<p><P>PROBLEM TO BE SOLVED: To enhance vibration absorbing effect to a throttle valve device connected to a throttle-side flange by the rigidity of a head-side flange itself and the connection of the head-side flange to a cylinder head by a fixation means in an intake manifold having a divided structure. <P>SOLUTION: The intake manifold M comprises two or more split bodies P1 to P3. The throttle-side flange 22 in which the throttle valve device 4 is connected, and the head-side flange 40 connected to the cylinder head 2, where air intake ports 5 is provided, are integrally formed with the first split body P1 out of the two or more split bodies P1 to P3. An inlet section 21 is integrally formed with the first split body P1. The inlet section 21 forms at least a part of an inlet path 11 of an intake passage 10 and has the flange 22. The flange 40 has an extension section 42 integrally formed with the inlet section 21 and extending in the direction intersecting with the inlet path 11. A pair of bolts 45<SB>1</SB>, 45<SB>2</SB>for connecting the flange 40 to the cylinder head 2 are arranged with the inlet path 11 interposed therebetween. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
