BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a clamp for supporting a pipe, an electric cord, a wire such as an electric cable or a wire for various operations, a rod-shaped object, and more particularly, to a groove provided on a substrate. The present invention relates to a clamp that constantly restricts a built-in nut body to a predetermined position by arcuate nut body holding pieces provided to face each other in the groove.

[0002]

2. Description of the Related Art Clamps are attached to stud bolts that are conventionally provided upright on a vehicle panel in order to fix pipes, electric cords, and the like installed on a vehicle such as a passenger car to a vehicle panel for wiring and piping. A technique of assembling and holding pipes, cords and the like by holding grooves provided in the clamp is used. To attach the clamp to this stud bolt, insert the stud bolt into the stud bolt insertion hole provided in the clamp, then fit a nut from the stud bolt tip and tighten the clamp between the bolt base and the nut. It is done by doing. However, the attachment of the clamp to such a stud bolt is often performed manually due to its nature, and an error may also occur in the standing position of the stud bolt. It has been difficult to accurately and quickly insert a stud bolt, which is hardly accessible, or a stud bolt, which is provided upright on a panel on the lower surface side of the vehicle, into an insertion hole of a stud holt provided on a clamp. For this reason, conventionally, in this type of clamp, the insertion portion of the stud bolt is not formed in a hole shape, and FIG.
As shown in FIG. 2, a slit 101 is provided in the thickness direction of the clamp 100 so as to allow the stud bolt to be easily received in the clamp 100.
In the clamp shown in FIG.
The stud bolt received in the groove 103 communicating with the slit 101 is temporarily fixed by a locking claw piece 102 provided on an edge of the slit 101, and then a nut provided on an upper edge of the groove 103 is provided. Holding piece 104
The nut held in the stud is fitted into the stud bolt with a tool such as an impact wrench, and the clamp is attached to the stud bolt.

[0003]

However, when the insertion portion of the stud bolt is a slit 101, the clamp 100
While the stud bolt can be easily received, the stud bolt thus received is not disposed at the center position of the slit 101, in other words, at a position substantially in the middle of the width dimension of the clamp 100, but does not extend along the longitudinal direction of the clamp 100. A situation may occur in which the components are unevenly distributed on the side edges. In this case, when the nut is fitted into the stud bolt to fix the clamp 100 to the panel, the clamp 10
Reference numeral 0 denotes a displaced position of the stud bolt from a position to be disposed, that is, a position where the clamp 100 would be disposed when the stud bolt is disposed at the center position of the slit 101 of the clamp 100 and fixed to the panel, by the deviation of the stud bolt. Will be assembled to the panel in a state where it is raised. As a result, the arrangement of other members, cords, wires, pipes, and the like, which constitute the vehicle, the arrangement positions of which are determined assuming the planned positions of the clamps 100, is reduced by the biased arrangement of the clamps 100. There were inconveniences, such as being disturbed by 100, making it impossible or difficult to perform. In addition, when the cord, pipe, wire, or the like held by the clamp 100 is pulled for some reason, if the stud bolt is not disposed at the center position of the slit 101, the clamp 100 is pivoted with the stud bolt 101 as a fulcrum. There was a problem that the arrangement position of the clamp 100 was further shifted by being swung. There has been no means for correcting the displacement of the position of the clamp 100 after the fact.

Therefore, the present invention eliminates the inconveniences of the conventional clamp and always places the stud bolt in a predetermined position of the slit irrespective of the receiving position of the stud bolt in the slit provided in the clamp. By providing a clamp having a structure in which the position of the clamp itself with respect to the stud bolt can be adjusted so that the stud bolt is arranged, it is possible to constantly assemble this type of clamp into an easy and proper panel. The purpose is to secure.

[0005]

According to the present invention, in order to solve the inconvenience of the conventional clamp, a wire or rod-shaped clamp is provided in a thickness direction for receiving a stud bolt C standing upright on a panel or the like.
