Abstract

An electromagnetic actuating valve (10) of a fuel injection device (1) includes a stator (14), which incorporates an excitation coil (13) and is formed with an attraction surface (14a), an armature (16) disposed to face the stator (14), and a stopper member (15) fitted inside the stator (14). An outer peripheral surface of the stator (14) is fitted inside an upper portion (3a) of an injector body (3). The stator (14) is held between a lower surface of the housing (11) and a holding surface (15c) of the stopper member (15) in an axial direction. The armature (16) is formed with an attraction surface (16a) facing the attraction surface (14a) of the stator (14). A protruding ring (16c) protrudes from the attraction surface (16a) to face a lower surface of the stopper member (15). Thus, movement of the armature (16) is limited.
