が必要な場合がある。Ordinary screws have a plus or minus groove in their head so that they can be tightened and removed using a plus or minus dry no. Since the above-mentioned dry nozzle is a familiar item, it is possible to sharpen the screw even if it is bent, but in order to prevent the disassembly of a familiar device that poses a danger to general users, it can be attached and detached without using a special screwdriver. In some cases, screws that cannot be used may be required.

イナスの溝を螺頌頂面に設けないものがあるが楕円形の
ため製造コストが高くつき且ペンチ等で脱される欠点を
有している。Some special screws have an oval head shape and do not have positive or negative grooves on the top surface of the screw, but because of the oval shape, the manufacturing cost is high and it has the disadvantage that it can be removed with pliers etc. There is.
本発明は上記した欠点を除いた特殊螺子に関し、以下実
施例について説明する。The present invention relates to a special screw that eliminates the above-mentioned drawbacks, and examples thereof will be described below.
（１）は螺子山（２）を有する螺子杆部（３）と円形４
頭部（４）からなる螺子、（５）は前記螺頭部（４）須

線上と交叉するようになっていて、且前記交叉する部分
のみが他の部分より拡巾しである。(1) is a threaded rod (3) with a threaded thread (2) and a circular 4
A screw consisting of a head (4), (5) is a curved groove provided on the face of the screw head (4), which has the same width and a part thereof intersects with the center line of the screw rod. In addition, only the intersecting portion is wider than the other portions.
前記ｌ状溝の一例として図示したようにＳ字状又は逆Ｓ
字状が適する０本発明は上記した構造であるから、通常
のプラス、マイナスドライバーでは曲状溝に嵌合できず
又螺頭の形状が円形であるからペンチ等によっても着脱

応じて拡巾しておけばドライバーが正しい位−に整合さ
れるので着脱時に適切に力が螺子Ｉｒ−加えられる。As shown in the figure as an example of the L-shaped groove, an S-shaped groove or an inverted S-shaped groove is formed.
Since the present invention has the above-mentioned structure, it cannot be fitted into the curved groove with a normal Phillips or flathead screwdriver, and since the shape of the screw head is circular, it cannot be attached or detached with pliers or the like. Only the center part of the curved groove is wider than the other groove widths, so if you widen only the center part of the tip of the screwdriver according to the groove width, the driver will be aligned at the correct position, making it easy to install and remove. When appropriate, force is applied to the screw Ir-.
