PROBLEM TO BE SOLVED: To make a proper operation possible by detecting acceleration acting on a car body even if an attached posture is altered to a vehicle. SOLUTION: A bracket 28 where an inertia body 30 to inertia-move according to acceleration acting on a vehicle is arranged is rotatably supported in a housing, and even if the housing is varied in attaching angle to a car body, a weight 26 functions to make the bracket 28 take a fixed posture about a rotary shaft center, and the bracket 28 rotates, and an inertia body 30 is moved by its dead weight, and pawls 32, 34 are driven, and a braking means therefore rotatably releases the bracket 28. When the bracket 28 retuns to a vertical state by the functions of the weight 26, a braking means checks the rotary motion of the bracket 28 in relation to the motions of the pawls 32, 34 and is set in a state where it actuates in the case of the car body wholly inclined at a fixed angle. |
