る。(Prior Art and its Problem) Conventionally, as this type of coupling device, there is one disclosed in JP-A-62-228716. As shown in FIGS. 3 to 7, this connecting device allows the shaft 6 to be inserted into the hole 4 of the boss member 2 and the ball 8 as a connecting member housed in the opening 7 of the boss member 2 to be inserted into the shaft 6. The boss member 2 and the shaft 6 are connected when they are in the setting groove 10. At this time, the leg portion 12b of the set ring 12, which is a ring-shaped member, holds the ball 8 so that the ball 8 does not protrude outward in the radial direction, and is housed in the groove 14 of the set ring 12 on the other hand. The set ring 12 is held at the position shown in FIG. 3 by the spring ring 24 having a substantially looped triangular shape. That is, the spring ring 24 has its three corner portions 51 constrained in the groove 14 of the set ring 12, and at the same time, the three flat portions 50 are respectively on the three inclined planes 28 of the boss member 2. Therefore, the flat portion 50 of the spring ring 24 tries to slide down along the inclined surface 18, but is in contact with the stopper 18 of the boss member, so that the set ring 12 is held at 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
12を第３図で見て左へスプリングリング24の力に抗して

たスプリングリング24の平坦部50は開口７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。Next, in order to separate the shaft 6 from the boss member 2, a set ring
The 12 is moved to the left as viewed in FIG. 3 against the force of the spring ring 24 to reach the position of the set ring 12 in FIG. However, FIG. 6 shows a position where the shaft is to be inserted, and the position of the shaft 6 is the position shown in FIG. When the position shown in FIG. 6 is reached, the ball 8 is in the recess 40 of the set ring 12.
The shaft 6 can be disengaged from the boss member 2 by pulling the shaft 6 to the right as viewed in FIG. Further, the flat portion 50 of the spring ring 24 enters the recess 19a intersecting the opening 7 and holds the set ring 12 in this position.

て滑り落ちるのでセットリング12を第３図のセットリン
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, when inserting the shaft 6 into the boss member 2 next time, it is only necessary to insert the shaft 6. That is, the chamfered portion at the tip of the shaft 6 presses the ball 8 outward in the radial direction. The ball 8 is pushed out of the opening 7, and the flat portion 50 of the spring ring 24 is pressed.
Since the spring ring 24 is removed from the recess 19a (see FIG. 7), the spring ring 24 slides down along the inclined plane 28 due to the force of contraction, so that the set ring 12 is moved to the position of the set ring in FIG. This coupling device is easy to operate and is very effective as this type of coupling device.

る。しかも傾斜面28の傾斜角はスプリングリングとの関
係において或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。こ
のため結合装置の価格が高くなる。However, since the three inclined surfaces 28 of the boss member 2 are processed with a milling cutter, skill is required for the processing and the number of steps is increased. Moreover, the inclination angle of the inclined surface 28 needs to have a certain corresponding angle in relation to the spring ring, and therefore, the accuracy of the inclined surface is required to be high. 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。Further, 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 is adversely affected.

This processing is easy because it can be performed by normal taper processing. The frusto-conical surface 61 allows the inclined plane 28
It is possible to perform an action instead of.
