であつた。 Conventionally, as shown in FIG. 1, hook parts 2, 2 are provided at both ends of a side spring 1.
2 over the cover 3 and base 4 and engage them, or
Further, as shown in Fig. 2, a hook portion 2' is provided at one end, and a seat portion 5 is provided at the other end tightly wound with at least two turns in a concentric circle slightly larger than the diameter φ ₁ of the side spring 1'. This seat portion 5 is a hole 3 provided in the cover 3.
The hook part 2' at one end was engaged with the base 4 to set it. However, in the former case (Fig. When it falls down, the hook part 2 on the other end
It was necessary to engage the base 4 while searching for it with a jig, which made the work extremely troublesome and difficult to automate. In addition, regarding the latter embodiment (Fig. 2), the seat 5 must be aligned with the core of the side spring 1', and the seat 5 must be wound with at least two turns so that when it is pulled, Hole 3a
In addition, depending on the tension of the side spring 1', the seat part 5 may rotate, so the seat part 5 may bite into the hole 3a, and the effective number of windings will change, and the tension will change, and the platform balance will change each time. It was inconvenient to have to adjust the zero point adjustment knob (not shown) provided on the

本考案は上記欠点に鑑み、座部５の巻数は少な

小さい間隔とする。 Figure 3 shows the side spring 10 in this invention.
FIG. This side spring 10 is
A conventional inverted round hook part 11 is provided vertically at one end,
The other end forms a seat part 12 in a direction H perpendicular to the acting direction V of the side spring 10, and the shape of this seat part 12 when viewed from above is as shown in FIGS. 3 and 4.
It has a polygonal shape as shown in the figure or an elliptical shape as shown in FIG. At this time, the width h between the hook 11, the tips 11a and 12a of the seat portion 12, and the winding end ends 10a and 10a of the side spring 10,
h is a distance smaller than the wire diameter φ ₂ of the side spring 10.

A hole 15 is provided in the middle part, and on both sides of this hole 15,
The protruding convex portions 16, 16 are provided by molding.

１７はベースである。このベース１７内には図

The side spring 10 is pressed in by hooking the base 11' of the hook part 11 onto the inverted U-shaped engaging part 19a at the tip of the jig 19, which is in contact with a, a between the convex parts 16 and 16. The engaging piece 18 slides on the R-shaped head 18a of the engaging piece 18 while being pulled.
The base 17 and the cover 13 are stretched together. After that, remove the jig.

有効巻数が変化することはなく、常に定位置に
位置している。 In this way, compared to conventional products, 1. One hook part of the side spring is made into a polygonal or elliptical shape, and the cover 13 is provided with a recessed part 14 that matches this shape, so that the side spring 10 can be pulled strongly. Even if the side spring 10 is jammed, the recessed portion 14 and the convex portions 16 act as a stopper, and the side spring 10 itself does not rotate, so that it does not get caught in the hole 15.
The effective number of turns does not change and always remains in a fixed position.

２座部１２の処理ターン数が多くても１ターン
で処理できるため、処理が行いやすい。2. Even if the number of processing turns of the seat portion 12 is large, it can be processed in one turn, so processing is easy.

The tips 2 of the hooks 2 and 2'
Width between a, 2a' and end of winding 1a, 1a
h' and h' had to be made wider, which caused them to become entangled with each other during production, making handling troublesome; however, in the case of the present invention, the widths h' and h' are made larger than the wire diameter _φ2 of the side spring 10. Because they are small, they do not get entangled with each other and are easy to handle.
