<P>PROBLEM TO BE SOLVED: To provide a gyroscope sensor which is hard to influence by a working environmental condition, which suppresses the variation of a natural frequency at the time of shift to a sensing mode (asymmetry or symmetry) from an actuation mode (symmetry or asymmetry), which is hard to influence of the working environmental condition suitable for highly precise instrumentation, and, moreover, has a sufficient shock resistance or breakdown-proof nature. <P>SOLUTION: The gyroscope sensor of tripod tuning fork which consists of a spring material is composed. In this case, the gyroscope sensor is formed from one plate of a material having piezoelectricity, and a vibrator having a superficial geometry which has a proximal which connects three legs, a supporting member which fixes the gyroscope sensor to the base, a plurality of coupling sections having a width narrower than one-third of the width of the proximal for connecting the above-mentioned proximal and the supporting member, and a plurality of coupling sections having a width narrower than one third of the width of the proximal, is used. <P>COPYRIGHT: (C)2007,JPO&INPIT |
