PROBLEM TO BE SOLVED: To provide a solenoid valve driving device, capable of preventing vibration and noise when a valve is seated by reducing the seating speed and improving the durability of the valve. SOLUTION: A valve opening solenoid 61 and a valve closing solenoid 62 are provided under an armature 4 integrally operated with a valve 2 and above the armature 4, respectively. The valve 2 is energized from upward and downward by springs 51, 52. A period when an electrification control means 8 to control electrification of both solenoids 61, 62 turns the solenoid 62 on and off in the meantime from starting electrification of the valve closing solenoid 62 to seating the valve 2 during closing the valve is set, so that the valve 2 can be sufficiently decelerated in an off-period to smoothly seat the valve 2.
