Abstract

PURPOSE:To provide the large driving force of the electromagnetic output device and to enable rapid response at the device by engaging a cylindrical permanent magnet with a cylindrical case formed of magnetic material perforated with an axial hole at a peripheral projection wall internally projected on both end faces. CONSTITUTION:The cylindrical case 1 formed of magnetic material is formed of a cylinder 2 and side plates 3 for closing the holes at both ends of the cylinder 2, and is also formed with axial hole 4 with peripheral projection walls 5a, 5b at the centers of the side plates 3. A cylindrical permanent magnet 5 is engaged with the case 1, and the walls 5a, 5b are magnetized in the same polarity. A plunger 8 made of magnetic material is fixedly mounted at the center of the output shaft 9 formed of a magnetic material, the output shaft 9 is journaled in the hole 4 and is inserted through a bearing 10, and is thus slidably arranged between the end faces of the walls 5a and 5b, and an exciting coil 7 is wound on the outer periphery thereof.
