ROUTING STRUCTURE FOR PROTECTIVE TUBE FOR POWER SUPPLY

The present invention is to smoothly bend a wire harness equipped with a protection tube between a sliding structure body and a fixed structure body without causing buckling or the like and to prevent interference with the fixed structure body. A wire harness equipped with a bendable protection tube is swingably arranged between a fixed structure body and a sliding structure body, a rigidity imparting portion is formed on a side surface of an end portion of the protection tube in the fixed structure body side, and the end portion of the protection tube constantly extends in a linear manner by the rigidity imparting portion when the sliding structure body is opened or closed. The rigidity imparting portion is configured by a uniformly shaped portion on a tip side of the end portion of the protection tube and a gradually-changing shaped portion on a base end side of the end portion.
