のでしる。Detailed Description of the Invention (Field of Industrial Application) The present invention comprises a boss member and a shaft that fits into a hole in the boss member. The shaft can be removed from the boss member with one hand by simply moving the member in the axial direction, and the shaft can be connected to the boss member by simply inserting the shaft into the hole in the boss member. This article concerns a flexible coupling device.

４図に示す位置にセラ） ＩＪソング２は保持される。(Prior art and its problems) Conventionally, this type of coupling device was disclosed in Japanese Patent Application Laid-open No. 62-22871.
There is something disclosed in No. 6. This coupling device is the 4th to 8th
As shown in the figure, the shaft 6 can be inserted into the hole 4 of the boss member 2, and the ball 8 as a coupling member housed in the open lower part of the boss member 2 is inserted into the set groove IO of the shaft 6. At this time, the boss member 2 and the shaft 6 are connected. At this time, the leg portion 12 of the set ring 12 is a ring-shaped sliding member to prevent the ball 8 from flying outward in the radial direction.
b holds down the ball 8, while a loop-shaped, substantially triangular spring ring 24 housed in the groove 14 of the set ring 12 holds the set ring 12 in the position shown in FIG. That is, the spring ring 24 has its three corner portions 51 restrained within the groove 14 of the set ring 12, and at the same time, its three flat portions 50 are located on the three inclined planes 28 of the boss member 2, respectively. Therefore, the flat part 50 of the spring ring 24 tries to slide down along the inclined surface 18, but since it comes into contact with the stopper I8 of the boss member, the IJ song 2 is held in the position shown in FIG.
次に軸６をボス部材２から離脱させるにはセットリング

７図の位置に達すると、ボール８はセットリング１２の
凹所４０内に入ることができるから、軸６を第４図で見
て右へ引くと軸６をボス部材２から離脱させることがで
きる。Next, in order to separate the shaft 6 from the boss member 2, the set ring 12 is moved to the left in FIG. 4 against the force of the spring ring 24 until it reaches the position of the set ring 12 in FIG. However, FIG. 7 shows the position where the shaft will be inserted from now on, and the position of the shaft 6 is the position shown in FIG. 4. When the ball 8 reaches the position shown in FIG. 7, it can enter the recess 40 of the set ring 12, so that when the shaft 6 is pulled to the right as seen in FIG. 4, the shaft 6 can be separated from the boss member 2. Can be done.
またスプリングリング２４の平坦部５０は開ロアに交差
する凹所１９ａに入り、この位置にセットリング１２を
保持する。Further, the flat portion 50 of the spring ring 24 enters the recess 19a intersecting the open lower portion, and holds the set ring 12 in this position.

のセットリングの位置に移動させる。この結合装置は操
作が簡単でこの種の結合装置として非常に有効である。Therefore, the next time the shaft 6 is inserted into the boss member 2, it is sufficient to simply insert the shaft 6. That is, the chamfered portion at the tip of the shaft 6 presses the ball 8 radially outward. While the ball 8 is pushed out from the open lower part, the flat part 50 of the spring ring 24 does not come out of the recess 19a (see Figure 8), and the spring ring 24 slides down along the inclined plane 28 due to the force of contraction, so that it is not set. The ring 12 is moved to the set ring position shown in FIG. This coupling device is easy to operate and is very effective as a coupling device of this type.
しかし、ボス部材２の３個の傾斜面２８の加工をフライ
スで行っているためその加工に熟練を要し、工数が多く
なる。しかも傾斜面２８の傾斜角はスプリングリングと
の関係において成る対応する角度を有することが必要で
あり、このため傾斜面の精度が高いことが要求される。However, since the three inclined surfaces 28 of the boss member 2 are processed using a milling cutter, the processing requires skill and increases the number of man-hours. Moreover, the angle of inclination of the inclined surface 28 needs to have a corresponding angle in relation to the spring ring, which requires that the inclined surface has high precision.
このため結合装置の価格が高くなる。This increases the cost of the coupling device.
またスプリングリング２４と傾斜面２８との相対加工精
度が悪い場合にはボス部材と軸との結合に悪影響がある
。Furthermore, if the relative machining accuracy between the spring ring 24 and the inclined surface 28 is poor, the connection between the boss member and the shaft will be adversely affected.

を特徴とする。(Means for solving the problem) In order to solve this problem, the coupling device of the present invention includes a boss member,
a shaft that can fit into the hole of the boss member; a coupling member that is accommodated in the opening of the boss member and engages with a groove around the shaft to prevent the shaft from slipping out of the boss; and the coupling member a sliding member movable between a first position for retaining the coupling member in a groove around the shaft and a second position for allowing the coupling member to move away from the groove around the shaft; and a loop-shaped spring that moves the sliding member to either the first position or the second position by a force that contracts along an inclined surface around the boss member. The boss member is characterized in that the inclined surface is formed as a single truncated conical surface, the loop-shaped spring is provided with a protrusion, and the protrusion is fitted into a groove formed in the axial direction of the boss member.

リングリングと截頭円錐面との相対加工精度がボス部材
と軸との結合に悪い影響を与えない。(Function) Instead of forming multiple Taper surfaces on the circumference, we adopted a truncated conical surface, making processing extremely easy. Furthermore, the relative machining precision between the spring ring and the truncated conical surface does not adversely affect the connection between the boss member and the shaft.
溝と突起との嵌合によってばねの回転を確実に防止する
ことができる。The rotation of the spring can be reliably prevented by the engagement between the groove and the protrusion.

傾斜平面２８に代わる作用を行わせることができる。(Embodiment) In the present invention, a truncated conical surface 61 is formed in place of the three inclined planes 28 of the boss member 2 on which the flat portion 50 of the spring ring 24 moves. This processing is easy as it can be done by normal taper processing. This frusto-conical surface 61 can perform an action in place of the inclined plane 28.
しかし、スプリングリング２４は傾斜平面２８の場合と
異なり軸線の回りに回転できるようになるから、スプリ
ングリング２４の回転を防止する必要がある。However, since the spring ring 24 is able to rotate about the axis unlike the case of the inclined plane 28, it is necessary to prevent the spring ring 24 from rotating.

。In the present invention, an axial groove 62 is formed in the boss member 2, and a protrusion 63 is formed in the spring ring 24. Groove 6
2 prevents the spring ring 24 from rotating. In this embodiment, the protrusion 63 is brazed to the spring ring 24, but other means may be used. FIG. 3 shows an example of two types of protrusions 630.

Furthermore, since the fitting between the groove and the protrusion was used to prevent rotation, it was possible to reliably prevent the spring ring from rotating.
