A primary technical goal of this strip brush seal device is to prevent friction of a lifting portion (3B) of a seal portion (6) against the circumference of a rotary shaft (60) and to improve the seal capability thereof. In the strip brush seal device, each seal strip (3) in a seal portion (6) forms a stoppage portion (3A) in the radially outward portion thereof and a lifting strip (3B) in the radially inward portion thereof wherein the lifting strip (3B) is inflected toward the rotational direction of the rotary shaft (60) at a second angle (θ) to the tangential direction of the circumference of the rotary shaft (60) and the second angle (θ) is in the range of from 0 to 40 degrees.
