Ru.

  The storage portion 6 is provided inside the drive belt 3, that is, inside the annular drive belt 3 and in proximity to the sprocket 23. Further, the storage portion 6 is provided to extend in the moving direction of the opposing drive belt 3. The storage section 6 holds the bottom plate 61, a guide member 62 vertically erected upward from the bottom plate 61, and the wire harness 4 vertically erected upward from the bottom plate 61 while being pulled into the accommodation section 6. And a side wall 64 provided opposite to the holding member 63.

  The bottom plate 61 is a substantially rectangular plate-like member, and is extended in the moving direction of the drive belt 3. The guide member 62 is provided in parallel with the moving direction on the slide door side of the drive belt 3, and among the long sides of the bottom plate 61, the side on the center side of the vehicle 2 (the side opposite to the slide door side) Stands along the The guide member 62 regulates the bending of the wire harness 4 so that the wire harness 4 stored in the storage portion 6 does not protrude in the central side direction of the vehicle 2. When the wire harness 4 is stored, the guide member 62 can restrict the bending of the wire harness 4 between the portion fixed to the vehicle 2 and the curved portion.

  The holding member 63 is erected along the side far from the sprocket 23 among the short sides of the rectangle of the bottom plate 61. The holding member 63 is formed shorter than the length of the short side of the bottom plate 61, and a gap is provided between the holding member 63 and the guide member 62. The clearance holds the wire harness 4 and forms a fixing port 65 for fixing the wire harness 4 closer to the vehicle 2.

  The wire harness 4 in which one connector is connected to the battery of the vehicle 2 is drawn into the storage portion 6 from the fixing port 65. In the state where the slide door in FIG. 1 is closed, the wire harness 4 draws a circular arc of approximately 180 degrees in the storage portion 6, curves and folds back, and is pulled out from the storage portion 6.

  The wire harness 4 pulled out from the storage portion 6 is disposed parallel to the moving direction of the drive belt 3 (parallel to the drive belt 3), and driven by the fixing member 5 at a position near the door arm 7 (position near the door arm 7). It is fixed to the belt 3. The position close to the door arm 7 is, for example, a position where the wire harness 4 pulled out from the door arm 7 reaches the drive belt 3 at the shortest distance, etc., without causing the wire harness 4 pulled out from the door arm 7 to bend. This position can be fixed to 3.

  On the other hand, when the slide door in FIG. 2 is fully open, the wire harness 4 is drawn into the storage portion 6 from the fixing port 65 and draws an arc of approximately 90 degrees along the guide member 62 and the side wall 64. It is curved and pulled out of the storage unit 6.

  Next, an example of the operation of the above-described harness installation structure 1A will be described below. First, in a state where the slide door is closed, the wire harness 4 is curved in a circular arc, folded back, and stored in the storage portion 6 (FIG. 1). At this time, the wire harness 4 is curved so as to draw an arc of approximately 180 degrees or less. When the slide door is closed and an instruction signal to open the slide door is input from the open / close switch to the control unit, the control unit drives the rotational drive device 22 to rotationally drive the drive belt 3 in the clockwise direction. When the drive belt 3 is rotationally driven and the slide door side of the drive belt 3 moves backward, the wire harness 4 is also pulled backward in synchronization with the drive belt 3 and the entire wire harness 4 moves rearward.

  The wire harness 4 enters and is stored in the storage portion 6 while maintaining the initial arc shape due to its own rigidity. In particular, the flat cable-like wire harness is less likely to buckle in the vertical direction, and the original arc shape is likely to be maintained. The wire harness 4 is stored in the storage portion 6 along the guide member 62 starting from the fixing port 65. Thus, the bending between the portion fixed to the fixing port 65 in the wire harness 4 and the curved portion is restricted, and the extra long portion of the wire harness 4 is stored in the storage portion 6 without breaking the arc shape. It will be done (Figure 3). When the slide door is fully open (FIG. 2), the wire harness 4 is disposed along the guide member 62 and the side wall 64 in the storage portion 6. At this time, the wire harness 4 is curved by drawing an arc of approximately 90 degrees.

  When the slide door is fully open and an instruction signal for closing the slide door is input from the open / close switch to the control unit, the control unit drives the rotation drive device 22 to rotate the drive belt 3 in the counterclockwise direction. . When the drive belt 3 is rotationally driven and the drive belt 3 located on the slide door side moves forward, the wire harness 4 is also pulled forward in synchronization with the drive belt 3 and the entire wire harness 4 moves forward.

  Even when the sliding door is closed, since the wire harness 4 is fixed by the holding member 63 at the fixing port 65, when pulling the wire harness 4 starting from the portion fixed by the fixing member 5 in the wire harness 4 The arc is drawn naturally, it is curved and turned back, and it is maintained in an arc shape of about 180 degrees even when the slide door is closed. That is, the extra-long portion of the wire harness 4 is stored in the storage portion 6 in a state of being drawn in an arc of approximately 90 degrees or more and approximately 180 degrees or less.

  The harness wiring structure 1A according to the present embodiment extends in the sliding direction of the door arm 7, and includes a drive belt 3 for driving the same and an extra length portion of the wire harness 4 for moving in synchronization with the movement of the drive belt 3. The wire harness 4 is fixed to the drive belt 3 at a position closer to the door arm 7 and fixed to a fixed port 65 at a position closer to the vehicle 2, and the wire harness 4 has an extra length The portion is curved so as to draw an arc of about 90 degrees or more and about 180 degrees or less in the storage unit 6. Furthermore, in the harness arranging structure 1A according to the present embodiment, the storage portion 6 at least includes the guide member 62 disposed in parallel with the moving direction of the drive belt 3, and the guide member 62 is the wire harness 4. The deflection between the portion fixed to the fixing port 65 and the curved portion is restricted. With such a configuration, the harness wiring structure 1A according to the present embodiment expands and contracts as the door arm 7 is driven, and the extra-long portion of the wire harness 4 that moves moves into the storage section using the driving force of the door arm 7. Can be stored in six. For this reason, since it is not necessary to provide another winding member in order to absorb the excess length of the wire harness 4, the number of parts required for the excess length absorption of the wire harness 4 can be reduced.
