Claims

[Claims for Utility Model Registration] In an intake manifold in which a pair of adjacent intake passages are each formed by a separate area and a common area, the common area includes this common area. An intake manifold, characterized in that variable partition plates capable of dividing the regions into extensions of the pair of individual regions are provided in a timely manner. 2. An actuator is attached to the variable partition plate, and a control means connected to the actuator slides the variable partition plate between a position where it can be separated and a position where it is removed from the position where it can be separated, depending on the engine operating state. The intake manifold according to claim 1 of the utility model registration claim.
