摘要

PROBLEM TO BE SOLVED: To provide a structure for taking out an electric connecting part and a high pressure fuel connecting part from a fuel injection valve in a rocker chamber in a common rail type fuel injector. SOLUTION: A base end part of the fuel injection valve 1 is arranged in the rocker chamber 8, and an electric connector part 11 and a high pressure fuel supply port 9 are mutually extended in the direction for penetrating through a rocker cover 7 in parallel from the base end part. An oil seal member 16 for sealing a taking-out part of a high pressure fuel pipe 10 and the electric connector part 11 is fixed to the rocker cover 7, and the electric connector part 11 is exposed outside via the oil seal member 16. While the high pressure fuel pipe 10 is connected to the high pressure fuel supply port 9 by a cylindrical nut 2 inserted from the outside via the oil seal member 16 to seal the outer periphery of the cylindrical nut 24 by the oil seal member 16.
