Abstract

See full text

A valve device includes: a seal member that is slidably in close contact with an outer peripheral surface of a rotation shaft; and an annular attachment ring that attaches the seal member to a housing. The seal member has a first-side plate part and a second-side plate part sandwiching and holding the seal member in an axial direction of the rotation shaft. An inner peripheral end of the second-side plate part is positioned radially outside beyond an inner peripheral end of the first-side plate part. An outer surface of the first-side plate part includes an outer peripheral-side region positioned radially outside beyond the inner peripheral end of the second-side plate part and an inner peripheral-side region positioned radially inside beyond the outer peripheral-side region. The outer peripheral-side region is positioned on a first side of the axial direction with respect to the inner peripheral-side region.
