Claim:
A brush seal device in which splitting surfaces of a plurality of split-body parts are combined with one another and which is mounted to one of opposed component members so as to seal a gap between said component members, comprising: a brush seal formed in a wall shape in the longitudinal direction of a fixture portion which is fixed at one end thereof; said split-body parts which hold said brush seal and each of which has connecting portions that are split and that extend along said splitting surfaces, wherein each of said splitting surfaces is composed of splitting direction-extending surfaces that extend in such a direction as to split said split-body parts and a longitudinal surface that extends in the longitudinal direction of said split-body parts and that forms a step interposed between said splitting direction-extending surfaces, wherein said splitting surfaces are formed at different circumferential positions on both axial sides of the brush seal, and wherein each of said splitting direction-extending surfaces has shutoff means for sealing a gap between said splitting direction-extending surfaces that are combined with each other.
