Description

This invention relates to a protector for protecting wire harnesses routed in vehicles, a connecting member for connecting a restricting exterior member that restricts the wire harness according to the routing path and a connecting target member, a protector with a connecting target member composed of a connecting target member and a protector, and a wire harness with a protector in which a portion of the wire harness is protected by the protector. For example, wire harnesses that electrically connect electrical equipment installed in a vehicle are routed within the vehicle with protectors and other components attached to regulate the routing to match the vehicle's shape and prevent damage from interference with other components. For example, the protector disclosed in Patent Document 1 is composed of a resin molded product that fits onto the end of a corrugated tube formed in a bellows shape, and it regulates and protects the routing of wire harnesses. However, since the protector described in Patent Document 1 is a resin molded product, in order to regulate the wire harness route along two-dimensional or three-dimensional routing paths to match the diverse shapes of vehicles, it was necessary to individually mold protectors with shapes corresponding to each routing path.
