PROBLEM TO BE SOLVED: To prevent the occurrence of a trouble due to remarkable reduction of a suction force when a protrusion part 81 is too collapsed or the protrusion part 81 is broken and the occurrence of a trouble due to jolting of a coil. SOLUTION: A cover 8 is provided with a stopper 82 to prevent movement of a coil to a position exceeding an allowable range of coil height h, too collapse of a protrusion part 81 is prevented from occurring by a stopper 82, and a movement range of the coil is regulated such that the coil height h does not exceed the allowable range even when the protrusion part 81 is broken. Accordingly, a necessary minimum suction force demanded for a solenoid valve can be ensured. Further, when the protrusion part 81 is broken, the coil makes contact with the stopper 82, and the coil is held and jolting of the coil can be prevented from occurring. COPYRIGHT: (C)2005,JPO&NCIPI
