Abstract

PURPOSE: To prevent the change in acceleration of case by specifying the shape of a recess containing an acceleration sensing spherical body.
CONSTITUTION: A recess 2 which becomes a concave portion 3 whose diameter is circular and whose bottom consists of a concave curved face is formed in a case 1. In the concave portion 3, the angle θ that a plane 5 and horizontal plane 7 assume is gradually increased as it goes toward opening edge 3a from the bottom part. In addition, the angle that the plane 8 of the upper concave portion 4 assumes to the horizontal plane 7 is made constant. Further, the radius of the acceleration sensing spherical body 9 contained in the recess 2 is made smaller than the radius of curvature of the concave portion 3. Then, when the case 1 is accelerated or decelerated in the direction perpendicular to the central axis 6, the spherical body 9 rolls and ascends the inside surface of the recess 2 and when the acceleration or deceleration exceeds a fixed value, said body presses a pressure detecting element 10. since there are no ridge angle parts in the recess 2, the recess 2 does not wear and break despite the collision with the spherical body 9, hence the change in the acceleration of the case 1 is prevented.
