| description | PROBLEM TO BE SOLVED: To provide a fuel supply device for a fuel injection valve of intra-cylinder injecting type, in which a backup ring tightly and properly keeps contacts with the inner circumferential surface of the connection hole of a distribution connector and the bottom surface of a seal groove at all times by absorbing the misalignment of a mounting hole in a cylinder head from the distribution connector, capable of preventing a seal member from ranging out of the seal groove certainly without causing damage.SOLUTION: The seal groove 10 is formed at the periphery of a fuel inlet cylindrical part 6, and the backup ring 12 interposed between the seal member 11 and the side wall 10a of the seal groove 10 on the inside in the axial direction is composed of the inner ring member 12a in annular shape made of resilient material and fitting to the bottom surface of the seal groove 10, and the outer ring member 12b made of a hard material, whose inner circumferential surface is fitted to the peripheral surface of the inner ring member 12a and whose peripheral surface is fitted to the inner circumferential surface of the connection hole 16. |
