PROBLEM TO BE SOLVED: To provide a solenoid valve device which is made compact without allowing the valve device to be large-sized and which prevents the occurrence of cavitation and corrosion in an armature and in its peripheral members, and further to provide an engine fuel injection device with the same. SOLUTION: In the solenoid valve device, an armature is formed with a passage hole which penetrates an attracting surface at a solenoid device side and a backside at a valve body side and is mounted with a thin-plate valve. When the armature has been attracted, the thin-plate valve is bent to open the passage hole and thereby a minute gap formed between an end face of a solenoid unit and the attracting surface of the armature and an armature chamber in which the armature exists are allowed to communicate with each other. Then, when the attracting force is removed to return the armature by means of a returning spring, the thin-plate valve is restored to close the passage hole. COPYRIGHT: (C)2008,JPO&INPIT
