PROBLEM TO BE SOLVED: To provide a small-sized/light-weight apparatus excellent in user-friendliness, and allowing a user to correct posture by effectively correcting the distortion of the pelvis or the rib cage lower part to a bilateral symmetrical physical relationship while doing exercise.SOLUTION: A posture correction apparatus is mounted on the body in a manner of surrounding the outer periphery, and includes: two fastening belts and at least one among four compression parts of a coxal bone front compression part abutting on the front side of the right and left coxal bones, a coxal bone rear compression part abutting on the rear side of the right and left coxal bones, a rib cage front compression part abutting on the front side of the right and left rib cage lower parts, and a rib cage rear compression part abutting on the rear side of the right and left rib cage lower parts. The coxal bone front compression part includes an inclined plane of inducing the coxal bone from the front outside to the rear center, and the coxal bone rear compression part includes an inclined plane of inducing the coxal bone from the rear outside to the center. The rib cage F front compression part includes an inclined plane of inducing to a direction where the rib is expanded from the front side to the right and left sides, and the rib cage rear compression part includes an inclined plane of inducing so as to expand the front side of the rib to the right and left sides. Each of the parts can independently perform pressure adjustment to the body.COPYRIGHT: (C)2015,JPO&INPIT【課題】小型・軽量で使い勝手に優れ、運動をしながら骨盤や胸郭下部の歪みを効果的に左右対称な位置関係に矯正して姿勢を矯正できる器具を提供する。【解決手段】姿勢矯正器は、左右の寛骨の前側に当接する寛骨前部圧迫部、左右の寛骨の後側に当接する寛骨後部圧迫部、左右の胸郭下部の前側に当接する胸郭前部圧迫部、及び左右の胸郭下部の後側に当接する胸郭後部圧迫部の四つの圧迫部のうちの少なくとも一つ以上と、二本の締付ベルトとを備え、外周を包囲する態様で身体に装着される。寛骨前部圧迫部は寛骨を前方外側から後方中央へ誘導する傾斜面を備え、寛骨後部圧迫部は寛骨を後方外側から中央へ誘導する傾斜面を備え、胸郭F前部圧迫部は肋骨を前方から左右に拡張させる方向に誘導する傾斜面を備え、胸郭後部圧迫部は肋骨の前側が左右に拡張するように誘導する傾斜面を備え、それぞれ単独で身体への押圧調整ができる。【選択図】図3
