The The present invention induration of muscle that occurs in the human body, the flexibility in pressing by its own weight load to provide acupressure instrument to be restored. An acupressure instrument consists of four of the protrusion 1-4 and six of the side portions 10 to 13 in the elastic body with left and right surface symmetry pair two of the hardness of the three pyramid-like, projecting portion 1 angle of height and sides 10-13 of the ~ 4 is made up of a curved surface 5-8 with different parts. Taking advantage of the difference of the protrusion 1-4 and the side portions 10 to 13, the restored sacroiliac joints and adapt to induration of buttock muscle, the induration of the flexibility of the muscle with a pressing to repeat the weight load in the supine position It causes.BACKGROUND 1【課題】人体に出現する筋の硬結を、自身の体重負荷による押圧で柔軟性を復元させる指圧器具を提供する。【解決手段】指圧器具は三角錐体様の左右面対称一対2個の硬度のある弾性体で四つの突出部1~4と六つの辺部10~13から成り、突出部1~4の高さや辺部10~13の角度は異なる部分を有する曲面5~8で構成される。この突出部1~4と辺部10~13の相違を生かして、仰臥位で仙腸関節部及び臀部の筋の硬結へ適合させ、体重負荷を反復する押圧で筋の硬結の柔軟性を復元させる。【選択図】図1
