Abstract

Provided are an electrical wire exterior body and wire harness equipped with the exterior body that can reduce vibration sound generated by vibration of an exterior body attached to a vehicle, etc., and vibration of the wire harness in the exterior body, the vibrations being caused by vibration of the vehicle, etc. This electrical wire exterior body is formed by bending a resin sheet and is fitted to the outer circumference of an electrical wire, the electrical wire exterior body being provided with a plurality of walls that extend along the extending direction of the electrical wire and form a storage section for storing the electrical wire, wherein at least one of the walls is provided with a projection that projects from the wall.

Description

technical field [0001] The present invention relates to a sheath for electric wires attached to the outer periphery of electric wires in order to protect electric wires such as a wire harness, and a wire harness having the sheath. Background technique [0002] Conventionally, wire harness sheaths are used to attach and fix the wire harness to a vehicle body or the like. In addition, by storing the wire harness in the housing portion of the sheath, the sheath functions to adjust the route of the wire harness and to protect the wire harness. On the other hand, due to the vibration of the vehicle or the like, the sheath of the vehicle or the like and the wire harness mounted in the sheath may vibrate to generate vibration sound. From the standpoint of ride comfort of vehicles and the like, it is necessary to reduce vibration noise. [0003] For example, suppression of vibration noise can be expected by preventing the wire harness from rattling in the sheath. Therefore, a mea...
