Vibrationskreisel

摘要

A vibrating gyroscope (10) includes a vibrator (12). The vibrator (12) is installed to a work plate (32) via supporting members (22a, 22b) and so on. A work cover (44) is installed to the work plate (32) so as to cover the vibrator (12) and so on. The vibrator (12), the work plate (32), the work cover (44) and so on are installed to one main surface of a circuit board (58). Both end portions of the work cover (44) and both end portions of the circuit board (58) are surrounded by two cushion members (78). The work cover (44), the circuit board (58), the cushion members (78) and so on are contained in a case (88). Though bottom faces and top faces of the cushion members (78) respectively touch a surface of a packing (98) on a bottom board (90) of the case (88) and an inside face of a case body (100), the work cover (44) and the circuit board (58) do not touch the case (88).
