(54) Electromagnetic actuator


(57) An electromagnetic actuator (7) includes a pair of core assemblies (12a, 12b) and a spacer (24). The armature (11) is provided between the pair of core assemblies (12a, 12b). The spacer (24) is formed by molding to be integral with a coil (20) provided in electromagnets (30a, 30b) of the core assemblies (12a, 12b) and is located between the electromagnets (30a, 30b). And relative positions of the pair of electromagnets (30a and 30b) to each other are determined by the spacer (24). A space to allow the armature to reciprocate is secured between the core assemblies (12a, 12b) by the spacer (24).
