<p>PURPOSE:To simplify structure, improve assembly performance and facilitate adjustment. CONSTITUTION:A ball 4 which moves along the inner surface when acceleration is applied is accommodated in a body 2 on which a recessed part 3 having the inner surface having an ascent slope towards the periphery from the center is formed. Further, a detecting lever 5 whose one edge is pivotally installed on the body and the intermediate part contacts the top part of the ball 4 is installed. A noncontact type sensor 6 such as magnetic resistance sensor and photosensor are arranged, positioned at the other edge of the detecting lever. When accelerating speed is applied, the ball moves along the inner surface of the recessed part, and the position of the ball changes upwardly. At this time, the detection lever in contact with the ball is pushed upward, and the displacement of the other edge of the detecting lever is sensed by the noncontact type sensor, and an electric signal is taken out.</p> |
