Abstract
A liquid level detecting device to be disposed in a liquid tank includes a body, a float arm having a float to be disposed in liquid, a resinous arm holder fixed to the body to hold the float arm so that the float arm moves as a level of the liquid changes, a circuit board fixed to the body, an elastic metal plate member having a sliding contact which slides on a sliding surface of the circuit board under a biasing force and a fixing member for fixing the elastic metal plate member to the arm holder. The resinous arm holder has an engagement hole portion and the fixing member has at least a pair of claws which extends along a slit between them and inserted into the engagement hole portion so that the pair of claws elastically deforms in a direction to narrow the slit.
