The protective wall portion 72 of the portion 70 comes into contact with the fuel tank 10. Therefore, it is possible to prevent the thermistor harness 81 from being pinched when the fuel supply device 20 is inserted into the fuel tank 10.

Further, since the thermistor 80 is supported by the thermistor support portion 68 of the adapter 60, the distance between the thermistor 80 and the harness holding portion 70 is shortened as compared with the case where the thermistor 80 is supported by a member other than the adapter 60. can do. Therefore, the length of the thermistor harness 81 of the thermistor 80 can be shortened, and the thermistor harness 81 can be further prevented from being pinched when the fuel supply device 20 is inserted into the fuel tank 10.

Further, since the upper end portion of the thermistor harness 81 is held by the harness holding portion 70 of the adapter 60, bending deformation of the thermistor harness 81 due to resonance with vehicle vibration can be suppressed.

Further, by introducing the thermistor harness 81 into the harness holding portion 70 from the center line L side of the lid member 21, it is possible to prevent the thermistor harness 81 from falling off due to the elastic restoring force in the extension direction of the thermistor harness 81.

Further, the shielding wall portion 69 of the adapter 60 is made of resin and has an insulating property. Therefore, the shielding wall portion 69 is arranged between the pump side terminals 50a of the harnesses 50 for both pumps of the fuel pump 30, so that the harnesses 50 for both pumps can be protected from electrolytic corrosion.

Further, since the upper surface 72a of the protective wall portion 72 of the adapter 60 is formed on a horizontal flat surface, when the adapter 60 is attached to the pump case 40, the protective wall portion 72 can be easily pushed down. Assemblability can be improved.
