Abstract
An exhaust device for adjusting an exhaust gas cross sectional area of an exhaust passage in a combustion engine includes a valve body arranged in the exhaust passage communicating to an exhaust port of the combustion engine; a valve shaft fixed or integrally formed to the valve body and arranged so as to transverse the exhaust passage, the valve shaft changing the opening of the valve body by turning with the valve body about an axis of the valve shaft; a pair of bearing members for supporting rotatably the valve shaft at both ends thereof in a axial direction of the valve shaft; and a stopper arranged on the valve shaft so as to face an end face on the inward side of the exhaust passage of each bearing member in the axial direction. The stopper is restricted in the axial direction by the end face of each of the bearing members so that the valve body and the valve shaft do not move in the axial direction.
