Electromagnetic actuator with bobbin with positioning part for positioning stator

An electromagnetic actuator comprising:

• a mover, reciprocating along a predetermined axis line;
• a first stator and a second stator, accommodating the mover to be capable of reciprocating in a direction of the axis line and arranged spaced apart in the direction of the axis line;
• and
• a bobbin, arranged around the first stator and the second stator and around which a coil for excitation is wound, wherein
• the bobbin comprises:
• a through hole, through which the first stator and the second stator pass;
• and a positioning part, partially formed in the through hole, allowing the first stator and the second stator to be fitted thereinto, and positioning the first stator and the second stator on the axis line,
• wherein the positioning part comprises a first positioning part, formed near one end opening of the through hole in the direction of the axis line and positioning the first stator, and a second positioning part, formed near the other end opening of the through hole in the direction of the axis line and positioning the second stator,
• the through hole comprises:
• a first through hole, centered on the axis line;
• and a second through hole, adjacent to the first through hole in the direction of the axis line and having a smaller diameter than the first through hole,
• the first positioning part is formed in an area of the first through hole, and
• the second positioning part is formed in an area of the second through hole.
