Description

  The present invention relates to a linear object fixing structure including a linear object composed of a plurality of linear bodies and a fixing member that binds the linear object and fixes the linear object to a fixed portion.

  Many electronic devices are mounted on automobiles, and electronic devices are connected to automobiles and other electronic devices via wire harnesses. The wire harness includes an electric wire bundle composed of a plurality of electric wires and a connector attached to each end of the electric wires constituting the electric wire bundle. The wire harness and the electronic device are connected when the connectors included in the wire harness and the electronic device are fitted to each other, and the wire harness transmits power, a control signal, and the like to the electronic device.

  Such a wire harness is routed on a panel constituting the vehicle body, for example. The wire bundle is fixed to the panel by a fixing member and routed to the panel (see, for example, Patent Document 1). The fixing member first fixes the electric junction box to the panel, and then the electric wire bundle is attached, and the electric wire bundle is fixed to the panel to route the electric wire bundle along a desired wiring path.

  It is also possible to route the wire bundle by attaching a fixing member to the wire bundle in advance and fixing the fixing member to the panel. Such a fixing member includes a binding part that binds the electric wire bundle and a fixing part that is connected to the binding part and is fixed to the panel. The fixing portion protrudes outward from the binding portion.

  The fixing member is attached to the electric wire by arranging the binding portion at a desired position in the longitudinal direction of the electric wire bundle and at the position (orientation) where the fixing portion protrudes toward the panel in the circumferential direction of the electric wire bundle. However, in order to attach the fixing member to the desired position of the wire bundle in this way, a wire harness assembling apparatus has been conventionally used, and there has been a problem that the assembling process becomes complicated.

In order to solve such a problem, for example, it is conceivable that a binding member such as an adhesive tape is wound around a portion to which the fixing member of the wire bundle is attached in advance as a mark. FIG. 6 shows the wire bundle 102 bound by the binding member 104. The wire bundle 102 includes three wires 121 in the illustrated example, and the bundling member 104 binds these three wires 121. By attaching the fixing member 103 to the outer surface of the binding member 104, the binding portion 131 can be easily arranged at a desired position in the longitudinal direction of the wire bundle 102.
Japanese Patent Laid-Open No. 11-252742

  However, since the binding member described above does not serve as a mark of the position of the fixing portion in the circumferential direction of the wire bundle, there is a problem that it is difficult to arrange the fixing portion so as to protrude toward the panel.

  Also, without attaching the fixing member directly to the wire bundle, a fixing member arranged in advance at a desired position is attached to a protector consisting of a bowl-shaped main body part and a cover part covering the main body part. Although it is possible to route the electric wire through the electric wire, a protector is required as a separate part, and there is a problem that the cost increases due to the increase in the number of parts and the number of assembly processes increases.

  The present invention aims to solve such problems. That is, the present invention is to provide a linear object fixing structure in which a fixing member can be easily attached at a desired position and orientation of the linear object.
