PROBLEM TO BE SOLVED: To provide a fuel supply device having a passage in a compact structure allowing a reduction in the size of the device.SOLUTION: A fuel supply device 1 includes a holder part 6 to be joined to a base member 5 while holding a fuel pump 4. Each of an exhaust passage 38 for exhausting vapor generated by the fuel pump 4, a suction passage 39 for sucking fuel into the fuel pump 4, and a discharge passage 40 for supplying the fuel discharged by the fuel pump 4 to the external is divided in two in a direction perpendicular to its extending direction. A passage part on one side of each of them is formed on a base side joint face 14 of the base member 5, and a passage part on the other side is formed on a holder side joint face 15 of the holder part 6. The exhaust passage 38, the suction passage 39 and the discharge passage 40 are located adjacent to one another in the direction perpendicular to their extending directions. |
