Abstract

A wire harness includes a wire harness main body having at least one electric wire and a protection material formed by hot pressing a nonwoven material wrapped more than one time around a circumference of at least a portion in a longitudinal direction of the wire harness main body. A slimmed portion is provided to at least one end of the protection material, the slimmed portion being thinner than a middle portion of the protection material so that a portion where an external surface and an internal surface of the nonwoven material make contact with each other is entirely joined in a circumferential direction on a periphery of the wire harness main body.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to Japanese Application No. 2011-279927 filed on December 21, 2011, the entire disclosure of which is hereby expressly incorporated by reference. technical field [0003] The present invention relates to a technology for protecting electric wires installed in vehicles and the like. Background technique [0004] Prior art 1 discloses a technique of performing hot pressing to cure a nonwoven fabric covering electric wires. [0005] Prior Art 1: Japanese Patent Laid-Open Publication No. 2011-160611 [0006] Depending on the purpose of use, there are cases where the nonwoven fabric is heat-pressed to maintain a certain degree of softness. Such a nonwoven fabric retaining a certain degree of softness can be obtained by hot-pressing a nonwoven fabric with a relatively low compressibility at a lower temperature or for a shorter period of time. [0007] However, in the p...
