Claims (4)

[Scope of utility model registration request] (1) A driven shaft with a cylindrical portion formed at one end is pivotally attached to the machine frame,
A shaft end of a driving shaft is rotatably fitted into the cylindrical portion, a locking hole through which a ball can pass through in the radial direction is bored in the cylindrical portion, and the locking hole is formed on the circumferential surface of the drive shaft. A mouth height is provided corresponding to the stop hole, and the depth of the mouth height is set such that the ball that fits therein engages in the locking hole, and for each pair of the mouth height and the locking hole. A shifter ring having a small-diameter inner cylindrical surface that fits into the outer circumferential surface of the cylindrical portion, a tapered inner surface that widens from this, and a large-diameter inner cylindrical surface that continues from the end of the tapered inner surface, into which the ball is fitted, The ball is fitted into the cylindrical part so as to be movable in the axial direction, and when the ball is under the small-diameter inner cylindrical surface of the shifter ring, the ball exists across the corresponding mouth height and the locking hole, and the ball is attached to the shifter ring. A clutch mechanism in which the ball is located within the locking hole and can exist outside the outer peripheral surface of the driving shaft when the ball is located below the surface of the large-diameter inner cylinder. (2) The driven shaft 1 is a stepped shaft, the inner end with a large diameter is formed in the cylindrical part 1a, and the small diameter part of the driven shaft 1 and the inner end of the cylindrical part 1a are arranged side by side in the machine frame 9. 2. A clutch mechanism according to claim 1, which is pivotally mounted on two bearings 10. (3) The large diameter inner cylindrical surface 7 provided inside the shifter ring 8 and the small diameter inner cylindrical surface 5 following the tapered inner surface 6 are fitted onto the outer circumferential surface of the cylindrical portion 1a of the driven shaft so as to be slidable in the axial direction. Clutch mechanism according to claim 1 of the utility model registration claim. (4) Slide grooves 8a are provided in the upper and lower parts of the shifter ring 8, respectively, and the slide grooves 8a are slidably fitted into beds 9a provided in the upper and lower parts of the machine frame 9 parallel to the axial direction of the driven shaft 1. A clutch mechanism according to claim 1 of the utility model registration claim.
