【考案の詳細な説明】
（産業上の利用分野）
本考案はスパナによる締付けを容易にしたねじ
部材に関するものである。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a screw member that can be easily tightened with a spanner.
（従来の技術とその問題点）
ねじ部材は殆どすべての機械、機械部品に広く
使用されており、ねじの締付けにはねじの頭部又
はナツトを六角形に形成しその対向面にスパナを
掛けて締付ける方法が大部分である。(Prior art and its problems) Threaded members are widely used in almost all machines and machine parts. To tighten a screw, the head or nut of the screw is formed into a hexagonal shape, and a wrench is applied to the opposing surface. In most cases, the method of tightening is by hand.
しかし、スパナを１回回す角度は60度程度であ

が邪魔してスパナが掛らないことがある。そこで
スパナの頭部とシヤンクとに角度をつけスパナを
裏返しにすればスパナのシヤンクの角度を変えら

付けるためスパナを僅かしか回転できないことが
ある。 However, since the angle of one turn of the wrench is about 60 degrees, when tightening in a narrow space, the next time you try to apply the wrench to a hexagonal surface, surrounding objects may get in the way and prevent the wrench from engaging. be. Therefore, the head and shank of the wrench are angled so that the angle of the wrench shank can be changed by turning the wrench inside out, but even then, in a narrow space, the wrench may only be able to be turned a small amount due to tightness.
特に機械類は高度化し、複雑化しながら、しか
もコンパクトであることを要求されるので、特に
機械類のメインテナンスには不便を感じることが
多い。 In particular, as machinery has become more sophisticated and complex, and is required to be compact, maintenance of machinery is often inconvenient.
（問題点を解決するための手段）
本考案ねじ部材はこの問題点を解決するためね
じ部材のスパナを掛ける部分をこのねじ部材の軸
線の方向にわたり軸線の周りに一方向に徐々に螺
旋状に捩つたことを特徴とする。(Means for solving the problem) In order to solve this problem, the screw member of the present invention gradually spirals the part of the screw member where the wrench is applied in one direction around the axis of the screw member. It is characterized by being twisted.
本考案はターンバツクルのナツトのようにスパ
ナを掛ける部分が比較的長い部分に有利である。 The present invention is advantageous for parts such as turnbuckle nuts where the part to which the wrench is applied is relatively long.
（作用）
ねじ部材のスパナを掛ける部分を軸線方向にわ
たり徐々に螺旋状に捩つたので、スパナをねじ部
材の軸線方向にずらせばねじ部材に対するスパナ
の角度を任意にとることができるのでねじ部材の
締付け又は取外しが容易となる。(Function) Since the part of the screw member to which the wrench is applied is gradually twisted in a spiral shape along the axial direction, the angle of the wrench with respect to the screw member can be set arbitrarily by shifting the spanner in the axial direction of the screw member. Easy to tighten or remove.
（実施例）
第１図に本考案ねじ部材の一例を示す。このね
じ部材２はねじ部４とスパナを掛ける部分を即ち
頭部６とから成るが、頭部６を六角形にやや長く

に徐々に螺旋状に捩り、螺旋形になるようにす
る。この捩る角度は５〜20度程度である。(Example) FIG. 1 shows an example of the screw member of the present invention. This screw member 2 consists of a threaded portion 4 and a part on which a spanner is applied, that is, a head 6. The head 6 is formed into a slightly elongated hexagonal shape, and the hexagonal surface on which a spanner 8 is applied is formed into a screw as shown in the drawing. The member is gradually twisted in a spiral around the axis in the axial direction of the member to form a helical shape. This twisting angle is about 5 to 20 degrees.
このように構成することによつて、スパナでこ
のねじ部材を回転する時、ねじ部材の軸線方向に
スパナ８をずらせばスパナのシヤンクの角度を任
意にとることができ、容易に締付けを行なうこと
ができる。 With this configuration, when rotating this threaded member with a spanner, by shifting the spanner 8 in the axial direction of the threaded member, the angle of the shank of the spanner can be arbitrarily set, and tightening can be easily performed. Can be done.

る。この場合、ねじ部材１４のめねじは左右半分
を反対ねじにすること勿論である。 FIG. 2 shows an example in which the screw member of the present invention is applied to a nut and used for a turnbuckle. The turnbuckle is a screw member 1 that is screwed into two members 10 and 12.
The screw member 14 is a nut and is relatively long, so it is advantageous to apply the present invention. In this case, it goes without saying that the left and right halves of the female thread of the screw member 14 are oppositely threaded.
（効果）
本考案ねじ部材はスパナを掛ける部分がねじ部
材の軸線方向にわたり徐々にずれて螺旋状になつ
ているため、スパナをねじ部材の軸線方向にずら
せばスパナの角度を任意にとることができ、狭い
場所でもねじ部材の締付け、取外しを容易に行な
うことができる。(Effects) In the screw member of the present invention, the part on which the wrench is applied is gradually shifted in the axial direction of the screw member to form a spiral shape, so by shifting the spanner in the axial direction of the screw member, the angle of the wrench can be set as desired. This makes it possible to easily tighten and remove screw members even in narrow spaces.
