Beschreibung
Zusammenfassung:	An electromagnetic actuator includes an electromagnetic coil, a yoke serving as a magnetic path of a magnetic flux of the electromagnetic coil, an armature configured to move in an axial direction while being attracted by the yoke by energization of the electromagnetic coil, and a housing that houses the armature. The armature and the housing are coupled to each other by an engagement structure in which protrusions provided on one of the members engage with engagement grooves formed in the other one of the members. At least a part of the engagement groove is inclined with respect to the axial direction. When the armature moves while being attracted by the yoke, the protrusions of the armature slide along the engagement grooves of the housing, and the armature turns relative to the housing along the inclination of the engagement grooves.
