The meandering state of the meandering part 33 becomes tight as shown in the figure (the bending radius of each bending part 34 decreases and the length in the direction of the arrow P decreases. In other words, the bending state of each bending part 34 becomes tighter).

In FIG. 5, when a door (not shown) is closed and the door is closed, the movable wire of the flat wire harness 22 is released from the pulled state. At this time, the restoring force generated in each curved portion 34 acts, and the meandering portion 33 that has been contracted until then returns to its original state.
The meandering state of the meandering part 33 becomes loose as shown in the figure. Along with this, the movable end side drawer 32 is smoothly pulled back into the housing 23 through the outlet 30 of the side wall 28 on the movable end side (left side in the figure) (retracted in the arrow Q direction. It is automatically and smoothly pulled back (pulled in) by the restoring force). In addition, a continuous portion of the meandering portion 33 and the movable end side drawer 32 and each of the curved portions 34 slide the bar member main body 35 in the direction of the arrow Q (sliding while maintaining the meandering shape). .

The flat wire harness excess length absorbing device 21 of the present invention as the first embodiment described above with reference to FIGS. 1 to 5 has the following effects. That is, since the restoring force generated in each bending portion 34 is used, the movable end side drawer 32 of the flat wire harness 22 can be automatically pulled in without providing a special mechanism. Further, the retraction is performed by the harness protector 5 and the guide roller 15 described in the conventional example.
(See FIG. 24).
It can be done smoothly. Further, since the number of constituent members is small and the configuration is simplified, the manufacturing cost can be suppressed. Furthermore, the size of the device itself can be reduced as described above.

The meandering part 33 and the movable end side drawer 3
A bending radius regulating member 45 as shown in FIG. 6 may be positioned at a portion continuous with the portion 2 to restrict the bending radius of the continuous portion. The bending radius regulating member 45 is formed in a columnar shape having the minimum bending radius or a diameter larger than the minimum bending radius (it is sufficient if the bending radius restricting member 45 has an arc 46 that comes into surface contact with the flat wire harness 22). The rod member main body 35 is inserted, and the rod member main body 35 can be slid. On the other hand, a continuous portion between the meandering portion 33 and the movable end side drawer 32 may be made to correspond by bending as shown in FIG.
