Abstract

PURPOSE:To measure acceleration at car crash, by a method wherein a plumb to detect acceleration of vehicles is movably assembled to a coil spring in cantilever support, and the plumb of prescribed weight is assembled to the case simply and accurately. CONSTITUTION:At bottom center of a case 10 is fixed a bush 21 to which one end of a coil spring 20 of piano wire is secured. A circular plumb 30 is enclosed within the case 10 and movable in radial direction, and the spring 20 passes through a minimum inner diameter port 32 of a tapered hole 31 of the plumb 30 and slightly projects upwards. When impact inertia is applied to the plumb 30, the spring 20 is smoothly curved corresponding to movement of the plumb 30 and scratch trace representing acceleration at car crash is indicated by a recording instrument 33 disposed integrally with the plumb 30. Thus the plumb 30 of prescribed weight is assembled in the case 10 simply and accurately thereby acceleration at car crash is recorded.
