I found a frequency equation of the torsional vibration of a conical bar with circular discs at its both ends, then defined the dimensionless value "s" that indicates the effect of the moment of inertia of the circular disc. In the special cases of "s", i.e. ; for the conical bar with a circular disc at its one end, the natural frequency of fundamental order is found, when the boundary conditions are as follows : (1) both ends are free. (2) one end (with no disc) is fixed. And the change of this natural frequency in connection with "s" and the radius ratio of both ends of the conical part is clearly pointed out. At the same time, the problems of simple conical bar (both ends free ; one end fixed, both ends fixed) are solved.
