PROBLEM TO BE SOLVED: To reduce a center pitch of adjacent throttle bodies by disposing a nut threaded to other side of a driving drum and to other end of a throttle value stem in a concave portion having a bottom provided on the other side surface of the driving drum in a multiple throttle bodies in which a plurality of single throttle bodies are laterally disposed. SOLUTION: In a device in which one side end T1a of a throttle body T1 and the other side end T2b of a throttle body T2 are disposed opposed to each other, respective throttle valve stems 2A, 2C are coaxially disposed at a slight space S at opposed ends. A driving drum 9 is disposed on an engaging step portion 2D of the throttle valve stem 2C. The driving drum 9 is tightened using a nut N disposed in a concave portion 9H having a bottom on the dege surface thereof. A bent portion 7A of a driven lever 7 and a bent portion 9C of a driving lever 9 are disposed opposed to each other and both levers 7, 9 are interlocked by penetrating a screw member 10 screwed into a female screw 7B of the bent portion 7A through a screw-inserting groove 9D of the driven lever 7 and tightening the screw member 10.
