PURPOSE: To improve restartability of an engine, in the captioned device automatically stopping and starting the engine in accordance with its operational state, by constituting the engine such that an automatically stopping function is cut when temperature of cooling water is out of a prescribed range.
CONSTITUTION: To obtain information for inhibiting a function of automatically stopping and starting an engine, an engine speed detector circuit 11 and clutch upper switch 1 or other detectors 2W10 are provided, and their output signals are input to an electronic controller 12. This controller 12 decides an inhibiting condition of automatic stop whether generated or not, here a cut of fuel and the like are inhibited by an automatic inhibition command S1. Here a thermosensor 5 of the above described detectors is used with such a sensor that a characteristic is provided to turn ON for cooling water temperature of the engine at, for instance, not higher than 75° and not lower than 105°, and an automatically stopping function of the engine can be cut even in case of the cooling water temperature in at least a range of high temperature and not higher than a prescribed low temperature range.
