Title: LIQUID LEVEL DETECTOR
Abstract:
A liquid level detector is provided with a housing (10) having a first regulation part (21) and a second regulation part (31) that are fixed to a container (90, 190, 90a) and are mutually opposed in the direction of gravitational force (GD); a float (60, 260) that floats on a liquid surface and moves vertically in the direction of gravitational force so as to be regulated by contact with the first regulation part and the second regulation part; a magnet body (50) that extends along the direction of gravitational force, is held by the float, and moves vertically so as to follow the liquid surface; and a switch mechanism (40) that is held by the housing and is switched on or off by the movement past a switching plane (SWP) in the direction of gravitational force of one extension-direction magnet end face (51, 52) of the magnet body. The housing is assumed to be disposed in a first or second orientation. Regardless of the orientation of the housing, the float is disposed between the first regulation part and second regulation part in an orientation in which a specific lower part (62, 262) is oriented in the direction of gravitational force. A first distance (D1) from the switching plane to the first regulation part and a second distance (D2) from the switching plane to the second regulation part are both longer than the distance (LB) from the magnet end face to the lower part.
