摘要： The present air intake control valve includes a valve body and a seal portion being elastically deformable to seal between an inner wall surface of an air intake port and the valve body. The seal portion is formed in a bending configuration including a first hinge portion and a second hinge portion each serving as a supporting point upon elastic deformation of the seal portion. One of the first hinge portion and the second hinge portion is arranged at an upstream side of the air intake port and the other of the first hinge portion and the second hinge portion is arranged at a downstream side in a state where the valve body is at a closed position.
