<P>PROBLEM TO BE SOLVED: To provide a fuel supply device with a cooling structure easy to form on a cover member for cooling a circuit part. <P>SOLUTION: The cover member 12 formed of a resin has a flange 13, a lower case 60, an upper case 70, and a cover 90. The lower case 60 and the upper case 70 are joined to each other to form a cooling passage 200. To the cooling passage 200, fuel is supplied from a discharge pipe 46 of a filter case 42 through a bellows pipe 18 and an inflow pipe 62 after discharged by a fuel pump 32. The cover 90 closes the opening of the upper case 70 to form a storage chamber 201 with the upper case 70. With the storage chamber 210 connected at its air outlet side to an intake manifold of an engine, an air flow from an air inlet through the storage chamber 210 to an air outlet is generated in the storage chamber 210 by negative pressure in the intake manifold generated during engine operation. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
