使用を制限される等の問題があった。(Problems to be Solved by the Invention) In the above-mentioned conventional electromagnetic drive device, first of all, the driving force is not very large due to the TL magnetic non-lenoid structure, and in order to increase the driving force, it is necessary to increase the current value flowing through the coil. Therefore, power consumption will inevitably increase.On the other hand, a combination of an electromagnet and a movable piece of iron can provide a large amount of WIA power, but on the other hand, the magnetic force that acts is inversely proportional to the square of the distance between the electromagnet and the moving piece of iron. There were problems such as short driving distance and limited use.

Permanent magnets that are movable and strongly repel each other due to the magnetic force of the same polarity (3)
In this case, 1 is rapidly separated from the magnet (2) and moved. Correspondingly, the operating shaft (4) fixed to the permanent magnet (3) is also moved, and this operating shaft (4) operates other devices. Also, if a spring (5) is elastically provided between the electromagnet (2) and the permanent magnet (3) as shown in Figure 1,
The permanent magnet (3) is repelled by the combination of magnetic force and elastic force of the spring (5). In other words, the magnetic force of the TrL magnet (2),
The permanent magnet (3) is strongly driven by three forces: the magnetic force of the permanent magnet (3) and the elastic force of the spring (5). When the spring is provided in this way, the Tr
Even if the current to the L magnet (2) is cut off, the permanent magnet (3) remains separated by the spring (5).
