ABSTRACT:
A gyrosensor has a weight. A plurality of deformable support portions support the peripheral portion of the weight. A driving device sequentially deforms the respective support portions to move the weight along a predetermined circular path. A detector detects an angular velocity acting upon the weight in accordance with a deviation of an actual circular path of the weight from the predetermined circular path.
