Abstract
An eccentric valve has a drive mechanism, a drive force receiving part, a bearing for supporting a rotary shaft, and a return spring for generating a return spring force. During non-operation of the drive mechanism, the eccentric valve generates a separating-direction urging force to cause the rotary shaft to incline about the bearing serving as a fulcrum and urge the valve element in a direction away from the valve seat, the separating-direction urging force being a force caused by the return spring force. Either the valve element or the valve seat is provided with a sealing member to seal between the valve element and the valve seat during non-operation of the drive mechanism.
