PROBLEM TO BE SOLVED: To provide an electromagnetic driving device designed such that the axes of an electromagnetic driving device and electromagnetic valve are shortened while driving force for moving a plunger is ensured more satisfactorily.SOLUTION: In a solenoid part 10 of an electromagnetic valve, a fixed core 11, cylindrical coil 12, and plunger 13 are accommodated in a bottomed cylindrical case 15. The case 15 has an internal wall face 16a opposite one end face 12a of the coil 12 in its axial direction, and also includes a ring core 16 to which one end of the fixed core 11 is fitted. The one end face 12a of the coil 12 inclines so as to approach the other end face of the coil 12 towards the inner periphery side from the outer periphery side. The ring core 16 of the case 15 is formed such that the internal wall face 16a approaches the other end face of the coil 12 towards the inner periphery side from the outer periphery side and inclines along the one end face 12a. |
