The present invention relates to a spine adjuster structure, which comprises a first body, and the first body is formed as a whole and in a long strip body shape. The first body has a suitable length approximately equal to the length of human spine. The first body is about the length of the upper human body. One end of the first body is configured with a first arc-shaped surface and the other end is configured with a second arc-shaped surface, in which the first arc-shaped surface is provided for the hip to lean on and the second arc-shaped surface is provided for the head to lean on. The first body is configured with a first arc-shaped portion extended from one end of the first body to the other end and followed the curvature of human spine. The first body is configured with a second arc-shaped portion which is extended from one side of the first body to the other side and is formed in a lateral direction perpendicular to the first arc-shaped portion.本發明係關於一種脊椎調整器結構,其係包括:一第一本體,該第一本體係為一體成型狀,該第一本體係為一長條體狀,該第一本體係具有一適當長度,該第一本體係略等於人體脊椎之長度,該第一本體係略等於人體上半身之長度,該第一本體一端係設有第一弧面,該第一本體另端係設有第二弧面;該第一弧面係供臀部靠抵,該第二弧面係供頭部靠抵,該第一本體係設有一第一弧部,該第一弧部係延著第一本體一端至另一端,該第一弧部係配合人體之脊椎弧度;該第一本體係設有第二弧部,該第二弧部係延著第一本體一側至另一側,該第二弧部係呈橫向狀,該第二弧部與第一弧部係呈相互垂直狀。10‧‧‧第一本體11‧‧‧第一溝槽12‧‧‧第一弧面13‧‧‧第二弧面14‧‧‧第一容槽15‧‧‧透空槽20‧‧‧作用件
