Abstract
An air intake device for an engine is provided in which a bypass valve (V) is formed from a tubular valve chamber () having its interior opening on the upstream side of a bypass () and having an inner face with a metering hole () opening toward the downstream side of the bypass (), and a valve body () that is slidably but non-rotatably fitted into the valve chamber () and that opens and closes the metering hole (), wherein the valve chamber () and the metering hole () are formed in a bypass valve holder () provided so as to be connected to a throttle body (), and a dividing wall () that divides the metering hole () into a plurality of small metering holes () arranged in the peripheral direction of the valve chamber () is formed in the bypass valve holder () so as to be continuous with an inner peripheral face of the valve chamber (). This can prevent any hindrance to the closing movement of the valve body of the bypass valve even when a large metering hole is employed.
