Beschreibung
Zusammenfassung:	[Task] To cause the individual cylinders to evenly suck the water produced by the melting of icicles when the ceiling surface of the surge tank is inclined with respect to the engine output shaft.[Solution] In the intake passage structure of an engine E that has a plurality of cylinders and an engine output shaft Ac disposed in the vehicle front and rear direction, the engine E is mounted on an automobile 100 in the state in which the engine output shaft Ac is inclined downward toward the vehicle rear side. An intake device 2 with the intake passage structure includes a surge tank 8 attached to an entrance portion 11a of an intake port 11 formed in a cylinder head 1b of the engine E, in which a ceiling surface 81a of the inner peripheral surface of a surge tank 8 is inclined downward along the engine output shaft Ac, and a first projecting portion 84 extending in the intake and exhaust direction of the engine E and projecting toward a bottom surface 82a of the inner peripheral surface of the surge tank 8 is formed on the ceiling surface 81a.
