A device that can control the suction force. The casing and the magnet are detented or glued to prevent slippage. By fixing the outer periphery of the magnet, it is possible to cope with the eccentricity of the shaft, but it is difficult to cope with the eccentricity of the shaft. The precision of the shaft fixture was maintained by a hard aluminum alloy or the like. In addition, the detents protrude on the fixture side in accordance with the recesses of the magnet.

In the manual operation, the handle bar (8) is used, but in the case of a tapping machine, the upper end of the upper case is chucked. The upper case rotates together with the magnet A, but when overloaded, the magnet B slips so that the tap does not break.
FIG. 5 shows a thrust moving clutch rotation transmitting mechanism. When the right end stopper of the shaft is removed, the N of the magnet A is attracted to the S of the magnet B, the shaft fixed (1) with the clutch plate is moved to the right, The rotation is transmitted to the upper case (5). When receiving the overload torque, the left axis moves to the left and the rotation transmission stops.
