ABSTRACT:
A viscosity detector includes an electromechanical vibrator having a central axis and capable of vibrating about the central axis, a transmission shaft having one end thereof connected coaxially to the vibrator, and a detector member connected coaxially to the other end of the transmission shaft. The detector member is immersed in liquid the viscosity of which is to be measured, and is vibrated about the central axis of the vibrator within the liquid by the vibration of the vibrator transmitted through the transmission shaft to detect the viscous resistance of the liquid at a circumferential surface of the detector member. The vibrator converts the detected viscous resistance into an electric signal.
