Title:
LIQUID-SURFACE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/139257
Kind Code:
A1
Abstract:
To provide a liquid-surface detection device having a small parts count, whereby electrolytic corrosion can be suppressed. A liquid-surface detection device (10) has a detection part (31) for detecting magnetism, a plurality of terminals (35-37) connected by one end thereof to the detection part (31), a first retaining body (30) for retaining the terminals (35-37) and rotatably supporting a magnetic part (20), a second retaining body (50) attached to the first retaining body (30), and electroconductive parts (61-63) retained by the second retaining body (50) and connected to other ends of the terminals (35-37). The first retaining body (30) has substantially U-shaped surrounding parts (71-73) for surrounding other ends (35a-37a) of the plurality of terminals (35-37), respectively. The second retaining body (50) has dividing parts (54, 55) overlapping between the surrounding parts (71-73).
