Abstract
A gyroscopic apparatus includes two gyro sensors having substantially the same structure. The two gyro sensors are arranged on first and second major surfaces, respectively, of a mounting base so that the gyro sensors have an approximately 180-degree rotation symmetry about a virtual rotation axis penetrating the mounting base substantially parallel thereto in the same direction as rotation detecting axes. The outputs of the two gyro sensors are added, and the sum is output. Thus, the output of the gyroscopic apparatus is much less susceptible to impact from a specific direction, and a high detection accuracy can be maintained.
