Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a delivery pipe provided with an inner-tube member by which improvement effects are increased in damping performance of pulsation of combustion-pressure. SOLUTION: The delivery pipe 10 has a double-tube structure in which an outer-tube member 12 and an inner-tube member 14 are provided, and a fuel passage 16 is formed between both the pipe members 12, 14. The inner-tube member 14 is formed of a flexible tubular material. The inner-tube member 14 is formed in an oblate shape having a pair of platy parts 14a parallel with each other in the direction facing to fuel outlets 21 for connection of injectors formed in the outer-tube member 12. If the width of the platy parts 14a is set W, and the space between each of the platy parts 14a is set D, the oblateness R expressed by W/D is set to 1.2≤R≤7.5. COPYRIGHT: (C)2010,JPO&INPIT
