  As shown in FIG. 9A, when the slide door 14 is opened by a predetermined opening or more and the roller unit 15 is in the straight portion 16 a of the center rail 16, the sorting pulley 38 is closer to the vehicle than the connector 52 of the slide door 14. The outer tubes 51 a and 51 b are curved between the pulley case 37 and the connector 52 on the indoor side.

  When the slide door 14 is closed from this state and the roller unit 15 reaches the retracting portion 16b of the center rail 16 as shown in FIG. 9B, the roller unit 15 is aligned with the direction of the retracting portion 16b. 14, the pulley case 37 rotates about the pulley shaft 39 around the pulley shaft 39 so as to follow the rotation of the roller unit 15. Then, when the pulley case 37 moves to a side-by-side position with respect to the connector 52 by the rotation of the roller unit 15, the pulley case 37 swings with respect to the mounting bracket 41 about the pulley shaft 39 and the pulley case 37 The outer tubes 51 a and 51 b are bent and straightened with the connector 52 (slide door 14), and the cables 32 a and 32 b are connected between the distribution pulley 38 and the slide door 14 regardless of the rotation of the roller unit 15. Thus, it is reliably guided by the outer tubes 51a and 51b.

  As described above, in the opening / closing device 31, the cables 32a and 32b are guided from the center rail 16 side to the slide door 14 side by the distribution pulley 38 provided in the roller unit 15, and the pulley case for accommodating the distribution pulley 38 is accommodated. 37 is swingably supported by a mounting bracket 41 fixed to the roller unit 15 by a pulley shaft 39, and the cables 32a and 32b are connected between the pulley case 37 and the slide door 14 with flexible outer tubes 51a, Since the guide is provided by 51b, the cables 32a and 32b can follow the rotation of the roller unit 15 with a simple routing structure. Thereby, the layout property of this switchgear 31 can be improved.

  It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention. For example, in the above-described embodiment, the outer tubes 51a and 51b have a three-layer structure. However, the outer tubes 51a and 51b are not limited to this, and may be formed to have flexibility such as resin or rubber. That's fine.

  In the above embodiment, each cable 32a, 32b is guided by one distribution pulley 38 having a closed pulley groove 38a and an open pulley groove 38b. Each of the cables 32a and 32b may be guided by two relatively rotating pulleys that are individually formed with pulley grooves 38a and 38b. In this case, when a tension mechanism is arranged on each connecting member 33, 34, the cable length between each distribution pulley and the connecting member 33, 34 changes slightly. It is particularly effective for the rotation corresponding to

  Further, in the above-described embodiment, the center drive system is such that the cables 32 a and 32 b are connected to the center rail 16. However, the present invention is not limited to this, and for example, the lower drive that connects the cables 32 a and 32 b to the lower rail 24. It is good also as a system.
