<p>PROBLEM TO BE SOLVED: To adjust a center position of a curve of a curve bottom at a position of a bending part of a body which differs per user, by providing the mechanism with a means for adjusting the curved position. SOLUTION: On the under surface side from a knee bottom 13a to a leg bottom 13b, a first and a second connecting members 16, 17 are connected bendably to each other and installed movably along the under surface side, such that when bottoms 13 are displaced, the first and the second connecting members 16, 17 are displaced together to support a curve bottom 14, and a connecting position 18 of the first and the second connecting member 16, 17 is moved by sliding the first and the second connecting members 16, 17 along the under surface of the bottoms 13, so as to adjust the center position of the curve of the curve bottom 14.</p> |
