PURPOSE:To maintain a good performance of the automobile parts and to secure the safety by informing the necessity of the replacement of parts concerned with an alarm lasting for a fixed distance every time the car reaches a fixed running distance. CONSTITUTION:The rotating position detectors 11-13 are provided to the rotary drums 1-3 of the integrating running distance meter 8 equipped with the rotary drums 1-6 of multiple digits for indicating the distance. The rotating position detectors 11-13 detect whether the rotary drums 1-3 are in the fixed rotating angle positions. Whether the rotating position detectors 11-13 are in the fixed rotating angle positions is always monitored by the fixed running distance detector 14, when all the detectors 11-13 become the state of a fixed rotating angle position, the fact that a fixed distance is reached is decided, the fixed running distance detector 14 delivers an output signal to the alarm 15 to give a warning. |
