at the rear end of at least one of the guide rails 3, 4, and 5, for example, the lower guide rail 5, this 1
A stopper member 35 made of a soft cushioning material such as rubber or synthetic resin is provided to receive the roller bracket 23 corresponding to the roller 9 slidingly engaged with the two guide rails 5 at the fully open position of the sliding door 6. The roller bracket 23 received by the stopper member 35 and the roller bracket 23
A regulating means 36 for regulating forward rotation of the door arm 17 is provided on the corresponding door arm 17 .

FIG. 2 shows a roller bracket 23 to which a roller 9 consisting of the lower side roller 31 and a pair of front and rear carriage rollers 30 is rotatably attached.
The appearance is shown in which it is attached to the tip of the door arm 17 so as to be rotatable in the horizontal direction with a pivot 26. A receiving portion 38 for abutting against a stopper member 35 shown in FIG. 1 is formed at the rear end of the carriage roller mounting portion 37 of the roller bracket 23. As shown in FIG. Further, the regulating means 36 is formed by bending an extension portion 39 that projects from the tip of the door arm 17 forward beyond the roller bracket 23 so that it projects downward from the interior side edge of the vehicle interior beyond the roller bracket 23. It consists of a protrusion 40 and a receiving surface 42 corresponding to the protrusion 40 on the front end surface of the pivot attachment part 41 of the roller bracket 23.

According to this first embodiment, when the operator moves backward the sliding door 6 which is in the fully closed position shown by the solid line in FIG. In the process of moving from to just before the fully open position, when the protrusion 40 of the regulating means 36 is separated from the receiving surface 42, there is a slight clearance δ between the protrusion 40 and the receiving surface 42.
As a result, the roller bracket 23 performs a swinging motion, and this swinging motion of the roller bracket 23 allows the sliding door 6 to absorb the installation tolerance between the waist, top, and lower guide rails 3, 4, and 5. It opens smoothly. Due to the subsequent backward movement of the sliding door 6, the receiving portion 3 of the roller bracket 23 is moved to the fully open position shown by the dashed line in the figure.

The forward rotation of the door arm 17 is restricted, and the sliding door 6 is prevented from rattling in the front-rear direction.

FIG. 4 shows a roller 8 configured in a pair of carriage rollers 29 at the front and rear of Atsupa as a second embodiment.
Roller bracket 22 rotatably attached to
, which is attached to the tip of the door arm 16 with a pivot 25 so as to be rotatable in the horizontal direction. In FIG. 4, a receiving portion 38A is bent upward at the rear end of the carriage roller mounting portion 37A of the roller bracket 22. As shown in FIG. Further, a U-shaped rotation regulating member 45 is attached to the upper and lower ends of the pivot 25, straddling the door arm 16, and the rear edge of the web 46 of this rotation regulating member 45 abuts the door arm 16, and the web 43 A flange 48 whose front edge is bent at the front edge of the pivot attachment portion 47 of the roller bracket 22.
A restricting means 36A is configured to restrict forward rotation of the door arm 16 by coming into contact with the rear front end surface of the door arm 16.

In addition, in the present invention, the stopper member 35 and the regulating means 36, 36A are attached to the top and lower guide rails 4, 5, respectively, and to the waist, top, and lower guide rails 3, 4, 5, respectively. Furthermore, even if it is provided only on the top guide rail 4, the same effects as in the embodiment described above can be obtained.

Effects of the Invention As described above, according to the present invention, in a sliding door for a vehicle, a plurality of roller brackets that support rollers swing horizontally with respect to a door arm on the sliding door side when the sliding door is opened and closed. A stopper member is provided at a rear end portion of at least one of the plurality of guide rails to receive a roller bracket corresponding to a roller slidingly engaged with the one guide rail at a fully open position of the sliding door; The roller bracket received by the stopper member and the door arm corresponding to the roller bracket are provided with regulating means for regulating forward rotation of the door arm, so that when the sliding door is in the fully open position, the stopper member of the roller bracket When a contact reaction force acts on the door arm, the restricting means restricts the forward rotation of the door arm, thereby preventing the sliding door from rattling in the front-rear direction.

Moreover, according to the present invention, since the stopper member is brought into contact with the roller bracket, the impact upon contact is not directly transmitted to the roller. Therefore, uneven wear does not occur in the fitting portion between the roller and the shaft supporting the roller on the roller bracket, or in the roller itself, and the roller can rotate smoothly over a long period of time.
