PROBLEM TO BE SOLVED: To provide a girdle in which, regardless of standing position or sitting position, a tightening force is the biggest in a lower abdomen and is gradually reduced upward, so as to have a pressure distribution similar to the abdominal pressure.SOLUTION: The girdle has a part made of a stretchable elastic material at the center of a cloth having a roughly inverted triangle shape, and is put on by pulling the three vertexes from the waist and crotch part toward the back. The right and left oblique lines of the cloth are formed in a form of a pair of parabolic shapes facing each other with the vicinity of the lower end of the lower abdomen as the vertex, and the stretch part of the center is formed in a hyperbolic shape expanding upwards. A component of the force for pulling the cloth to the right and left is dissipated in the stretch part, and a tension distribution gradually decreasing from the lower side to the upper side is generated on the cloth on the abdominal part, so as to generate a distribution of the abdominal pressure gradually decreased upward according to the curvature of the abdominal part. |
