PROBLEM TO BE SOLVED: To provide a pressure accumulation pipe for a fuel feeder which ensures the required fuel volume with a simple configuration without increasing the length, and is ready for the super high pressure. SOLUTION: A rail hole 19a of a predetermined diameter is formed inside a body part 19 of a common rail 13. A plurality of branched parts integrated with the body part 19 include a branched part 22 for feeding the fuel, branched parts 23a-23d for distributing the fuel, and third branched parts 24a and 24b. The third branched parts 24a and 24b are formed so that the outer circumference thereof forms a male screw part, and a communication hole 29 having no reducer part inside is formed therein. A pipe 30 is formed in a U-shape, and both ends 30a thereof are formed substantially spherical. The pipe 30 is freely inserted in through holes of two nut parts 27, the male screw part and a nut part 27 are engaged with each other with both ends 30a not-released from the through holes, and the pipe 30 is connected to the third branched parts 24a and 24b. A pressure accumulation chamber comprises the rail hole 19a and the pipe 30. |
