摘要:
A vibration gyroscope includes a cross-shaped vibration member having two axes perpendicular to each other, an excitation structure for generating a bending vibration such that vibrations along the two axes of the vibration member have opposite phases, and a detecting structure for detecting angular velocities around the two axes of the vibration member during excitation of the bending vibration on the basis of bending displacements.
