An intake device for an internal combustion engine configures a flow passage for intake air that is drawn into combustion chambers. The intake device includes an intake manifold configuring multiple runners that respectively distribute intake air to multiple cylinders, a surge tank including a cavity that is connected to the runners and defines a convergence portion, a throttle body incorporating a throttle valve, and a connection pipe connecting the surge tank and the throttle body and configuring a curved flow passage extending between the throttle body and the surge tank. The connection pipe includes a partition plate that divides the curved flow passage into a circumferentially inner flow passage and a circumferentially outer flow passage.

The present invention is provided with a configuration which makes it possible to inhibit contact between an oil (L) and a gas in an oil pan () properly. The oil pan () according to the present invention contains a film (S) which covers an oil surface (F) of the oil (L) to separate the stored oil (L) and the gas above the oil (L). The film (S) can float by receiving buoyancy in the oil (L). The film (S) may be formed of a liquid. The film also may be configured by a film member.
