Abstract

See full text

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 actuator 1 having a point of amplified displacement includes: a displacement amplification mechanism 1A made of a magnetic material and having two surfaces 2as, 2bs that form a gap 5 therebetween; and a coil 6 provided in the displacement amplification mechanism 1A. A magnetic flux is generated by passing an electric current through the coil 6, thereby generating an attraction force between the surfaces 2as, 2bs. The attraction force displaces the point of amplified displacement.
