PROBLEM TO BE SOLVED: To prevent distortion in the radial direction of an elastic member 4c of an axial misalignment absorbing washer 4 and to prevent aged deterioration of performance of the elastic member 4c when a fuel injection valve 1 is mounted in the mounting hole 3 of a cylinder head 2 of an engine. SOLUTION: The fuel injection valve 1 applies pressure on the mounting hole 3, and the axial misalignment absorbing washer 4 receives the applied pressure. The axial misalignment absorbing washer 4 includes a recessed ring 4a having a recessed part 4a1 into which the elastic member 4c is inserted and a projected ring 4b having a projection 4b1 pressed by the elastic member 4c within the recessed part 4a1. Since the elastic member 4c is provided in the recessed part 4a1, the radial distortion of the elastic member 4c can be prevented and the aged deterioration of vibration preventing action can be suppressed.
