PURPOSE:To increase the degree of freedom of arrangement of respective air intake passages by tuning respective throttle valves with use of an electric signal in the captioned device in which the throttle valves each provided on the plural air intake passages are tuned with each other by means of a single operation body. CONSTITUTION:Applied the captioned device to a motor cycle, a rotation displacement of an operating body 50 operated by a driver is converted to an electric displacement signal through a transducer 42 and delivered to a control unit 40. An electric driving signal is issued from the same unit 40, and applied to servomotors 41, 41a connected with respective throttle valves 32, 32a of plural carburetors 30, 30a for their controlled rotation. Hereby, the respective throttle valves 32, 32a are tuned with each other, and displaced in rotation so as to reach an opening corresponding to a rotation displacement of the operating body 50. |
