Vibration gyroscope and electronic device using the same

摘要

A vibration gyroscope includes a vibrator base that supports a vibrator in a hollow portion of the base and includes a frame-shaped portion. Protrusion portions are provided on the inner wall of the frame-shaped portion which defines a stopper that restricts displacement of the vibrator beyond a desired distance. The frame-shaped portion and the protrusion portions are integrally formed by a two-color molding method to define a single unitary member.
