とにより、洩れた燃料を燃料溜りに集め易くできる。As described above, the fuel leakage detection device for a diesel generator according to the present invention has a lid on which a fuel reservoir is formed detachably provided on a lid mounting seat for removing an oil pan, and a fuel reservoir provided on the fuel reservoir. Since the sensor is activated when a predetermined amount of fuel is accumulated, it is possible to detect that a predetermined amount of leaked fuel has accumulated in the fuel reservoir, and it is possible to prevent ignition of the fuel scattered in a mist state in the casing. Further, the leaked fuel is accumulated in the fuel reservoir having a small opening area, and thus it is difficult for the radiator cooling fan to draw the leaked fuel. Further, by providing a guide plate for guiding fuel to the fuel reservoir around the lid mounting seat, it is possible to easily collect leaked fuel in the fuel reservoir.
