を第４図、第５図に示す。[Prior Art] In recent years, with the diversification of applications, the production form has shifted from mass production of small variety to small quantity production of many variety, but in this process, rationalization and standardization of processes and dimensions have been called for. The tap hole processing has also been reviewed according to this trend. For example,
Considering the case of assembling a frame of a communication device or a computer or attaching an object such as a panel to the frame, tap holes for screwing bolts or screws are required. In order to screw this tap hole, in the case of manual work,
Scribing according to the drawing, punch at the intersection of scribing,
It was necessary to perform a complicated work such as drilling a pilot hole with a drilling machine according to the punch hole, using the first tap to the third tap in order to raise the tap, and screwing the tap hole. . Even if an NC processing device is used, basically it is necessary to drill a pilot hole according to the program and then to make a tap, and the tapping work takes a considerable weight with respect to the total working time. Had occupied. In addition, drilling and tapping belong to machining as a work item, and the labor cost per unit time is higher than that of sheet metal processing, and the conventional processing method has been a major obstacle to product cost reduction. Furthermore, if the above-mentioned standardization is promoted, it becomes necessary to use a lot of common members. Therefore, regardless of whether it is necessary or not, it is necessary to form a large number of tap holes at regular intervals, and a large number of useless tap holes are formed. Must. Therefore, it has been considered that the through holes for the bolts are punched out at a constant interval in the sheet metal working so that the tap holes can be easily set at the required positions by using a clip nut. Examples of this type include JP-A-49-41235 and JP-A-62-10031.
8 and Japanese Utility Model Laid-Open No. 63-4420, examples of which are shown in FIGS. 4 and 5.

移動が規制されるように構成されている。The upper plate 21 and the lower plate 27 that are elastically folded back in a substantially U shape are used to hold the nut 26 at the mounting position of the component.
A bolt insertion hole 28 is formed substantially at the center of the upper plate 21, and parallel cuts 22a, 22b are formed in the upper plate 21 at a position corresponding to the bolt insertion hole 28 of the lower plate 27 at regular intervals. The center of the center part of the upper plate 21 sandwiched by the 22b is cut into the above-mentioned notches 22a, 22b.
A pair of left and right locking melon pieces 23a, 23b are formed by cutting in the direction orthogonal to and standing upright, and a nut 26 is arranged between the pair of locking melon pieces 23a, 23b and the locking claw pieces 23a, The upper portion of the nut 23b is bent in the opposite direction so as to hold the nut 26, and one side of the nut 26 not held by the locking claw pieces 23a, 23b is bent upward. Thus, the other side is configured to be restricted from moving in any direction by the claw piece 24 tilted upward.

る。[Problems to be Solved by the Invention] However, since the conventional clip nut has the above-mentioned configuration, some problems remain when it is used for assembling construction members or for repairing when the thread of the tap hole is deformed. It became clear that it was done. That is, when a panel or the like is attached to a frame of a building member with bolts, the positions of the bolt attachment holes from the frame end may be different from each other, and the clip nut cannot be used. Further, this point will be described with reference to FIGS. 6 and 7.

れることになる。FIG. 6 and FIG. 7 are a plan view and a sectional view of an essential part showing a case where a clip nut is used to mount the frame. When the panel 33 is attached to the adjacent frames 31 and 32 with the bolts 34 and a step G occurs between the frame 31 and the frame 32 due to an engagement with other components, the frames 31 and 32 and the panel 3 are separated.
The heights H 1 and H 2 of the bolt mounting holes 33a and 33b of 3 are displaced by the step G.

い。At this time, since the nut nut 20 has a constant nut mounting height H 0 , the bolt mounting holes 33a of the frame 31 and the panel 33 are fixed.
Applicable to the frame 32 and panel 33 bolt mounting holes
It is not possible to use the same clip nut for 33b because the nut mounting height does not match. Therefore, several types of clip nuts with different nut mounting heights H 0 must be prepared.
本考案の目的とするところは、フレーム等の取付位置高

する。[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention bends at least a part of the upper plate facing in the long side direction upward to form a pair of left and right and raises the nut. It is characterized in that a locking claw piece that movably holds the upper plate in the long side direction and a holding means that locks and holds the nut at a predetermined position of the upper plate are provided.

ツプナツトで対応可能とすることができる。[Operation] Since the clip nut according to the present invention has the above-described structure, the pair of left and right engaging claw pieces bent and bent upward from the periphery of the long side of the upper plate are placed on the upper surface of the upper plate. Since the nut is held so as to be movable in the long side direction of the upper plate, it is possible to arbitrarily select the position of the nut.
Since the nut can be fixed at the selected position by the holding means, the nut will not fall off the upper plate,
Therefore, even one kind of clip nut can be used for mounting holes having slightly different dimensions.
