[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for mounting a wire harness, which is routed in a vehicle such as an automobile, to a mounting member fixed to a vehicle body, for example, in the vicinity of a route through which the wire harness is routed. The present invention relates to a wire harness mounting structure for mounting to a mounting member such as an instrument panel.

[0002]

2. Description of the Related Art As a conventional wire harness mounting structure, for example, the one shown in FIGS. 8 and 9 has been filed by the present applicant. In this mounting structure, a state in which the wire harness 1 is tightened integrally with a resin component such as an air-conditioning duct 3 fixed to a mounting member such as an instrument panel 2 near the route in which the wire harness 1 is routed. Is provided. The band clip 4 has a flexible elongated band portion 5 extending from the air conditioning duct 3, and a base end 5 a of the band portion 5.
Plate 6 fixed to instrument panel 2 integrally with
And a band retaining portion 7 which rises in a gate shape so as to form an insertion hole 7a through which the band portion 5 is inserted. A large number of ridges 8 are provided on the surface of the band portion 5 substantially in parallel along its longitudinal direction, and the ridges 8 are provided on the upper inner surface of the band fastening portion 7 so as to allow movement of the band portion 5 only in the tightening direction. An engaging portion 7b is provided for engaging the projection 8 and engaging the ridge 8 with respect to the movement of the band portion 5 in the loosening direction. Then, after the band portion 5 is wound around the outer periphery of the wire harness 1, the ridge 8 is locked by the locking portion 7b in a state where the band portion 5 is inserted into the insertion hole 7a of the band fastening portion 7 and tightened. I have.

[0003]

However, in the above-mentioned conventional example, after the band portion 5 is wound around the outer periphery of the wire harness 1, the tip portion 5a of the band portion 5 is inserted into the insertion hole 7a of the band fastening portion 7. In addition, since the band fastening portion 7 is near the wire harness 1, the distal end portion 5a straightly enters the insertion hole 7a from obliquely above. Therefore, as shown in FIG. 9, the distal end portion 5a is easily caught in the die-cut hole 9 of the plate portion 6 formed below the band fastening portion 7, and it is difficult to perform the work of fastening and holding the wire harness 1 with the band portion 5. .

[0004] The present invention has been made in view of such circumstances, and an object thereof is to provide a wire harness mounting structure that improves workability and work efficiency when tightening and holding a wire harness. It is.

[0005]

According to a first aspect of the present invention, a wire harness is integrated with a resin component fixed to a mounting member near a route for arranging the wire harness. At least one set of band clips to be held in a tightened state is provided, and the band clips are attached to a mounting member integrally with a flexible elongated band portion extending from a resin component and a base end of the band portion. From the plate to be fixed, it consists of a band retaining part that rises in a gate shape to form an insertion hole through which the band part penetrates, and a number of ridges are provided on the surface of the band part almost in parallel along its longitudinal direction And engaging the ridge on the upper inner surface of the band retaining portion so as to allow movement of the band portion only in the tightening direction, and locking the ridge against movement of the band portion in the loosening direction. Locking part In the wire harness mounting structure, the band is wound around the outer periphery of the wire harness, and then inserted into the insertion hole and tightened, and the ridge is configured to be locked by the locking portion. The distal end portion was provided with an introduction portion which was bent so that when the distal end portion was inserted into the insertion hole of the band fastening portion, the distal end portion escaped upward from a die hole of a plate portion formed below the band fastening portion. It is characterized by the following. According to this configuration, when inserting the distal end portion of the band portion into the insertion hole of the band retaining portion, the bent introduction portion provided at the distal end portion is inserted into the insertion hole in a posture substantially parallel to the plate portion. This allows the introduction portion to pass through the insertion hole without causing the leading end of the introduction portion to be caught by the mold release hole of the plate portion. After this, the wire harness is tightened with the band by pulling the introduction part that has passed through the insertion hole, and the ridge of the band is locked with the locking part of the band holding part in this tightened state, and the wire harness is held in the tightened state Is done.
