Abstract

An electromagnetic actuator () includes sensor magnets () disposed correspondingly to plungers (), respectively. The electromagnetic actuator () further includes a sensor core () made of a magnetic material and disposed in a position through which magnetic fluxes from the plurality of sensor magnets () can flow, and a magnetic sensor () that is disposed in a part of the sensor core () through which the magnetic fluxes of the plurality of sensor magnets () can flow in common, and that detects the magnetic flux, which varies in accordance with respective positions of the plurality of plungers ().
