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.

摘要： An airtightness maintaining structure for a butterfly valve includes a valve element having a rotating shaft and a valve body, a rotation supporting portion having a pivotably supporting member that fits onto the rotating shaft and pivotably supports the rotating shaft, and a rotating shaft seal arranged to contact in a fitting state both an end surface of a member on an outer radial and a surface of a member on an inner side either the rotation shaft or the pivotably supporting member and has an annular portion. In a closed valve state of the valve element, the rotating shaft seal moves radially due to a pressure difference between a high fluid pressure acting on one side of the valve element and a low fluid pressure acting on the other side and contacts both the valve element and the rotation supporting portion on the high fluid pressure side.
