The shaft ends of the two shafts can be connected to each other for transmission by simply tightening the bolts. By this tightening, the connection part till, t
This is because ll+ is pressed against the outer periphery of the shaft end, and the main body (1) and the shaft are connected by frictional force.

直接ねし嵌合させたことである。(Means) A technical means of the present invention for solving the above problem is that a tightening ring that taper-fits into the connecting portion of the main body is directly screw-fitted to the connecting portion.
（作用） 上記技術的手段は次のように作用する。(effect) The above technical means works as follows.

に圧接され、両軸は摩擦力で伝動状態に連結される。The main body is fitted onto the shaft to be connected, and each connecting portion is fitted onto each shaft end. In this state, the tightening ring is fitted over each connection, and when this tightening ring is screwed into the connection, the tightening ring is tightened in the axial direction, and the connection is tightened by the action of the tapered fitting. The inner periphery of the shaft is pressed against the end portion of the shaft to be connected, and both shafts are connected in a transmission state by frictional force.
（効果） 本発明は次の特有の効果を何する。(effect) The present invention has the following unique effects.
締付リングを面接締付けるだけで２軸が連結されるから
、伝＠Ｉ２軸を連結するための作業が簡単である。Since the two shafts are connected by simply tightening the tightening ring face-to-face, the work to connect the two shafts is easy.
軸継手において、従来のよう々締付ポルｉが不要となる
から、その分部品点数か削減でき、安価に製作できる。Since the shaft coupling does not require a tightening hole i as in the conventional case, the number of parts can be reduced accordingly and manufacturing can be done at low cost.

It can be prevented.
（実施例）
以下、本発明の実施例を第１図〜第４図に基ついて説明
する。(Example) Examples of the present invention will be described below with reference to FIGS. 1 to 4.

A slit 03) is provided in the connecting part [+1), fll) provided at both ends of the slit 03), and the outer periphery thereof is made into a tapered surface (121).
Furthermore, a threaded cylinder 114) is formed following this connection part, and on the other hand, the tightening rings +21 and 12) have the same taper inner circumference as the tapered surface 0, and the small diameter side thereof. This is a parallel hole, and a certain range on the tip side of this parallel hole is the threaded cylinder (threaded part area that is screwed into 141).

すなわち、締付可能となる。In other words, it becomes possible to tighten.
次に、第３図に示す第２実施例のものは、主体（１）の

この実施例ではフック継手構造を採用しである。Next, in the second embodiment shown in FIG. 3, the central part of the main body (1) can be bent in all directions.
This embodiment employs a hook joint structure.

When the tightening rings (2+, +21) are screwed in with the shafts (D), , (D)K fitted on the outside of the shafts (D), (D), the connection parts fi11 and +11 are screwed in due to the action of the mutual taper threads.

このものでは、テーパー嵌合部がその１寸ネジ嵌合部と
なっているから、第１実施例のように別個にネジ嵌合部
を用意する必要がなく、全体が小型化できる。In this case, since the tapered fitting portion is a one-inch screw fitting portion, there is no need to prepare a separate screw fitting portion as in the first embodiment, and the overall size can be reduced.
また、主体（１）の中央部は全方向に屈曲自在となって

を利用できることは言う捷でもない。In addition, since the central part of the main body (1) is bendable in all directions, it can be used even when the two axes (DJ, (DJ) to be connected intersect. There is no lash.It goes without saying that other known universal joints can be used in addition to the hook joint.
尚、第２実施例の接続部（１１）と締付リング（２）と
の関係ばそのまま第１実施例にも採用可能であシ、又、
逆の関係についても同様である。Incidentally, the relationship between the connecting portion (11) and the tightening ring (2) in the second embodiment can be adopted as is in the first embodiment, and
The same applies to the reverse relationship.
上記第２実施例において、テーパーネジは１／１０〜１
／１６のテーパーとし、ネジ山の角度は通常のネジにく

ている。In the second embodiment above, the taper screw is 1/10 to 1
It has a taper of /16, and the angle of the thread is set larger than that of a normal screw, for example about 90 degrees.
このことから、締付リング＋２１ 、 ＋２１を締付け
た場合、通常のネジにくらべて半径方向の作用力の割合
が大きくなり、締付リングの締付けによる接続部の圧接
力が向上する。言い換えれば、締付トルクが軸圧振力に
効果的に変換されることきなる。Therefore, when the tightening rings +21 and +21 are tightened, the ratio of the acting force in the radial direction becomes larger than that of a normal screw, and the pressure contact force of the connection portion due to tightening of the tightening rings is improved. In other words, the tightening torque is effectively converted into axial pressure vibration force.

Alternatively, as shown in FIG. 4, it is constructed in the form of a screw thread or a series of circular arcs. This also applies to the case of so-called round screws; rather, these types of screws improve the pressure contact force conversion effect and improve the shaft connection strength.
