Two-degree of freedom gyro is used as the position gyro of the high-speed air craft. The author measured the drift of air-driven two degree of freedom gyro to which the forced vibration about the vertical axis was given. He pointed out the following four items as the causes of the drift. (1) The effect of air to drive the rotor; When the angle between the axes of outer gimbal and of rotor is not rectangular, the air generates the torque about the axis of inner gimbal. (2) The effect of forced vibration; Forced vibration is given to the gyro through the bearings, having the characteristic of negative frictional resistance. (3) Unbalance of mechanism; It is obvious that this causes the drift. (4) The friction of rotor bearings; He compared the results of experiments with the theory, taking into account the causes mentioned above, and obtained the good agreement.
