Level detecting means

Object of the present invention is to reduce or eliminate the contact situation between the plurality of electric wires from the detecting portion projecting. Level detecting means (1) comprises a detecting section (20), the detection unit (20) in accordance with rotation of the rotating portion (21) is rotated along with the displacement of the float, the liquid level detection position; mounting plate-shaped portion (12) , which is a surface mounting detection portion (20) of the mounting surface (12a); attached to the flange portion (11) on a tank holding a liquid; (20) toward the flange portion from the detection section (11) projecting section and second wires (31, 32). Setting branch (122) is formed by a through hole in the mounting plate portion (12), the second wire (32) through a branch (122), whereby, from the mounting face of the mounting plate portion (12) (12a) of the side around the inner surface (12b) side.
