非吸着状態とする。 Then, by rotating the knob 3, the rotating magnet 1 moves from one magnetic pole 2B to the magnetic material (not shown).
→A magnetic flux path is formed that returns to the other magnetic pole 2B and the rotary magnet 1, and the magnetic base is attracted to a magnetic material such as a machine tool body. Further, by reversing the knob 3, the magnetic flux path is opened and the magnetic base is placed in a non-adsorbed state.
（考案が解決しようとする問題点）
この磁気ベースにおいてつまみ３に注目する

A notch must be provided so that the stopper 4 can escape. Therefore, the shape of the mold for molding the knob 3 becomes complicated.
（問題点を解決するための手段）
上記問題点を解決するため、本考案では、回動
磁石の段部はストツパの当接用に利用し、つまみ

いるストツパに当接する。(Function) With this configuration, the rotary magnet is rotated by being given rotational force by the knob attached to one end, and when it rotates to a certain extent, the step provided at the other end of the rotary magnet is rotated. part comes into contact with a stopper attached to the magnetic block.
（実施例）
第１図ないし第３図は本考案の実施例を示した
ものである。(Embodiment) FIGS. 1 to 3 show an embodiment of the present invention.
第１図は本考案の一実施例を示したもので、回
動磁石１の一方の端部にある段部１Ｃはストツパ

の都合上、つまみ３を裏側から見た状態としてい
る。 FIG. 1 shows an embodiment of the present invention, in which a stepped portion 1C at one end of the rotating magnet 1 is used only for abutting the stopper 4, and a flat portion at the other end. Knob 3 is attached to 1B. For convenience of illustration, the knob 3 is shown as seen from the back side.
この場合、段部１Ｃに対するストツパ４の当接
の仕方は第４図の従来例と同様であるが、平坦部
１Ｂに対するつまみ３の係合の仕方は従来と異な

要なものである。 In this case, the manner in which the stopper 4 abuts against the stepped portion 1C is similar to the conventional example shown in FIG. 4, but the manner in which the knob 3 engages with the flat portion 1B is different from the conventional example. In other words, the rotary magnet 1 has a flat portion 1A formed during the machining process, and the knob 3 engages with the rotary magnet 1 using this flat portion 1A. The knob 3 is fixed to the rotary magnet 1 by, for example, adhesive. Note that the flat portion 1A is necessary in order to reduce the defective rate when cylindrical magnets are magnetically press-molded in the diametrical direction.
このように平坦部１Ｂにつまみ３を取付けるた

ことにより連設する。 FIGS. 2 and 3 show a configuration in which a plurality of rotary magnets 1 are arranged in series in the axial direction. FIG. 2 shows the convex portion 1 provided on the end face of each rotating magnet 1.
C and the concave portion 1D are combined, and as shown in FIG. 3, the intervening member 5 is inserted using the convex portion 1C on the end face of each rotating magnet 1 and bonded as necessary. .
このような構成により磁石をつなげる場合にも
その凸部が利用でき、吸着力の強力な磁気吸着装
