Abstract
A fuel injection valve includes a housing having a nozzle hole, a valve seat, and a fuel passage; a needle that is accommodated in the housing to be capable of reciprocating in an axial direction of the housing and that opens or closes the nozzle hole; a coil; a fixed core; a movable core; a shift permitting member that is provided between the housing and an internal-combustion engine to permit a shift of an attachment position at time of attachment of the housing and the engine; and a friction reducing part that is provided between the engine and the shift permitting member to reduce friction between the engine and the shift permitting member. The friction reducing part permits displacement of the housing in a direction perpendicular to the axial direction of the housing.
