Further, according to the present invention, since the operating lever has the base and the operating portion, after adjusting the angular position of the yaw rate sensor, the operating portion is detached from the base so that a hand or an object hits the operating lever. This prevents the angular position of the yaw rate sensor from being displaced.

Further, according to the present invention, since the operation section is detached from the base and attached to the opening, it is possible to prevent dust and the like from entering the housing through the opening. In addition, it is possible to prevent the operation unit from being lost.

Further, according to the present invention, since the operating lever and the yaw rate sensor are connected via the connecting means, even if the yaw rate sensor is disposed at a position separated from the front wall, the angular position of the yaw rate sensor is adjusted. can do.

According to the present invention, the yaw rate sensor can be mounted at a predetermined angle by the adjusting operation means, the angular position fixing means, and the display means. The angle position of the yaw rate sensor can be adjusted in advance to an angle position where the angular velocity detection surface is horizontal.

Further, according to the present invention, since the operation fixing member functions as the adjusting operation means and the angle position fixing means, the structure is simplified and the manufacturing procedure is simplified.
