（従来技術）
従来のソレノイドとしては、一般に第４図に示すような
ものがある。(Prior Art) As a conventional solenoid, there is generally one shown in FIG.
この従来のソレノイドは、固定鉄心（１）にコイル（２
）が取付けてあり、その中に可動鉄心（３）が挿通され
ていて、コイル（２）に通電すると、可動鉄心（３）が
吸引されるようになっているものである。This conventional solenoid has a fixed core (1) and a coil (2
), a movable iron core (3) is inserted through it, and when the coil (2) is energized, the movable iron core (3) is attracted.
（従来技術の問題点）
以上のような従来のソレノイドは、一方向にのみ作動す
るものであるため、使用目的によって双方向への作動が
要求される場合には、この種のソレノイドを２箇組合せ
て使用していたが、２箇組合せた場合は構造、機構が複
雑になるという問題があった。(Problems with the prior art) The conventional solenoids as described above operate only in one direction, so if the purpose of use requires bidirectional operation, two solenoids of this type are required. Although they were used in combination, there was a problem in that the structure and mechanism became complicated when the two were combined.
（本発明の目的）
本発明の目的は、以上のような従来ソレノイドの問題点
を解決し、１つのソレノイドで双方向への作動を可能と
することにある。(Objective of the present invention) An object of the present invention is to solve the problems of conventional solenoids as described above, and to enable bidirectional operation with one solenoid.
（本発明の構成）
この目的を達成するため、本発明双方向のソレノイドは
、コイルを外装した筒状コアと、この筒状コアより長い
、該筒状コアに摺動自在に挿通された非磁性体からなる
可動棒と、前記筒状コアの両側にあって同じ極が対向す
るように所定間隔を隔てて前記可動棒に固定された一対
の磁石とを具備した構成とした。(Structure of the present invention) In order to achieve this object, the bidirectional solenoid of the present invention includes a cylindrical core that is covered with a coil, and a non-wire that is longer than the cylindrical core and is slidably inserted into the cylindrical core. The present invention includes a movable rod made of a magnetic material, and a pair of magnets fixed to the movable rod at a predetermined interval on both sides of the cylindrical core so that the same poles face each other.
（本発明の作用効果）
本発明双方向ソレノイドは上記の構成としたので次の作
用効果を奏する。(Actions and Effects of the Present Invention) Since the bidirectional solenoid of the present invention has the above-described configuration, it exhibits the following effects.
（ｉ）コイルに電流を通じると、筒状コアの端部にＳ極
Ｎ極が生じ、可動棒に固定した磁石は、同じ極（例えば
Ｎ極とＮ極）を対向せしめているので筒状コアの一端に
おいては異極（例えばコアのＳ極と磁石のＮ極）となっ
て引き合うと同時に他端においては同極（例えばコアの
Ｎ極と磁石のＮ極）となって反発し合うため、可動棒は
一方に移動する。(i) When a current is passed through the coil, S and N poles are generated at the ends of the cylindrical core, and the magnet fixed to the movable rod has the same poles (for example, N and N poles) facing each other, so the cylindrical shape At one end of the core, they have different poles (for example, the S pole of the core and the N pole of the magnet) and attract each other, while at the other end they have the same poles (for example, the N pole of the core and the N pole of the magnet) and repel each other. , the movable rod moves to one side.
マタ、コイルに電流を逆に流すと（コイルの巻き方向を
逆としても同様）、先と逆の極が筒状コアの端部に生ず
るので可動棒は先と逆方向に移動する。Actually, when current is passed through the coil in the opposite direction (the same applies even if the winding direction of the coil is reversed), the opposite pole is generated at the end of the cylindrical core, so the movable rod moves in the opposite direction.
すなわち、本発明双方向ツルノイドによれば、双方向へ
の全く同様な動作が得られる。That is, according to the bidirectional tournoid of the present invention, exactly the same operation in both directions can be obtained.
（ｉｉ ）可動棒は非磁性体で構成したので可動棒が筒
状コアの磁力の影響を受けず、したがって極めてスムー
ズな動作が得られる。(ii) Since the movable rod is made of a non-magnetic material, the movable rod is not affected by the magnetic force of the cylindrical core, and therefore extremely smooth operation can be achieved.
（ｉｉｉ ）可動棒には磁石を固定しているので可動棒
が移動した後、コイルへの通電を解除しても磁石が筒状
コアに吸着されて、可動棒の自己保持がなされる。(iii) Since the magnet is fixed to the movable rod, the magnet is attracted to the cylindrical core and the movable rod is self-retained even if the coil is no longer energized after the movable rod has moved.
（ｉｖ ）従来、双方向への作動が要求される場合は、
ソレノイドを２箇組合せる必要があったが、本発明によ
れば一つのソレノイドで足り、したがって構造、機構の
簡易化を図ることができ、経済的にもコストの低減を図
ることができ°る。(iv) Conventionally, when bidirectional operation is required,
It was necessary to combine two solenoids, but according to the present invention, one solenoid is sufficient, and therefore the structure and mechanism can be simplified, and costs can be reduced economically. .

（１３）は、可動棒であって、非磁性体からなり、筒状
コア（１０）に挿通されている。可動棒（１３）は例え
ば銅製とする。(13) is a movable rod made of a non-magnetic material and inserted into the cylindrical core (10). The movable rod (13) is made of copper, for example.
（１４） （１５）は、一対の磁石であり、筒状コア
（１０）の両側にあって同じ極が対向するように所定間

例では、磁石（１４） （１５）として、リング状の
永久磁石を使用し、Ｎ極同志を対向せしめて可動棒（１
３）に固定しである。(14) A pair of magnets (15) are fixed to the movable rod (13) at a predetermined interval on both sides of the cylindrical core (10) so that the same poles face each other. In this embodiment, ring-shaped permanent magnets are used as the magnets (14) and (15), with the N poles facing each other and the movable rod (1
3) is fixed.
なお、（１６）は、ケースを示す。Note that (16) indicates a case.
次に第２．３図を参照して作用を説明する。Next, the operation will be explained with reference to FIG. 2.3.
先ず第２図に示すように、コイル（１１）に電流を通電
すると、筒状コア（１ｏ）の右端がＳ極、左端がＮ極と

にあった可動棒（１３）（第３図参照）は矢印（ａ）で
示すように磁石（１５）が筒状コア（１ｏ）に吸着され
るまで左動する。First, as shown in Fig. 2, when current is applied to the coil (11), the right end of the cylindrical core (1o) becomes the S pole and the left end becomes the N pole, and the right end attracts the magnet (15) and at the same time At the left end, the magnet (14) is repelled, so the movable rod (13), which was initially on the right (see Figure 3), attracts the magnet (15) to the cylindrical core (1o) as shown by the arrow (a). Move to the left until
この後、通電を解除しても磁石（１５）が筒状コア（ｌ
Ｏ）の右端に吸着されているので可動棒は第２図示の位

れる。After this, even if the electricity is turned off, the magnet (15) remains in the cylindrical core (l).
Since the movable rod is attracted to the right end of O), the movable rod is held at the position shown in the second figure. Therefore, even if the current flowing through the coil (11) is a pulse signal, self-maintenance is achieved.

11) When a current is applied in the opposite direction to that in Figure 2,
The left end of the cylindrical core (10) is the S pole, the right end is the N pole,
At the left end, the magnet (15) is repelled, so the movable rod (
13) moves to the right as shown by arrow (b) until the magnet (14) is attracted to the cylindrical core (10).
