Abstract
A valve device has a valve that opens and closes a passage, and a cantilever bearing member rotatably supporting a rotating shaft of the valve. The cantilever bearing member has rolling-element bearings arranged in series in an axial direction of the rotating shaft. One of the rolling-element bearings located the closest to the passage has a rolling element, an inner race, an outer race and a seal portion. A space is defined between the inner race and the outer race to receive the rolling element. The seal portion made of rubber tightly seals the space on a side adjacent to the passage.
