Abstract:
PROBLEM TO BE SOLVED: To evenly apply a depressing force to a fuel injection valve and to avoid transmitting a rotational force to the fuel injection valve when tightening a bolt. SOLUTION: A female screw part 14 to fix a holder 6 with a bolt 5 while forming a mounting hole part 4 for a fuel injection valve 1 to a cylinder head 3. The holder 6 comprises a cylindrical part 11 in which a rear end part of the fuel injection valve 1 is fitted with play and a cylinder part 12 to which a through hole for the bolt 5 is formed. The holder 6 is fixed to the cylinder head 3 with the bolt 5 being interposed by a pair of washers 15, 16 having a curbed surface along an outer surface of the cylinder part 12 so as to ensure degree of freedom of an axis of the cylinder part 12. The bottom washer 16 is positioned in the rotational direction of the bolt 5 against the cylinder head 3 by fitting in a groove-shaped mounting seat surface 17. A cylindrical part receiver 20 is provided between the cylindrical part 11 and a flange part 7 of the fuel injection valve 1, and a contact surface of the cylindrical part 11 and the cylindrical part receiver 20 is composed by a curbed surface curbed on a plane including an axis of the cylindrical part 11 and an axis of the bolt 5.
