PROBLEM TO BE SOLVED: To provide a fuel injection valve which stably adjusts valve lift quantity regardless of unstable form accuracy of a pressing-in part in the case where valve lift quantity adjustment by pressing-in of a sucking member is performed. SOLUTION: The fuel infection valve has a metal inner cylinder member 14 for storing a movable piece 25 and a valve member 26 in an axially reciprocatable manner and for structuring a part of a magnetic circuit, a driving coil 31, a first metal outer frame member 18 arranged at outer peripheral of the metal inner cylinder member 14 for sandwiching the driving coil 31 and for forming another part of the magnetic circuit with a tip end part 18a contacting with the metal inner cylinder member 14, and a sucking member 22 for being pressed into an inner peripheral 14d of the metal inner cylinder member 14 and capable of adjusting axial direction position. The tip end part 18a of the first metal outer frame member 18 and the metal inner cylinder member 14 for contacting with the tip end part 18a form a junction J1 to be connected. A relief part R is formed between the sucking member 22 located at a same position in an axial direction as the junction J1 and the metal inner cylinder member 14. COPYRIGHT: (C)2003,JPO
