In a solenoid actuator, spacers (541, 542) made of nonmagnetic materials are arranged between permanent magnets (521, 522) and corresponding adapters (551, 552) based on magnetic force of the permanent magnets (551, 552) to from a magnetic gap. Thus, magnetic attraction that the permanent magnets (521, 522 ) apply to plungers (651, 652) falls in an expected range. |
