WIRING MEMBER

In a base member arrangement section, a plurality of wire-like transmission members are divided into at least a first wire-like transmission member bundle and a second wire-like transmission member bundle, and the cover member is fixed to the base member at positions on both sides of the first wire-like transmission member bundle and the second wire-like transmission member bundle and a position between the positions on the both sides to cover the first wire-like transmission member bundle and the second wire-like transmission member bundle. In a non-base member arrangement section, the plurality of wire-like transmission members include a large bundle part where the first wire-like transmission member bundle and the second wire-like transmission member bundle are bundled together.
