[Problem] To provide a float position sensor with a simple structure in which, even when a float is moved after the power is turned off, adjustment is not particularly necessary when the power is turned on next time. [Means for Resolution] A float position sensor including a float and a magnetic sensor provided in a lateral direction with respect to a movement direction of the float for detecting a change of a magnetic field caused by movement of the float, characterized in that the change of the magnetic field caused by the movement of the float is detected by the magnetic sensor through a movable magnet provided in the vicinity of the magnetic sensor. |
