クチユエータ用磁気回路。 A magnetic circuit for an actuator in which two assemblies are assembled in which one yoke and one permanent magnet are adhesively fixed, with the different polarities of the permanent magnets facing each other, and a spacer is used to maintain the gap between the permanent magnets. In order to maintain the gap between the permanent magnets and to fix the permanent magnets and the magnetic yoke, the opposing permanent magnets and the magnetic yoke are integrally injected and extruded with resin, and the structure is fixed. Magnetic circuit for actuator.
