Abstract
There is provided an electromagnetic actuator which can secure a sufficient thrust force at least at a certain level over a wide range of displacement. The electromagnetic actuatorhaving a point of amplified displacement includes: a displacement amplification mechanismA made of a magnetic material and having two surfacesthat form a gaptherebetween; and a coilprovided in the displacement amplification mechanismA. A magnetic flux is generated by passing an electric current through the coil, thereby generating an attraction force between the surfaces. The attraction force displaces the point of amplified displacement.
