Intake apparatus for internal combustion engine

An intake apparatus for an internal combustion engine, including a partition (11) extending in a longitudinal direction of an intake port (5) so as to divide an inside region of the intake port (5) into a first passage (5A) and a second passage (5B), and a gas motion control valve (31) disposed at a downstream end of an intake manifold and adjacent to an upstream end of the partition (11). The gas motion control valve includes a rotatable valve element (33) and has a full-closed position where the valve element fully closes the second passage (5B) of the intake port and a full-open position where the valve element fully opens the second passage (5B) of the intake port. The valve element and the partition cooperate with each other to define an interspace (12) between the valve element (33) and the upstream end of the partition (11) when the gas motion control valve (31) is in the full-closed position.
