PROBLEM TO BE SOLVED: To involve a fixing tool into an adjacent area of an injection device and to install the fixing tool apart from a positional critical load supporting area by providing a fulcrum part with which a first tip part engaged to a fuel injection device main body, a fixing force receiving part and an upper surface of a fixing tool are in rolling-contact by being engaged to a fulcrum part on an engine while the injection device is used. SOLUTION: An injection device fixing tool 12 on which a lock nut 15 and an adjusting screw 14 are mounted is slidably positioned so that each arm of a first tip part 16 may face one of a pair on an opposite side of a flat surface 18 at a recessed portion provided on an upper part of an injection device main body. A circular arc lug 19 is mounted on a fixed shoulder part 17 of an injection device and the adjusting screw 14 provided on the side of a second tip part is seated at a recess of thrust fastening hardware. The adjusting screw 14 is twisted in a direction that a projection 20 on an upper surface of the fixing tool 12 is brought into slight contact with a pad 21 on a lower surface of a fluid rail 9. In this point, the projection 20 acts as a fulcrum and fixed load is applied to the shoulder part 17 of the injection device by further fastening of the adjusting screw 14.
