Abstract

A brush seal device of the present invention has a holding portion and a brush having a plurality of bristles. The holding portion is held by one part and is in the shape of a sealing plate. One end portion of the brush is connected with the holding portion. A free end portion of the brush is disposed in parallel with the holding portion and protrudes therefrom so as to seal a gap between itself and the other part to which the brush is opposed. An elastic portion holds the side of the free end portion of the brush in light touch with a holding surface of the holding portion. The elastic portion also performs a sealing function so as to prevent sealed fluid from entering the side of the mounting portion of the brush.
