ABSTRACT:
A pendulum acceleration sensor includes a plate-like pendulum, at least a pair of detection sensors, and a holder unit. The pendulum swings about a shaft in a direction parallel to the side surfaces of the pendulum in accordance with an acceleration. The pair of detection sensors are arranged to oppose each other with the pendulum interposed therebetween to detect the displacement amount of the pendulum upon swing. The holder unit is constituted by sensor storing members for storing the detection sensors and positioning the detection sensors with respect to the pendulum, and shaft support members integrally formed with the sensor storing members to pivotally support two ends of the shaft of the pendulum and define a swing space for the pendulum.
