To sufficiently ensure the supporting rigidity while simplifying a structure of supporting an intake system module including a throttle body connection part and an intake manifold upstream part.
An engine air intake device has an intake system module 3 with the throttle body connection part and the intake manifold upstream part integrated with each other and an intake manifold downstream part 2 extended from an engine body 1. A downstream end of the intake system module 3 is connected to the intake manifold downstream part 2, and an end part opposite to this part is connected to an upper end part of an oil filler pipe 50 connected to the engine body 1, and thus, the intake system module is supported by the engine body 1 via the oil filler pipe 50.
