PURPOSE: To provide a vibration gyroscope having a supporting structure, which can prevent the leaking of the vibration from a vibrator, maintains the vibration absorbing effect without obstructing the vibration, and can prevent the deformation caused by excessive shock from the outside. CONSTITUTION: This gyroscope has a columnar vibrator 2, a driving means and a detecting means, which are provided on the side surface of the vibrator 2, supporting members 4, which are formed out of plate materials in an approximately frame shape and support the vicinities of the node points of the vibrator 2 at the inner peripheral part, a holding substrate 6, which has supporting pieces 9 on both sides of the vibrator 2 in the width direction, and linking parts 5 and 5 for linking the supporting members 4 and the supporting pieces 9 of the holding substrate 6. The linking parts 5 and 5 are located on a straight line, which passes the center of gravity of the cross section in the vicinity of the node point of the vibrator 2 and is orthogonal to the bending vibration direction of the vibrator 2. |
