PROBLEM TO BE SOLVED: To provide a fuel supply device for internal combustion engine, capable of improving vibration resistance against vibrations or a shock transferred from an intake pipe member with a simple structure.SOLUTION: A fuel supply device is configured such that a pump part 35 is supported on an outer circumferential part of an intake pipe member 15 which constitutes a part of the intake pipe to intersect the axial center direction of the intake pipe member, a driving part 27a is disposed on one side edge part of the pump part which intersects the intake pipe member, and an intake connection port body 29 and a return connection port body 31 are disposed on the other side edge part. Thereby, when the fuel supply device is installed on the vehicle, not only weights of the intake connection port body and the return connection port body are added but also weights of hose members, connected to the connection port bodies, and stoppers, for stopping the hose members, or the like are added on the other edge part of the pump part, and the other end side of the pump part where the various kinds of connection port bodies exist and the one end side of the pump part where the driving part exists are easily well-balanced in weight and, by only the constraint with the hose member from the fuel tank, vibrations of the pump part and the driving part are suppressed to improve the vibration resistance. |
