PROBLEM TO BE SOLVED: To provide fuel feeding device to facilitate manufacture and suppress deterioration of performance and provide excellent sealing ability. SOLUTION: A cylinder 7 having a bore 70 for reciprocating a plunger is fixed at the internal part of a housing 1, and the cylinder 7 fronts on the peripheral wall through-hole 12 of the housing 1 and has a cylinder through-hole 71. One of a solenoid valve 8, a check valve 2, and a fuel suction cylinder 3 is fitted in the peripheral wall through hole 12, a tip part extends over a gap (d) between the inner peripheral surface of the housing 1 and the outer peripheral surface of the cylinder 7 and fitted in the cylinder through-hole 71. A gap between the tip part and the cylinder through-hole 71 is sealed by a seal ring 9. This constitution facilitates manufacture and suppresses deterioration of performance, and realizes a fuel feeding device having excellent sealing ability. |
