Beschreibung
Zusammenfassung:	An air intake device includes a bypass passage which makes a portion of an air intake passage on an upstream side of a compressor and a portion of the air intake passage on a downstream side of the compressor communicate with each other, and a bypass passage open/close valve which opens or closes the bypass passage. The air intake passage includes a first passage extending toward an upstream side from the compressor along a first direction, a bent portion bent from an upstream end of the first passage in a second direction, and a second passage extending from an upstream end of the bent portion along the second direction. The second passage has a vertically elongated cross-sectional shape. A vibration suppressing part for suppressing vibrations of the second passage is disposed in at least one of the second passage and the bent portion.
