Abstract: PROBLEM TO BE SOLVED: To reduce the burden on the hip when a user sleeps on the back, and soften the pressure to the vicinity of the anus and the burden on the hip when the user sits on a chair or the like. SOLUTION: A small cushion (5) is attached to a belt main body (1) which is fitted to the hip and the thighs, and the buttocks are slightly pressed and the belly is slightly bent when the user sleeps on the back. By this constitution, the burden applied to the belly section caused by an S-shape state of the spine is softened because the spine is prevented from warping. Also, when the user sleeps on the side, the user can sleep in the same state as without the apparatus. Then, the location of the small cushion (5) which is attached to the belt (1) fitted on the hip and the thighs is adjusted, and the vicinity of the anus is lifted when the user sits. By this constitution, a pressure to the vicinity of the anus is reduced, and the burden is softened.  Also, the buttocks become higher than the thighs, and the user can sit while slightly tilting the hip, and the burden on the hip can be reduced.
