PROBLEM TO BE SOLVED: To provide an electromagnetic actuator capable of fixing a solenoid in a storage space by preventing lowering of suction force of an armature.SOLUTION: A solenoid 12 is pressed and fixed to the bottom of a storage space α by a penetrating and holding member 21 penetrating through an armature 13. The penetrating and holding member 21 is assembled to the inside of an inner peripheral pole of a stator core 17 and is disposed to penetrate through a through-hole of the armature 13. Each component is assembled in the storage space α, an injection nozzle 2 is assembled via an orifice plate 23, and a retaining nut 4 is fastened. Accordingly, an armature holder 14 is pressed to the inside of the storage space α and the solenoid 12 is fixed to the inside of the storage space α via the penetrating and holding member 21. An outer diameter dimension of the armature 13 can be increased and lowering of suction force of the armature 13 can be prevented by preventing a decrease in magnetic pole area since the penetrating and holding member 21 penetrates through the armature 13. |
