PROBLEM TO BE SOLVED: To provide a vibration gyro which can prevent a rise in price although it has a stopper constitution for a vibrator, and an electronic device which uses the vibration gyro. SOLUTION: A vibrator base 2 which supports the vibrator 7 at its hollow part has a frame-shaped part 2a and projections 2c and 2d as stopper parts which are provided on the internal wall of the frame-shaped part 2a and limit the displacement of the vibrator exceeding a specific quantity; and the both are molded in one body by a dichroic integral molding method by using different materials. Consequently, the limitation of excessive displacement of the vibrator not only can prevent the plastic deformation of a support member and the breakage of the vibrator, but also can lower the cost by the reduction of the number of components. |
