Abstract
When a clearance between a rotor and the free end of a brush seal of thin plates becomes larger by oscillation of the rotor or the like, the enlarged clearance is effectively sealed. In order to achieve this effect, in a brush seal device, brush seal units as recess layers and brush seal units as projection layers are stacked in the direction of the pressure of the sealed fluid to form recess and projection portion on its free end. The inner diameter of the recess layer is different from that of the projection layer.
