Throttle control device
 A throttle control device freely sets the throttle opening area changing ratio in the low opening degree range to the intermediate and high opening degree range. The throttle valve is rotatably supported to an air intake passage to vary the area of the air intake passage, and rotated by a throttle lever fixed to the throttle valve. A drive lever is rotated with stepping down of an accelerator pedal by the driver. A cam mechanism transmits rotation of the drive lever, to the throttle lever and a link mechanism having a connecting lever transmits rotation of the drive lever to the throttle lever. The cam mechanism and the link mechanism are switched to be operated corresponding to the opening degree of the throttle valve.
