PURPOSE:To improve safety in time of having a drive, by causing an engine to be stopped when detecting that a car reaches above the limited speed by means of a warning lamp tachometer as well as when detecting that a driver is in a state of intoxication by means of a gas detector. CONSTITUTION:When a set switch 3 is turned on, and operating relay circuit 8 gets excited, a switch 10 of an igniter circuit is closed, whereby the ignition device comes into a state of operation. That is to say, a high voltage produced at an ignition coil 14 by action of a contact breaker 15 is fed to an ignition plug 17 and thereby the engine is started. In this driving condition, if the running speed reaches above the limited one, a gap between a fixed contact 7 to be set manually and a movable contact 6 of a tachometer is closed. Likewise when centrifugal force at the time of running curves grows too large, a curve safety switch 36 is closed as well. In addition, if a driver is in a state of intoxication, the contact of a gas detector 38 is as well closed. Then, each detecting device as mentioned above gets into a state of either of the operations, the operating relay 8 is de-energized so that the engine comes to a stop. |
