PURPOSE:To allow a bilateral action by providing a fist and a second permanent magnets which can be slidden in the approaching and separating directions against one end of a fixed iron core along a guide, and taking out a sliding force of each permanent magnet. CONSTITUTION:A first and second permanent magnets 4a, 4b are disposed in the way that the S-poles of these magnets are opposed to each other across a fixed iron core 3. In generating magnetic poles on both sides of the core 3 by flowing a current through the coil 1, the first magnet 4a is attracted and the second magnet 4b is repulsed on account of their magnetic polarities, forcing the manuplating lever 6b to move in arrow direction (A). Reversing the polarity of voltage impressed on the coil 1 can move the lever in arrow direction (B). |
