Abstract

[Problem] To provide a flexible spherical body (20) having a hollow deformable spherical body or a rotating elliptical body. In addition, to provide a self-sealing flexible seal (20) that can closely adhere to the inner wall of a tube, even if the inner diameter thereof varies, or a body for moving inside a tube and which is equipped with the self-sealing flexible seal (20). [Solution] A hollow ball-shaped spherical body, with a point N1 having coordinates north latitude np degrees, and east longitude 0 degrees, a point S1 having the coordinates south latitude sp degrees and east longitude m degrees, a point N2 having the coordinates north latitude np degrees and east longitude (360/n+a) degrees, a point S2 having the coordinates south latitude sp degrees and east longitude (m + 360/n+a) degrees, with the part surrounded by lines linking the above four points after passing through the surface removed to form a spherical body element (21). n of the spherical body elements (21) are positioned at an interval of 360/n degrees in the east-west direction along the equator to form the flexible spherical body (20).
