<P>PROBLEM TO BE SOLVED: To provide a fuel supply device capable of reducing a pump operation sound, by restraining propagation of the pump operation sound to a fuel tank external part. <P>SOLUTION: This fuel supply device 1 includes a fuel pump 3 arranged in a fuel tank 2 and sucking and forcibly feeding fuel in the fuel tank 2 to an internal combustion engine by rotating an impeller 47, and a fuel suction port 41 for communicating the inside and outside of the fuel pump 3 along a rotary shaft 30b of the impeller 47, is formed in the fuel pump 3. The fuel suction port 41 is connected with a fuel introducing pipe 51 for introducing the fuel into the fuel pump 3, and an operation sound reducing member 63 having an upper surface 63a opposed to an opening surface 41a of the fuel suction port 41, is arranged on a plane of projection of the fuel suction port 41 in the fuel introducing pipe 51. <P>COPYRIGHT: (C)2013,JPO&INPIT |
