PROBLEM TO BE SOLVED: To shorten intervals between respective stages of injection to a combustion chamber of an internal combustion engine by improving a magnet valve for controlling an injection valve of a fuel injection device wherein a nozzle needle/tappet device 15 is provided, opening and closing of the device 15 is performed by pressure loading and discharge of a control chamber 13, the magnet valve is provided with an electromagnet 2 and a movable element 20, the movable element 20 is loaded to a closing direction to a valve seat 11 by a valve spring 3, and the valve seat 11 is opened and closed by a closing body 1 for discharging the control chamber 13. SOLUTION: The movable element 20 is an integral component equipped with a movable plate 20.1 and a movable pin 20.2. Buffer members 25, 40, 42, 43, 36, 46, 48, and 51 for damping the lowering movements of the movable element 20 to the valve seat 11 are arranged on a lower side 41 of the movable plate 20.1.
