<p>PROBLEM TO BE SOLVED: To improve on-board property on a vehicle by penetrating a connector into a penetrating hole arranged on a wall part, and interposing an annular seal member such as an O-ring between the outer peripheral part of the connector and an inner circumferential surface of the penetrating hole, in the case where a fuel injection pipe is connected to a fuel injection valve penetrating the wall part such as a rocker case. SOLUTION: When a fuel injection pipe 18 is installed, a connector 20 is set with its centerpart 20a slidably penetrated into a penetrating hole drilled on the wall part of a rocker case 24, an inner connecting part 22 is formed on the inner side of the rocker case 24 by bending in a firm-set mouth shape or in a doglegged shape, and an outer connecting part 26 is formed on the outer side of the rocker case 24. A fuel passage 40 is drilled, which is bent in a firm-set mouth shape at the inside of the connector. An annular seal member 48 such as an O-ring is fit to the inside of a recessed groove arranged on the outer periphery of a center part 20a, a rotation preventive part 50 is integratedly formed with the outside of the center part 20a, and an elastic annular number 54 is interposed between the rotation preventive part 50 and the wall part inner surface of the rocker case 24.</p> |
