の位置にもどる。In this operation, when the coil 5 is energized and excited, the plunger 6 is pulled toward the base 2 to perform a suction operation. At this time, the shaft 7 slides in the bearing 3 together with the plunger 6. Return operation is coil 5
When the deenergization is stopped by stopping the energization to, the spring returns to the original position by the force of the return spring 9.

の場合は電池寿命が短くなる。 (2)When it is desired to keep the plunger 6 in the attracted state, the coil 5 must be continuously energized. For this reason, the coil heats up, the adsorbing force also weakens accordingly, and the battery life is shortened when the battery is driven. (2)

Install 2. The intermediate magnetic pole 13 is the base 2 of the permanent magnet 12.
And press it into case 1 to fix it. The base 2 is press-fitted and fixed to the holder 11, and the holder 11 is press-fitted and fixed to the intermediate magnetic pole 13.

レノイドの小型化が可能となる。 (3)Many types of open-frame type self-holding solenoids are known, but the polarities of the permanent magnets are arranged in the direction outward from the center of the solenoid. Therefore, there is a drawback that the solenoid itself becomes large. In the structure of the present invention, the permanent magnet can be formed into a donut shape so as to be inserted into the base of the magnetic body, and the solenoid can be miniaturized. (3)

態を保つことができる。[Explanation of effect] Since it is attracted by pulse input and attracted and held by the permanent magnet, holding power is not required and coil heat is not generated during holding. Therefore, the energy saving effect can be achieved and the solenoid can be downsized. Further, the holding state can be maintained without any influence even during a power failure in the adsorption state.
