The present invention improves work to engage a connector on a terminus of a wire harness drawn out through a protector. A circular engagement hole is provided on a bottom wall within the protector, the engagement hole positioned away from an outlet for the wire harness. An engagement portion of a band clip fastened to the wire harness is inserted into and rotatably engaged with the circular hole. The wire harness drawn out through the wire harness outlet is capable of rotating around the engagement portion of the band clip as a pivot point.
