摘要： The present invention is to ensure degrees of freedom of bristles toward upstream and prevent their flapping at the same time, while also increasing the rigidity of bristles in the direction of pressure difference between the high-pressure side and low-pressure side to reduce the wear of bristles. Provided is a brush seal having: a bristle part formed by multiple bristles attached to a stationary part between the stationary part and a rotational part that undergo relative motion by maintaining a space in between; and a back plate attached adjacent to the bristle part on its low-pressure side to restrict the movement of the bristle part, for the purpose of sealing the fluid flowing between the stationary part and rotational part; wherein such brush seal is characterized in that the bristle part formed by multiple bristles is such that the multiple bristles arranged in the flowing direction of fluid are mutually fixed between the base end and free end to form planar bristles and these planar bristles are arranged continuously in layers in a circumferential direction to form the bristle part.
