Abstract

A wire arrangement body includes: a wire arrangement groove portion of a tank shape that has a bottom wall portion and both side wall portions; a lid portion that is rotatably connected to one side wall portion of the wire arrangement groove portion through a hinge and covers the wire arrangement groove portion so as to seal a groove opening of the wire arrangement groove portion; and an engagement portion that causes the lid portion to engage with the other side wall portion of the wire arrangement groove portion when the lid portion covers the wire arrangement groove portion. The wire arrangement body is provided so that a center position of the hinge and a center position of the engagement portion are aligned in parallel with a width direction of the wire arrangement body.
