The female thread part 9' of the nut cylinder 8 is screwed into the male thread part 4, and the nut cylinder 8 is fitted onto the U-shaped rod 2.
is slid to the other part of the U-shaped rod 2 to lock the locking part 7 and the locking collar part 9. Next, the male threaded part 4 is screwed into the joint female threaded cylinder 3, and the tip of the joint female threaded cylinder 3 is clamped, for example, with an appropriate tool, so that the male threaded part 4 is removed from the joint female threaded cylinder 3. Set it up so that it does not fall off. By rotating the U-shaped rod 2 with respect to the U-shaped rod 1, or by rotating the U-shaped rod 1 with respect to the U-shaped rod 2, it is formed by the tip of the male thread part 6 and the tip of the nut tube 8. When the wire rope 10 is introduced into the product of the present invention through the opening, and the female thread 8' and the male thread 6 of the nut tube 8 are screwed together, the product and the wire rope 10 are connected. The rotation of the U-shaped rod 2 with respect to the U-shaped rod 1 or the rotation of the U-shaped rod 1 with respect to the U-shaped rod 2 is caused by interposition between the bottom of the joint female screw tube 3 and the tip of the male screw portion 4. This is suppressed by the elastic body 5 (excessive rotation is suppressed), and wobbling between the U-shaped rods 1 and 2 is also suppressed.

部９により形成される開口１３の径も自ら定まる
ことになる。開口１３の径が定まると、ナツト筒
８が螺入される雄螺子部４の径も定まる。 A locking flange 9 is provided at the base end of the nut tube 8 to enable engagement between the nut tube 8 and the locking portion 7, but the degree of inward protrusion of this locking flange 9 is determined by It is determined by the degree of outward bulge of the stop portion 7. This locking flange 9
The fact that the degree of inward protrusion is determined means that the diameter of the opening 13 formed by the locking collar 9 is also determined by itself. When the diameter of the opening 13 is determined, the diameter of the male threaded portion 4 into which the nut cylinder 8 is screwed is also determined.
そこで、発明者は雄螺子部４の径を少しでも大
きくする為の方策を発明した。 Therefore, the inventor devised a method for increasing the diameter of the male screw portion 4 as much as possible.
即ち、係止鍔部９の内面に雌螺子部９′を形成
することである。雌螺子部９′を形成することで
雄螺子部４の径は、雌螺子部９′を形成しない場
合（第５図の左側）に比し、２×l2だけ径大とな
る（第５図参照）。 That is, a female screw portion 9' is formed on the inner surface of the locking collar portion 9. By forming the female threaded portion 9', the diameter of the male threaded portion 4 becomes larger by 2×l 2 (the fifth (see figure).

The drawing shows an embodiment of the present invention, with a male screw part 6 at one end,
One U-shaped rod 1 is formed by bending a rod having a joint female screw tube 3 integrally connected to the other end.

方のＵ状杆２を形成する。 Next, a male screw portion 4 having a diameter that can be screwed into and passed through the opening 13 formed by the locking collar portion 9 is attached to the nut tube 8 at the other end.
A rod is provided with a locking part 7 that prevents the nut cylinder 8 from coming off with a locking collar part 9, and the nut cylinder 8 is
A female screw portion 9' formed in the opening 13 of the locking flange 9 of
is screwed into the male screw part 4, and the nut cylinder 8 is attached to the U-shaped rod 2 as shown in FIG. 4, and then the rod is bent to form the other U-shaped rod 2.

する。 A recess 11 into which a coiled spring is inserted is provided at the end of the male thread 4 of the U-shaped rod 2, the spring is inserted into the recess 11, and the male thread 4 is screwed into the joint female thread cylinder 3. The open end 3' of the inserted successor female threaded tube 3 is caulked to prevent the male threaded portion 4 from coming out of the female screwed tube 3.
この場合最先端のねじ山を壊さないよう座金１
２を装着することが望ましい。 In this case, use washer 1 to avoid damaging the leading edge thread.
It is desirable to install 2.

止される。 The spring action of the spring prevents the male threaded portion 4 from rattling against the joint female threaded tube 3, and the U-shaped rod 1
Since the rotation of the U-shaped rod 2 is suppressed, the threaded connection between the male screw part 6 and the nut tube 8 is released, and the wire rope 1 is
When the U-shaped rod 2 is rotated with respect to the U-shaped rod 1 in order to connect the U-shaped rod 2 with this product, the U-shaped rod 2 rotates too much (the U-shaped rod 2 rotates more than necessary). ) is prevented.
尚、クツシヨン材はゴムやスポンジなどの柔軟
材を使用する。 The cushion material is made of a flexible material such as rubber or sponge.
