PROBLEM TO BE SOLVED: To provide a fuel supply device which can hold the posture of a pump with a simple structure, and which can restrain transmission of vibration from the pump while preventing generation of vehicle noise. SOLUTION: Since a rubber vibration insulator 2 having a semi-circular ring-like shape is provided on its one side end outer peripheral part, the posture of a pump 1 can be held, and since a pump abutting surface 22a which receives main vibration from the fuel pump 1, and a bracket abutting surface 21 are provided being diametrically spaced from each other, the vibration transmission distance can be set to be longer. Further, since vibration can be led into a space 4 which is defined between an opposite end face 24 which is in an axially projected plane of the pump abutting surface 21, and a bracket 3, the vibration can be effectively attenuated. Further, since protrusions projected toward the bracket and each having a tip end having an extremely small area making contact with the bracket, are formed circumferentially in the space, it is possible to hold the posture of the pump and to minimize the transmission of vibration.
