PROBLEM TO BE SOLVED: To easily perform the manufacture and the assembly at a low cost without using a link mechanism for an engine output from a power take-off unit, and capable of preventing a wrong operation due to mechanical vibration. SOLUTION: For this fire engine, an engine output for driving units 9 and 10 can be taken out to an engine 7 from the power take-off unit 8. The fire engine is equipped with a throttle control signal generating means 2 and an engine control unit 1. The signal generating means 2 generates the signal in response to a starting signal when the driving units 9 and 10 are started. The engine control unit 1 controls the engine revolution number by adjusting a throttle 71 in response to the voltage of the throttle control signal.
