A buffering part 34 is formed by turning an end side of a wiring harness 30 in a U-shape, and by detachably holding a neighbor of an end of the wiring harness 32 with a retainer 29 of a protector 24 disposed on a middle of the wiring harness 33 . A circular portion of the buffering part 34 can work as a buffer. The buffer performance of the buffering part 34 depends on flexibility and resiliency of a corrugate tube 25 and on a circular shape formed between a holding position of the retainer 29 and the neighbor of the end of the wiring harness 32.
1. A wiring harness comprising:
a circular portion, acting as a buffer, formed by a corrugate tube exiting a protector around the wiring harness and then turned into a U-shape by detachably holding an end of the corrugate tube including the wiring harness or a neighbor of the end of the wiring harness against protector in order to retain the corrugate tube in the U-shape, the end of the corrugate tube held against the protector, an end opposite to that which the corrugate tube exits the protector, and
a retainer fixedly attached to the protector to detachably hold the end of the corrugate tube including the wiring harness or the neighbor of the end of the wiring harness, the retainer formed on the protector prior to a portion where the corrugate tube exits the protector.
2. The wiring harness as claimed in claim 1 , further comprising:
a plurality of high-voltage electrical power lines extending from a front side of an inner vehicle body of a hybrid vehicle or an electric vehicle through an under floor of the vehicle at an outside of a vehicle frame to a rear side of the inner vehicle body for connecting a battery and an inverter or for connecting a motor and an inverter;
a protector for protecting together middle parts of the high-voltage electrical power lines; and
the corrugate tube composing the buffer.
3. The wiring harness as claimed in claim 1 , further comprising:
a plurality of high-voltage electrical power lines extending from a front side of an inner vehicle body of a hybrid vehicle or an electric vehicle through an under floor of the vehicle at an outside of a vehicle frame to a rear side of the inner vehicle body for connecting a battery and an inverter or for connecting a motor and an inverter;
a protector for protecting together middle parts of the high-voltage electrical power lines; and
the corrugate tube composing the buffer.
