Abstract: A method of manufacturing a branch protector includes a component setting step of supporting a protector sheet of a branch protector in a floating state from a jig base on a jig pin erected on the jig base, and an assembling step of assembling a wire branch portion to the protector sheet.

Abstract: A wire harness includes a power trunk line, a power branch line, a communication trunk line, and a communication branch line. The power trunk line is connected to a power source mounted on a vehicle and extend in a longitudinal direction of the vehicle. The power branch line branches off from the power trunk lines and extends in a direction intersecting with the longitudinal direction. The communication trunk line is arranged along the power trunk lines or also serves as the power trunk lines. The communication branch line branches off from the communication trunk line and extends in a direction intersecting with the longitudinal direction.

Abstract: An object of the present invention is to provide a wiring harness attaching structure aiming at improvement in attaching workability and aiming at thinning of a vehicle door. Provided is a wiring harness attaching structure for attaching a wiring harness to a vehicle interior outer surface of a door trim constituting a vehicle door. The wiring harness is a flat cable whose width dimension is longer than a thickness dimension, is located inside a structure body containing gas phase, and is provided integrally with the structure body containing gas phase. The structure body containing gas phase is attached along the vehicle interior outer surface of the door trim. The wiring harness is attached to the door trim together with the structure body containing gas phase.

Abstract: The present invention provides an automotive soundproofing material capable of providing a high sound absorption performance throughout a wide frequency band. In the automotive soundproofing material, flexible-porous body and sheet-shaped body are formed in a multi-layered structure, and the sheet-shaped body is comprised of a plurality of through holes formed therethrough.
