Offers fixing clips.
[0008]
With the above configuration, when the clip is fixed to the material to be fixed, the stopper portion provided at the tip of the flat plate portion is brought into surface contact with the material to be fixed, thereby preventing rotation of the clip. Accordingly, it is possible to prevent the distal end portion of the clip from repeatedly interfering with the material to be fixed, and to prevent damage to the material to be fixed. Further, by preventing the rotation of the clip, it is possible to prevent the wire harness from swinging left and right, so that it is possible to prevent the wire harness from being damaged by interfering with an interfering material such as a fixed member.
Further, since the clip is positioned and held on the material to be fixed by the stopper portion, the operation of fixing the clip can be facilitated.
Furthermore, since the rotation of the clip can be prevented not only when the clip is fixed to the material to be fixed but also after fixing, the bolt is not loosened by the rotation of the clip, and the clip is fixed to the material to be fixed. It can be securely held.
[0009]
The one flat plate portion is a first flat plate portion extending linearly from the tip of the circular arc portion, while the other flat plate portion is a second flat plate portion extending in a direction orthogonal to the distal end of the circular arc portion,
The stopper portion protrudes from the end of the second flat plate portion and is provided with the round hole-shaped bolt hole, while the first flat plate portion is formed by cutting out the U-shaped or oblong bolt hole cut out from the front end. Prepare,
The stopper is brought into surface contact with the material to be fixed and abutted against the material, and the first flat plate is bent to overlap the second flat plate.
