Abstract:
A fuel injection valve is attached to an engine and to have an annular seal material attached thereon. The seal material is attached to a first reduced diameter part. In a use state where a body is inserted in an attachment hole formed at a predetermined position of the engine and a gas pressure that is equal to or higher than a predetermined pressure is applied to the seal material from its nozzle hole-side, the seal material is pressed against a first tapered part by the gas pressure to be compressively deformed, and a clearance between an inner peripheral surface of the attachment hole and an outer peripheral surface of the body is sealed with a compressively-deformed part of the seal material. A taper angle of the first tapered part is set in a range from 10 degrees to 20 degrees.
