装置。[Claims for Utility Model Registration] A pair of electrodes connected to a detection circuit on a fixed member are supported on a supporting arm, and the supporting arm is engaged with an elevating mechanism so that the supporting arm can be raised and lowered relative to the fixed member. In the liquid level detection device, the lifting mechanism detects the liquid level by infiltrating a pair of electrodes into the liquid via the supporting arm, and the supporting arm is disposed between the supporting arm and the fixing member. A liquid level characterized in that at least a pair of conductive elastic members are provided which are biased in a direction to engage the lifting mechanism, and the pair of electrodes are connected to the detection circuit via the pair of elastic members. Detection device.
