Claim 0:
1. A fuel tank isolation valve of a vehicle comprising:
a first armature pulled toward an inside of a core by an electromagnetic force generated when a current is supplied to a coil;
a second armature connected to the first armature thus operating in a same direction as the first armature, and configured to open and close a flow path,
wherein the first armature and the second armature are connected so that there is no clearance in an axial direction; and
a guide and a first spring provided between the first armature and the second armature to form an armature assembly;
wherein the first spring is compressed by being supported at both ends thereof by the guide and the second armature, and a spring compression amount securing groove is formed on an upper surface of the guide; and
wherein the armature assembly is in such a manner that, before assembled inside the fuel tank isolatio valve, an undersurface of a body of the first armature is in contact with a floor surface of the spring compression amount securing groove, and, when assembled inside the fuel tank isolation valve, the guide further compresses the first spring by moving toward the second armature while being in contact with the core.
