Since the fixing member 5 has a long length in the circumferential direction, the shear stress per unit length in the circumferential direction based on the shearing force acting on the fixing member 5 is small. Therefore, the fixing member 5 may be short in the radial direction, and the brush seal 1 can be configured compactly.
- the opening of the space 6 formed by the concave groove 24 and the concave groove 35 is the circumference of the low-pressure side plate 2 and the high-pressure side plate 3.

- a hooking portion in the radial direction is formed between the rib 23 and the rib 34, and movement in the radial direction is restricted, so that the assembly of the high-pressure side plate 3 with respect to the low-pressure side plate 2 is excellent.
- the fixing member 5 is disposed in the space 6 in the circumferential direction. 2, 3 can be firmly fixed.
- a plurality of fixing members 5A1, 5A2, 5A1, 5A2, 5A1, 5A2 may be arranged in one space 6.

Fixing is further ensured by spot welding a portion 50 ′ where the three members 5, 5 A 1, 5 A 2, 5 B 1, 5 B 2, the low pressure side plate 2 and the high pressure side plate 3 abut.
- the high pressure side plate 3 is assembled from the axial direction after the brush body 4 is assembled to the low pressure side plate 2 has been described, but the high pressure side plate 3 is rotated in the circumferential direction. It may be assembled. Further, the assembly order may be the order in which the low pressure side plate 3 is assembled after the brush body 4 is assembled to the high pressure side plate 3.
