PURPOSE:To prevent a hazard in which a supply amount of fuel is increased to maximum when a trouble is caused in a controller, by providing a safety throttle valve independently of an electrically controlled fuel supply device and mechanically operating the safety throttle valve with an accelerator pedal. CONSTITUTION:A device is constitutes such that a stroke of an accelerator pedal 18 is detected by an accelerator pedal sensor 24, and this detection signal is supplied to an electronic controller 100 to control a throttle valve 8 through a throttle valve actuator 10. While a safety throttle valve 32 is provided to an intake pipe 4 and connected to the accelerator pedal 18 through a spring 28, wire, fixed part 34 and stopper 36. In this way, even if a trouble is caused in the accelerator pedal sensor 24, actuator 10, controller 100, etc., a hazard that the throttle valves 8, 32 are fully opened in no connection to an intention of the driver, can be prevented. |
