Abstract
A viscometer capable of measuring a viscosity in high precision by increasing a transmission efficiency of a rotational torque while simplifying a structure and facilitating a down-sizing is provided. A viscometer includes: a hollow shaft motor; a needle shaft piercing through a hollow driving shaft of the hollow shaft motor and having an upper end side and a lower end side supported to be rotatable; a spring configured to transmit a driving force of the hollow shaft motor to the needle shaft; a spindle attached to the lower end side of the needle shaft; and a phase difference detection unit configured to detect a rotational phase difference between the hollow driving shaftand the needle shaft.
