Abstract
When a fuel injection valve is mounted on an engine, a distance between a core and an armature during non-energization of a coil can be prevented from becoming narrow. The coil is arranged inside the core, and a body is fixedly secured at its one end to an end of the core. A housing is arranged outside the coil with its one end abutting a cylinder head. A cap is arranged at the other end of the housing, and abuts at its side opposite to the housing with a fastening unit. The armature is arranged for reciprocation inside the body, and is magnetically attracted to the magnetized core. A gap is formed between the housing and the body, with the cap and the core being fixed to each other, and upon mounting the valve on the engine, the housing and the fastening unit abut the cylinder head and the cap, respectively.
