<p><P>PROBLEM TO BE SOLVED: To improve intake efficiency by preventing a flow of intake air from being blocked with a valve element, when the valve element is disposed to the intake passage of an intake manifold. <P>SOLUTION: The valve gear of the intake manifold includes: the valve element 42 disposed to the intake passage R of the intake manifold; and a support body 44 rotatably supporting the valve element 42. Rotation of the valve element 42 switches a position restricting the intake passage R and a position releasing the intake passage R. The valve element 42 at a position releasing the intake passage R is stored in the support body 44 to prevent the block of the intake air flow by the valve element 42. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
