vibrator portion 1 has a configuration wherein the vibrator 2 is clamped and supported in midair by the support members 3 4 6 and 7 held and adhered to the vibrator base 5 the vibrator base 5 is preferably constituted of a high specific gravity resin material having a specific gravity of about 3 0 or greater the vibrator base 5 is molded of a material obtained by mixing particles of a metal such as tungsten stainless steel or particles of a ceramic into a resin such as nylon or other suitable material the specific gravity can be optionally set up to about 15 depending on the kind of resin and the combination of mixed materials according to the vibrator support structure used in the vibrator portion 1 since a material having a specific gravity of about 3 0 or greater as a material for the vibrator base 5 is used the weight of the vibrator base 5 can be made large this allows the vibrator base to be miniaturized and consequently downsizing of the vibrating gyroscope to be achieved in addition since the vibrator support structure can be produced by injection molding with the metal or ceramic particles mixed therein as well as in the case where a metal or a ceramic is not mixed the increase in the production cost thereof can be prevented as compared with conventional vibrator bases having the same size as the vibrator base according to preferred embodiments of the present invention the vibrator base according to preferred embodiments of the present invention has a large weight so that its.
