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