ABSTRACT:
A throttle controller has a first detecting device for outputting a signal corresponding to an amount of the accelerator operation of an accelerator operating mechanism; a second detecting device for outputting a signal corresponding to an opening of a throttle valve; a first controlling device for permitting drive control by a drive controlling device in such a manner that a clutch device separates a throttle opening and closing device from a driving device, when an output signal of the first detecting device is a signal representative of an amount of operation not more than a predetermined amount of accelerator operation and when an output signal of the second detecting means is a signal representative of an opening exceeding a predetermined throttle opening; and a second controlling device disposed in parallel with and independently of the first controlling device and adapted to permit control of the driving of the clutch device by the drive controlling device, the second controlling device permitting control of the driving of the clutch device by the drive controlling device in such a manner that the clutch device connects the throttle opening and closing device and the driving device, when an output signal of the first detecting device is a signal representative of an amount of operation not more than the predetermined amount of accelerator operation and when an output signal of the second detecting device is a signal representative of an opening exceeding the predetermined throttle opening.
