Abstract: PROBLEM TO BE SOLVED: To prevent the transmission/reception efficiency in ultrasonic waves from decreasing, a vibration frequency from being changed, and the like by a brush 3 for wiping off deposits on a vibration surface 3a in an ultrasonic vibrator 3 for causing erroneous measurement in an interface-measuring apparatus for measuring the position in an interface that is formed at the lower portion in liquid 07 in a precipitation bath from a floating suspension object by the transmission/reception of ultrasonic waves. SOLUTION: A washing frame 5 in a cylindrical cage shape has a number of blades 54 and a brush 53 on the periphery and the bottom, respectively, of a frame that becomes the base frame, receives the pressure of water 20 from a nozzle section 11 in the blades 54 in washing, and is rotated and lifted with a guide pipe 6 as an axial pipe while surrounding the vibrator 3. In this case, the brush 32 is in contact with the vibration surface 3a for rotation, and at the same time wipes out the vibration surface 3a.
