<p><P>PROBLEM TO BE SOLVED: To provide a flexible spherical object which is a hollow deformable spherical object or a spheroid, and to provide a self-sealing type flexible seal which can adhere flexibly and tightly to the inner wall of a tube flexibly even if the inner diameter of the tube changes or an in-tube movable body provided with the self-sealing type flexible seal. <P>SOLUTION: In the hollow ball-shaped round body, a part surrounded by a line connecting, through a land surface, the following four points, N1 point having a coordinate of np degree north latitude, 0 degree east longitude, S1 point having a coordinate of sp degree south latitude, m degree east longitude, N2 point having a coordinate of np degree north latitude, (360/n+a) degree east longitude, and S2 point having a coordinate of sp degree south latitude, (m+360/n+a) degree east longitude is cut off to form a spherical element. Spherical elements of n pieces are arranged on display in an east-west direction along the equator at 360/n degree interval to constitute a flexible spherical object. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
