Abstract
A solenoid device is configured to drive by electromagnetic force a valve unit in an electromagnetic valve provided to a fuel injection system. The solenoid device includes: a cylindrical core; a coil wound around the core; a casing housing the core and the coil and that covers at least one end of the core on one side in an axial direction; a terminal fixing member disposed between the core and the casing in the axial direction to fix a terminal connected to the coil; and a cylindrical member disposed on an inner circumference of the core in a manner of passing through the core and the casing in the axial direction. The cylindrical member has a protrusion that radially protrudes in a direction perpendicular to the axial direction and is held between the casing and the terminal fixing member from both sides in the axial direction.
