摘要： An inner wall surface of a low-pressure-side side plate opposite to a lateral surface of a thin plats is formed along a direction crossing an axial direction of a rotating shaft such that a gap between the inner wall surface and the thin plate gradually decreases from a radially inner side toward a radially outer side of the low-pressure-side side plate.
