Abstract

A viscosity measurement unit includes a first stage having a first surface, a second stage having a second surface and configured to rotate with the second surface which is opposed and in proximity to the first surface, a motor including a motor body and a shaft that is an output shaft of the motor body and configured to rotate synchronously with the second stage, a fixed member arranged to rotatably support the shaft and the motor body, and a strain gauge unit fixed to the fixed member and configured to be biased by a contact of the motor body when the motor body rotates in a first direction with respect to the fixed member.
