PURPOSE:To simplify structure, improve assembly performance, facilitate adjustment. CONSTITUTION:A strain sensor 10 and an accelerating direction detecting sensor 20 are installed on a body 2 having a recessed part 3. A pole 5 which moves when the acceleration is applied and takes out the information related to the magnitude and direction of the acceleration at the same time from the sensors 10 and 20 is accommodated into the recessed part. When the acceleration is applied onto the pole, a substrate 11 is pushed up and deformed, and the strain at this time is converted to an electric signal and taken out, and the magnitude of the acceleration is detected, and any contactor 4a of a plurality of contact points 4 for detecting direction which are installed in the prescribed angular intervals on the inside of the recessed part is pushed downward to contact a resistance film 23, and the voltage value corresponding to the resistance value variation between terminals is taken out from the contact position, and the direction of the acceleration is detected from the relation between the voltage value and direction. |
