Abstract

A liquid level detector may include a float, an arm member, and a magnetic sensor unit. The float may be attached to the arm member. The arm member may be configured to convert a movement of the float in a vertical direction to a rotational movement. The magnetic sensor unit may include a magnetic sensor and covers. The covers may cover the magnetic sensor. The covers may include a first cover, and a second cover. The first cover may be made of a first resin material. The first cover may cover a whole surface of the magnetic sensor. The second cover may be made of a second resin material different from the first resin material. The second cover may cover a whole surface of the first cover.
