A liquid surface sensing device is installed in a fuel tank having an opening in a ceiling part. The opening is closed by a flange with a gasket constituted by an elastomer providing a seal between the flange and a peripheral edge of the opening. The liquid surface sensing device being assembled to the flange includes a sensing unit disposed vertically below the flange and sensing a liquid surface of a liquid, a lead wire connecting the sensing unit to an external device via the flange, and a guide bending the lead wire extending diagonally downward from the flange to form a valley portion to direct the lead wire diagonally upward.

Liquid surface sensing device

A liquid level detection device is provided with a fixed body and a rotating body, having a float and an arm. The arm has an insertion portion inserted in the rotating body and an extending portion extending straight and bent relative to the insertion portion. The rotating body has an insertion hole in which the insertion portion is inserted, a holding portion having a receiving opening receiving the extending portion and holding the extending portion received by the receiving opening, and a stopper releasing the receiving opening from a blocking state in which a blocking portion blocks the receiving opening. The stopper has a sliding surface portion on which the extending portion is allowed to slide. A thickness of the blocking portion at a tip end of the sliding surface portion is greater than a diameter of the extending portion.
