<p><P>PROBLEM TO BE SOLVED: To provide an intake control device for an engine capable of effectively transmitting driving force of an operation lever to a valve element, capable of reducing a load on an actuator, and capable of achieving miniaturization. <P>SOLUTION: The sleeve type valve element 8 moving between a close position A fitted to one of confronting end parts 3b and 4a of first and second intake passages 3 and 4 slidably along an axial direction and abutted to the other and an open position B separated from the other is provided, a trunnion 16 is protruded on an outer side surface of the valve element 8, the operation lever 19 having a groove 22 engaged with the trunnion 16 is connected to a lever shaft 18 supported by an intake manifold M, and the trunnion 16 and the lever shaft 18 are arranged on or near a plane L orthogonal to an opening and closing direction D of the valve element 8 when the valve element 8 is in the close position A or the open position B, and confronting inner side surfaces 22a and 22b of the groove 22 are arranged along a pair of planes J and K crossing with each other at or near an axis Y of the lever shaft 18 and holding an outer peripheral surface of the trunnion 16 between them. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
