Abstract

The invention provides a wire harness capable of suppressing deviation of an arrangement state and preventing interference. The wire harness (21) is provided with a wire harness trunk line (22) and arotating jig (25). The wire harness main line (22) passes through a wire harness lead-out portion (29) of the electrical connection box and a protector (24) fixed away from the electrical connection box and is arranged between the wire harness lead-out portion and the protector. The rotary clamp (25) is arranged in the middle of the wire harness main line (22). The wire harness main line (22) is provided with bendable bent parts (33) in a first section (S1) between the first fixed part (30) and the rotary clamp (25) and a second section (S2) between the second fixed part (31) and the rotary clamp (25). In addition, the wire harness trunk line (22) is formed in an arrangement shape bent substantially in an S-shape as a whole from the first fixing part (30) to the second fixing part (31). Inaddition, the wire harness trunk line (22) is provided with a hard pipe (26) (hard part) which is harder than the bent part (33) and is approximately linear in shape in the first section (S1).

Description

technical field [0001] The present invention relates to a wire harness arranged at a predetermined position of an automobile. Background technique [0002] For example, a battery, an alternator, a relay box, and the like are mounted in an engine room of an automobile. The output terminals of the battery and the output terminals of the alternator are connected to the relay box. Then, the relay box and the relay box are also connected to a junction box in the vehicle interior via a wire harness provided at the end (see, for example, Patent Document 1 below). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2014-97709 [0006] Taking the above-mentioned relay box and wiring harness as an example, the wiring harness is generally bent into a three-dimensional shape for arrangement. refer to Figure 5 and Figure 6 Specifically, reference numeral 1 denotes a relay box (electrical connection box), r...
