Further, in the cording material fixing structure 100 of the protector 1 of the present embodiment, the concave portion 12 is formed by projecting the concave portion 12 from the bottom surface portion 12a to the side opposite to the accommodation space portion 11 side in the width direction, and the plate-shaped portion 15. It has a through hole 15b that penetrates the plate-shaped portion 15 and through which the band portion 101b is inserted in a fixed state. The cutout portion 13 extends from one end in the vertical direction of the bottom surface portion 12a to the base end 15a side in the width direction of the plate-shaped portion 15. As a result, by inserting the band portion 101b through the through hole 15b, the binding member 101 can be temporarily held on the protector 1 side during the assembly work. As a result, the worker can easily perform the bundling work. Further, when the binding member 101 is tightened by pulling the rear end 101d of the band portion, the plate-shaped portion 15 restricts the movement of the head portion 101a, so that the binding member 101 does not rotate in the circumferential direction of the wiring member W. Can be regulated. As a result, the binding work can be improved. Further, the plate-shaped portion 15 serves as a receiver when the operator holds down the head portion 101a when the binding member 101 is tightened by pulling the rear end 101d of the band portion, so that the head portion 101a can be moved. It can be easily regulated.

The wiring material fixing structure 100 of the protector 1 of the above embodiment can be used for other than fixing the wiring material W and the protector 1. For example, in the electrical junction box, the wiring structure of the embodiment may be used to fix the housing and the wiring material.
