PROBLEM TO BE SOLVED: To provide a multi-functional displacement sensor advantageous in cost by integrating (compounding) single-function displacement sensors for detecting the water level, vibration, opening and closing of a door, and the like, at a customer's demand while the conventional washing machine is loaded with a displacement sensor, a vibration (rocking detecting) sensor, a door switch, and the like, respectively. SOLUTION: In a displacement sensor displacement detecting part 11, a magnetic member 34 is provided on an upper part of an upper case 20 engaged with a lower case 25, a metal ring 93 is provided on an outer peripheral part of the upper case 20, and an oscillating coil 40 is provided on a diaphragm reinforcing plate 44 (46) side disposed on the upper part of a diaphragm 47 sandwiched between the upper case 20 and the lower case 25. The detecting part 11 is taken as a base, rocking is detected by a lever body B90 engaged with the magnetic member 34, and the opening and closing of the door is detected by a lever body A91 engaged with the metal ring 93.
