Abstract: An inside projection is formed in one piece with a second tubular member and projects in a tubular form toward a third tubular member, and an outside projection is formed in one piece with the third tubular member and projects in a tubular form toward the second tubular member, while an inner wall of the outside projection is engaged with an outer wall of the inside projection. Another inside projection is formed in one piece with the second tubular member and projects in a tubular form toward a first tubular member, and another outside projection is formed in one piece with the first tubular member and projects in a tubular form toward the second tubular member, while an inner wall of the outside projection is engaged with an outer wall of the inside projection.

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.

Abstract: A needle has a large-diameter portion, an outer diameter of which is larger than that of a shaft portion of the needle. A needle-side tapered surface is formed at the large-diameter portion on a valve closing side thereof, wherein the needle-side tapered surface is inclined by a needle angle with respect to a center axis of the needle. A core-side tapered surface is formed at a movable core, wherein the core-side tapered surface is inclined by a core angle with respect to the center axis of the needle. The needle and the movable core are brought into contact with each other via the needle-side and the core-side tapered surfaces. The needle angle and the core angle are made to be equal to each other.
