Abstract
A needle proper is formed to have a hook at the tip, a slider groove formation part, a needle proper center that follows the slider groove formation part, and a rear that allows a control butt to sink into the needle groove. A slider comprises a first slider and a second slider. The first slider is formed by overlapping two thin plates, and tongues are formed on the tips of these plates, and the rear parts of the plates are exposed in the needle proper center, and these exposed portions are coupled with an under arm of the second slider. The second slider is formed to have a head that contacts the upper edge of the slider groove formation part to support the slider, a rear part that allows a control butt, that is protrusively formed on a part extending backward beyond the needle proper center, to sink into the needle groove, and an under arm in the middle for coupling the first slider.
