线束
摘要：
一种线束，包括具有管状的外部构件。该外部构件包括形成为柔性波节管状的柔性管部以及直管部。直管部与柔性管部连续地形成，以将导电路径布置为直线状，并且直管部具有非波节管状。在柔性管部与直管部之间的连续部包括锥状部，该锥状部形成在外部构件的整个周向上，从而减小连续部中的应力集中。锥状部的内周表面和外周表面包括斜面，该斜面连接柔性管部的波节凸部的顶部与直管部，或者该斜面连接柔性管部的波节凹部的凹槽底部与直管部。
摘要（英）：

A wire harness includes an exterior member having a tube shape. The exterior member includes a flexible tube part formed in a flexible bellows tube shape and a straight tube part. The straight tube part is formed continuously with the flexible tube part so as to arrange the conductive path straight and has a non-bellows tube shape. A continuous portion between the flexible tube part and the straight tube part includes a tapered portion formed in a whole peripheral direction of the exterior member so as to reduce stress concentration in the continuous portion. An inner peripheral surface and an outer peripheral surface of the tapered portion include slopes connecting a top of a bellows projection of the flexible tube part and the straight tube part, or connecting a groove bottom of a bellows recess of the flexible tube part and the straight tube part.
