Abstract
A primary technical goal of the present invention is to improve seal performance of a brush seal and to provide flexibility for preventing wear of the brush seal due to friction. The sheet brush seal disk comprises a first halved brush seal disk and a mating second halved brush seal disk wherein a pair of the first base portion of the first halved brush seal disk and the second base portion of the second halved brush seal disk are stacked with each other. In the brush portion of the sheet brush seal disk, the convex first brush portion and the concave first slit portion disposed in the first halved brush seal disk engage the convex second brush portion and the concave second slit portion disposed in the second halved brush seal disk, respectively.
