PURPOSE: To easily and securely prevent zero-point drift caused by improper assembling attitude for a device concerning a device for detecting moving state that detects the state of vehicle, etc., moving toward the specified direction and its production method. CONSTITUTION: A pendulum 16 provided with a slit 16a on its lower end and a supporting member 18 provided with a photocoupler 18a at the position corresponding to the slit 16a are together fixed rotatably to a sensor housing 12 by using a supporting shaft 14 as a center. In order to assemble an acceleration detector 10 on a vehicle, first the housing 12 is fitted onto the vehicle body while the pendulum 16 and member 18 are rotatable. Next a fixing plate 20 provided with a fixing pin 20b for fixing the member 18 is fixed by a bolt together with the housing 12. |
