Abstract: An intake air flow control valve comprises a metal shaft having a noncircular cross sectional shape; and a valve element fixed to the metal shaft and arranged to close and open a cross section of the intake passage with rotation of the metal shaft. The valve element is an integral unit including a resin part of resin material and a metal part of metallic material. The resin part includes an intermediate portion formed with a shaft receiving groove in which the noncircular metal shaft is fit. The metal part extends along the shaft receiving groove, and includes a wide section to regulate fluid flow.

Abstract: An air intake system for an internal combustion engine has a valve body that can open/close a passage cross section of a part of an air intake passage; a rotation shaft that extends to both sides of the valve body and supports rotation of the valve body; a valve accommodating recess that is formed on an inner wall surface of the air intake passage and accommodates therein the valve body; and a protruding line that is formed on an outer peripheral side surface of the valve body, which faces the valve accommodating recess, and extends along a shaft direction of the rotation shaft. The air intake system further has a communication passage that directly connects the valve accommodating recess and an intake port of the internal combustion engine.
