Abstract
An electromagnetic actuator includes a mover, a stator, a bobbin module, and a first annular seal member. The bobbin module includes: a through hole, through which the stator passes along an axis line; a bobbin side receiving part, adjacent to an outer side of one end opening of the through hole and receiving the first annular seal member; and a protrusion, protruding from an inner wall surface near the one end opening. The stator includes: an outer peripheral fitting part, fitted into the protrusion; and a stator side receiving part, receiving the first annular seal member in cooperation with the bobbin side receiving part. The bobbin module and the stator define a communication path that communicates from an internal space of the through hole deviated from the protrusion to the first annular seal member in an assembled state in which the outer peripheral fitting part is fitted into the protrusion.
