In particular, the wiring tool 1 is suitable in that the work toward the back side of the base member 10 is not required to support the electric wire 9 on the base member 10.

  In addition, since the retaining mechanism of the erection member 20 is configured by a hook portion formed in a part of the erection member 20 and the edge of the retaining hole 13, the erection member 20 does not come out of the retaining hole 13. The work to do is easy. The retaining hole 21, the overhanging portions 21A, 21B, and 21E, the protruding portions 21C and 21D, and the insertion piece 21F are examples of the hooking portion.

  Further, in the retaining mechanism, a plurality of hanging portions are formed side by side at a plurality of locations of the erection member 20 for each corresponding retaining hole 13, so that the length of the portion surrounding the electric wire 9 in the erection member 20 can be reduced. It becomes possible to adjust according to the thickness of 9. Therefore, the length of the erection member 20 is adjusted so that the electric wire 9 is sandwiched between the erection member 20 and the wiring part 11 of the base member 10, and the work of fixing the electric wire 9 to the wiring part 11 becomes easy.

  In addition, the erection member 20 is less flexible and less bent as the width thereof is larger. However, it is possible to bend the erection member 20 so as to straddle the electric wire 9 by forming the bending target portion 23 configured to bend more easily than other parts along the line crossing the erection member 20. It becomes easy. Such an effect of the bending target portion 23 becomes particularly remarkable when, for example, the width of the erection member 20 is formed to protect the electric wire 9 over a wide range.

  In addition, since the base member 10 includes the guide portion 15 formed by vacuum forming, the work of arranging the electric wire 9 along the wiring portion 11 becomes easy. Moreover, the apparatus and process which form the guide part 15 by vacuum forming are suitable at the point which can be implement | achieved easily rather than the apparatus and process which shape | mold the resin member which has the guide part protruded by injection molding.

  Moreover, since the mark 17 indicating the orientation of the wiring tool 1 is written on a part of the base member 10, it is easy to attach the wiring tool 1 in the correct orientation.

<Others>
In each of the embodiments described above, the electric wire 9 is protected by the wiring portion 11 on one surface thereof, and the surface opposite to the wiring portion 11 is mainly protected by the erection member 20B of the second electric wire support portion 100B. Is done.

  However, when it is sufficient that the electric wire 9 is protected by the wiring portion 11 on one side, the second electric wire support portion 100B is replaced with the first electric wire support portion 100A in the wiring tool 1, or the first electric wire support portion. It is also conceivable that 100A is omitted. It is also conceivable that the electric wire 9 is supported by the first electric wire support portion 100A or the second electric wire support portion 100B in a state covered with a protective tube such as a corrugated tube.

  It is also conceivable that the base member 10 of the wiring tool 1 does not have the guide portion 15. The base member 10 that does not have the guide portion 15 is a flat member. In this case, the base member 10 can be used as two types of base members 10 having the opposite positional relationship such as the wire support portion 100 depending on which side of the front and back the electric wires 9 are arranged. For example, when the positional relationship of the electric wires 9 is symmetrical between a wire harness disposed below the driver's seat of the vehicle and a wire harness disposed below the passenger seat, the base member without the guide portion 15 is provided. 10 and the erection member 20 can be used for both the driver's seat and the passenger seat.

  Moreover, in the wiring tool 1, the wiring part 11 of the base member 10 is a flat part. However, it is also conceivable that the wiring part 11 is a groove formed by vacuum forming or the like.
