Summary:PROBLEM TO BE SOLVED: To improve the responsiveness in driving and controlling the driving part of an electromagnetic actuator, and reduce a consumption current. SOLUTION: A capacitor 47(53) is installed which stores charge due to a counter-electromotive force generated in an open side coil 44 (closed side coil 50) when a transistor 46 (51) has changed from the communicating state to the breaking state. An auxiliary open side coil 48 (auxiliary closed side coil 54) is installed which generates a magnetic field of the same polarity as an open side coil 44 (closed side coil 50), by making a current discharged from the capacitor 47 (53) flow, when the transistor 46 (51) has changed from the breaking state to the communicating state.
