Such a sliding door is provided with a roller unit, and on the other hand, a guide rail is fixed to the side of the vehicle body, and the sliding door is moved along the side of the vehicle body by being movably mounted on the guide rail. It opens and closes in a sliding manner in the vehicle longitudinal direction. In addition, a pull-in portion that bends toward the inside of the vehicle body is provided on one end side of the guide rail. When the roller unit is guided by the pull-in portion, the slide door is drawn into the vehicle body and the side surface and the surface of the vehicle body It is designed to close together.

  In order to facilitate the opening / closing operation of such a sliding door, an automatic opening / closing device for a vehicle has been developed in which the sliding door is automatically opened / closed by the power of a drive unit. As the automatic opening / closing device, a cable type is known. In this case, the drive unit is disposed on the vehicle body, and the closed side cable and the open side cable drawn from the drive unit are respectively disposed at both ends of the guide rail. The roller unit is connected to the roller unit through an inversion pulley along the guide rail. Then, when one cable is wound up by the drive unit and the other cable is rewound, the slide door is pulled by the cable to open and close.

  In the cable type automatic opening and closing device, each cable is arranged along the guide rail inside the guide rail and is connected to the roller unit inside the guide rail, so it is arranged at both ends of the guide rail. The reversing pulleys are arranged in the longitudinal direction with respect to the guide rails. Therefore, in particular, the reversing pulley provided on the side of the retracting portion is arranged to protrude toward the vehicle interior side with respect to the end portion of the guide rail, and the vehicle interior space is narrowed to secure the space. It will be.

  Thus, for example, in the opening / closing device disclosed in Patent Document 1, each cable is disposed above or below the guide rail, and the reversing pulley is disposed above or below the guide rail so as to move toward the vehicle interior side of the guide pulley. I try to suppress the overhang.

On the other hand, a pair of cable connecting portions are arranged side by side in the direction along the guide rail at the position along the guide rail of the roller unit, that is, on the cable movement path in the guide rail. The cable is connected to the roller unit by locking the provided cylindrical cable end to the corresponding cable connecting portion. In the conventional automatic opening and closing device, the cable connecting portion is arranged at the central portion in the direction along the guide rail of the roller unit and at the position along the guide rail (on the moving path of the cable). The movement of the roller unit is earned by minimizing the interference between the cable connecting portion and the reversing pulley when moving to the stroke end of the rail.
