摘要： A liquid level detection device unit includes a liquid level detection device configured to detect a liquid level of liquid stored in a tank, and a fixing member fixing the liquid level detection device to inside of the tank. The liquid level detection device includes a device body, at least one terminal electrically connected to a detection unit in a housing of the device body, and a detection wire in which one end is electrically connected to an exposed part of the terminal exposed from the housing. At least one through opening is provided on an attachment surface of the fixing member so as to face the exposed part of the terminal and prevent the liquid from staying in a connection portion between the terminal and the detection wire.

摘要： A sensor housing of a fluid level sensor includes a peripheral wall portion and a lead wire inserting portion. The peripheral wall portion forms a hollow space penetrating in the depth direction of the sensor housing and is formed in a manner of surrounding the periphery of a terminal area of a lead frame. The lead wire inserting portion is formed by notching the peripheral wall portion in the depth direction of the sensor housing. The lead wire inserting portion consists of a first inserting portion into which a lead wire extending from the terminal area is inserted and a second inserting portion into which the lead wire is inserted after passing through the first inserting portion and holds the lead wire in a manner of bending the lead wire in a crank shape. With this configuration, the fluid level sensor can prevent leak current generated on the terminal area and thus can connect a conductive wire (the lead wire) used for connection with an external circuit with the terminal area in good condition.

摘要： A liquid level detecting device includes a sensor housing, a holder held rotatably by the sensor housing, a float arm fixed to the holder, a float attached to the float arm and following a surface level of liquid stored in a tank, a magnet provided in the holder, and a Hall element detecting a displacement of the magnet. The float arm is fixed to the holder so as to extend in a direction perpendicular to a rotation axis of the holder. The sensor housing has stoppers which restrict a rotation angle range of the holder to a first rotation angle by bringing a portion of the float arm, which is positioned between a tip of the float arm and the rotation axis, into contact with one of the pair of first stoppers.
