Abstract A condition regulating device for meters for measuring the quantity of motion which have a sensor including a pendulum for sensing vibrations, and components for transmitting the swinging of the pendulum to a display for displaying the swinging of the pendulum as a function of the quantity of motion. The device includes an externally threaded regulating shaft having both its ends rotatably supported on a frame, a movable member designed to be in engagement with the external thread of the shaft and reciprocate axially in association with the rotation of the shaft, a lower limit stopper for the pendulum, which is integral with the movable member, a buffer lever rotatably mounted on the frame, which is designed such that, when the acceleration acting upon the pendulum exceeds a certain value, it buffers the swinging of the pendulum and the other end secured to the other end of the buffer lever.
