PROBLEM TO BE SOLVED: To provide a liquid surface level detector capable of accurately maintaining a detection accuracy of a liquid surface level.SOLUTION: A liquid surface level detector 100 includes: a main body 101; a float detector 110 and a float 120. The main body 101 is formed into a bottomed cylindrical shape with a stem 102, a flange part 104, a fitting part 105, and a storage part 106 provided. The float detector 110 is constituted of a lead switch for detection a magnetic field of the float 120, and is provided inside the stem 102. The float 120 has a buoyant force to float in a liquid L to be detected, and is formed in a cylindrical shape to generate the magnetic field. An end part on the side of a float stopper 103 in a stem through-hole 121 of the float 120 is formed with four radial-direction protrusions 122. The radial-direction protrusions 122 are formed to project outward the inner peripheral surface of the stem through-hole 121 of the float 120 and the end face on the side of the float stopper 103 in the float 120, respectively.SELECTED DRAWING: Figure 1 |
