Abstract
An angular rate sensor includes an oscillator having a pair of arm portions extending parallel to each other, a stem portion continuously formed to the arm portions, a driving member for oscillating the arm portions in directions opposite to each other, and a distortion detecting member for detecting a distortion of the arm portions in a distorted direction of the arm portions caused by a Coriolis force. The angular rate sensor further includes a correction driving member for driving the arm portions in the distorted direction of the arm portions, and a correction circuit for controlling the correction driving member to drive the arm portions in such a direction as to cancel a false distortion of the arm portions. The false distortion is detected by the distortion detecting member without the arm portions being subjected to the Coriolis force.
