In a vehicle body, a body portion having a base end side portion is engaged with a plate-shaped member and extending along the plate-shaped member toward the leading end side, and a removal-preventing portion for preventing the wire harness stored in a space between the plate-shaped member and the body portion from being removed from the leading end side of the body portion. The wire harness stored in the space is prevented from being removed at the leading end side of the body portion by the removal-preventing portion pivoting according to the storage. By a series of rotations of the removal-preventing portion up to the storage, a pivotal body upper portion of the removal-preventing portion disposed at a high position in a height direction extending from the plate-shaped member is moved to a lower position, thereby reducing the height of the entirety of the routing structure.
