Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an engine air-intake controller capable of greatly reducing power which switches valve plates and holds them at preset switching positions. SOLUTION: In the engine air-intake controller, the valve plate 15 comprises first and second valve plates 15a and 15b disposed in a butterfly manner and extending oppositely from the valve shaft 14. In the first switching position A of the valve plate 15, the first valve plate 15a is oriented to the downstream side of the long air-intake path 4 from the valve shaft 14 and the second valve plate 15b is oriented to the upstream side of the long air intake path 4 from the valve shaft 14 to form one part of the long air-intake path 4 by one plate surface F1 of the valve plate 15. Similarly, in the second switching position B of the valve plate 15, the first valve plate 15a is oriented to the downstream side of the short air intake path 5 from the valve shaft 14 and the second valve plate 15b is oriented to the upstream side of the short air intake path 5 from the valve shaft 14 to form one part of the short air intake path 5 by one plate surface F2 of the valve plate 15.
