Since the nut of the above-mentioned Patent Document 1 can slide the nut in the longitudinal direction of the clip, the nut position can be finely adjusted with respect to the position of the bolt insertion hole. However, in this case, even if the position of the bolt insertion hole should be originally the same position, when the position is slightly shifted due to poor dimensional accuracy and assembly accuracy, the position can be adjusted by sliding. It is a thing.
Originally, when the position of the bolt insertion hole is different, it is necessary to prepare a clip nut suitable for each position.
Further, since there is no means for positioning the nut at a predetermined position facing the bolt insertion hole provided in the plate material, in actual use, the screw shaft of the bolt inserted into the bolt insertion hole is slidably displaced. There is a problem in terms of workability because it may abut against the seat surface of the nut and not properly fit into the screw hole.

The clip nut of Patent Document 2 is configured so that the same clip nut can be applied to plate materials having different bolt insertion holes by providing a long hole provided in the first piece. However, the nut is in a state in which it can slide freely with respect to the first piece of the clip, and is in a state in which the relative positional relationship with each other is not determined, and workability is poor. Further, since the nut is slid, the structure is complicated and the cost is high. If the resistance when sliding the nut is large, setting may take time or the setting may not be possible, and the burden on the operator is large.

In order to sandwich the plate material 21 between the first piece 3 and the second piece 4, the clip portion 2 has the same length as the first piece 3 and the second piece 4, or the second piece 4 as the second piece 4. The length is slightly longer than one piece 3. The clip portion 2 is made of a spring stainless steel material, and the nut holding member 10 is made of a non-spring steel stainless steel material, reducing the use of expensive spring steel materials. At the tip of the nut holding member 10, a guide part 11 formed by being slightly bent outward is provided, and at the tip of the second piece part 4, a guide part 41 formed by being slightly bent outward is provided. The guide portions 11 and 41 serve as guides for extrapolation to the plate member 21 and facilitate insertion. In addition, the second piece 4 is formed to extend slightly inward (in a direction close to the first piece 3) from the bent portion 5 in a free state, and the distance from the first piece 3 is gradually increased. It has become narrower. As a result, a spring force can be applied when the plate material 21 is sandwiched, and even plates having a slightly different thickness can be used in common.

The engagement between the first piece 3 and the nut holding member 10 will be described with reference to FIG. The nut holding member 10 is disposed at the inner position of the first piece 3, and the first piece 3 is overlapped on the outer side. A through hole 13 through which the rivet 17 as the shaft member is passed is provided in the nut holding member 10, and a through hole 31 through which the rivet 17 as the shaft member is passed is provided in the first piece 3 concentrically with the same size as the through hole 13. ing.
