PROBLEM TO BE SOLVED: To disclose a technology of properly detecting the liquid level of fuel in a fuel tank.SOLUTION: A sensor device 50 is used for detecting the liquid level of fuel in a fuel tank 8. The sensor device 50 comprises a sensor body 70, a side wall 60b, a jet pump, and a flow passage 58. The sensor body 70 changes in its electrostatic capacity according to the liquid level of fuel in the fuel tank 8. The side wall 60b circles the sensor body 70 and defines a sensor chamber 68. The jet pump sends fuel outside a reserve cup 20 into the inside of the reserve cup 20 by using the flow speed of liquid boosted by a fuel pump 22. The flow passage 58 provides communication between the jet pump and the sensor chamber 68. |
