Abstract:
A brush seal of a brush seal device, mounted on one of two components that are relatively rotated, for sealing the clearance given between the two components, comprising:a plurality of the brush seal units, each having a strip-like brush section on a side facing the other component and having a base plate section on a side opposing the side having the brush section, the brush section being formed with thin beams each of which is between two slits, and the base plate section being fixed to the one component; and a plurality of positioning sections spaced at pitch intervals located in the base plate section of the brush seal unit; wherein the pitch intervals of the positioning sections are determined so that, by relatively displacing by one pitch the positioning sections of the neighboring brush seal units to be piled, the strip-like slits and thin beams can overlap each other, and wherein the brush seal unit has a plurality of divided modular plates, the modular plate has a connecting recess at its one end and a connecting projection at its other end, and the connecting recess and the connecting projection of neighboring modular plates are coupled each other.
