Abstract

Disclosed herein is a sealing apparatus with a brush that effectively seals a space between a rotor portion and a casing, minimizes the vibration of a turbine, and improves electricity generating and durability of the rotor portion. The sealing apparatus with the brush, including: a sealing portion provided for a casing of a turbine to seal a flow of a fluid leaking between the casing and a rotating body rotated in the casing; a brush portion that is provided for the sealing portion and includes a plurality of bristles disposed to surround an outer circumference of the rotating body; a shock preventing portion disposed to be spaced in a predetermined interval from a front side of the brush portion so as to block a flow of the fluid flowing along the outer circumference of the rotating body; and a bristle plate that is provided to support a rear side of the brush portion and has a plurality of guide holes formed therethrough to be inclined upward toward the casing as it goes from an inflow direction to an outflow direction of the fluid.
