の範囲第(1)項記載の液面検出装置。[Claims for Utility Model Registration] (1) A case forming an internal cavity into which engine oil flows; a float that floats within the internal cavity due to the buoyancy of the engine oil; a permanent magnet fixed to the float; The liquid level detection device includes a switch that is turned on and off by the movement of the permanent magnet when the float floats, a passage provided in the case through which engine oil passes, and a bimetallic valve that opens and closes the passage. A liquid level detection device characterized in that a circular flat part with an almost infinite radius of curvature is formed in the center of a bimetallic valve, and a curved or bent circular peripheral part is formed around the flat part. (2) The center part of the bimetallic valve is fixed by a mounting screw inserted through a hole drilled in the center of the circular flat part, and the circular peripheral part of the bimetallic valve is fixed to the flat valve seat of the case. When the engine oil in the inner cavity is heated to a certain temperature, the bimetallic valve is inverted due to thermal deformation, and the outer circumference of the bimetallic valve is separated from the valve seat of the case to open the passage. A liquid level detection device according to claim (1) of the utility model registration.
