There is a device such as that disclosed in Japanese Patent Application No. 30524 (Japanese Patent Application No. 53-102361), which consists of a motion coupling member attached to the outer periphery of the shaft end of the rotary drive member, and a motion coupling tube attached to the outer periphery of the shaft end of the driven member. A tapered thrust sleeve for torque transmission and interruption inserted and disposed between the engagement groove and the engagement groove having a circular cross section provided on the outer periphery of the interlocking connection portion. A steel ball for torque transmission is played in each engagement recess provided on the inner circumferential surface of the corresponding motion coupling cylinder, and a narrower steel ball is played in the back vertical surface of the tapered thrust sleeve and on the outer periphery of the tapered thrust sleeve. - Since the tapered thrust sleeve is supported by each contact point with a small steel ball interposed between the upwardly inclined surface of the thrust ring and the inner sloped surface of the motion coupling cylinder, the support of the tapered thrust sleeve is a point contact support; It is structurally unstable, and has the disadvantage that the tapered thrust sleeve tends to bend under the influence of centrifugal force during high-speed rotation, resulting in inaccurate rotation.

達が行われるようになる。At that time, the thrust small steel ball 19 is pressed between the inclined surface 15' and the vertical front surface 18'' of the Taber thrust ring 18 by the inner flat surface 18'' of the tapered thrust sleeve 12, and the sixth The state shown in the figure is maintained. Therefore, in this state, the repulsion force of the elastic spring 8 causes the Taber thrust ring 1 to
8 could not return to its original state, that is, the state shown in Figure 3,
The rotation drive unit 1 and the driven member 4 are disengaged, and the rotation of the rotation drive member 1 is not transmitted to the driven member 4.
In addition, when the cause of overload is removed and the rotational drive member 1 and the driven member 4 are reset, the torque transmission steel ball 7
After rotating and aligning the interlocking connecting tube 9 so that the lower surface of the interlocking connecting body 2 matches the engagement groove 3 of the interlocking connecting body 2, the tapered thrust sleeve 12 is moved to the left side in FIG. In other words, when pressed to the position shown by the dotted silver line in the same figure, the torque transmitting steel ball 7 receives a downward pressing force from the downwardly facing inclined surface 13 of the tapered thrust sleeve 12, and the engagement recess of the movement coupling body 2 is pressed. Since its lower surface is fitted into the groove 3, the Taber thrust sleeve 1
2 moves to the left, and in order to release the pressing force against the thrust small steel ball 19 by the inner flat surface 18''', this movement causes the thrust 4 and the steel ball 19 to return to their original state due to the restoring force of the elastic spring 8. In other words, as shown in FIG. The rotary drive unit 1 and the driven member 4 are connected and rotate together, so that the required power is transmitted.

ができる等の特長がある。As described above, the present invention transmits the required power during normal loads and cuts off the power transmission during overloads. Since the tube and the inner hem edge of the moving connecting tube are formed as one piece, the structure is stable and the interlocking connecting tube does not wobble during high speed rotation.
It is possible to perform accurate rotation and reliably transmit torque, and when connecting the rotary drive member and the sliding member, some relative displacement between the respective members in the vertical direction, that is, a gap error between the ends of the ball, is as described above. Easily absorbed by moving each member apart and toward each other in the direction of gravity using the engagement groove formed on the outer peripheral surface of the interlocking connection body and the rolling of the torque transmission steel ball that meets the groove. In addition, minute relative radial displacements between the above-mentioned members, that is, vertical and horizontal deviations between the shaft ends, are caused by the difference between the inner circumferential surface of the bottom edge of the motion coupling tube and the outer circumferential surface of the tapered thrust sleeve. It has the advantage of being able to be easily absorbed by utilizing the gaps between them.
