PROBLEM TO BE SOLVED: To provide a lumbar traction machine having a simple structure and facilitating a users operation, being repeatedly operated and utilized, dispensing with a heavy facility such as a bed, having the reduced number of components and provided at low cost, having a user-friendly operation and allowing a user to operate it with a little burden.SOLUTION: The lumbar traction machine includes a movable plate 9 having a slide surface with steel balls on the backside, installed on an inside upper face of a frame plate 2, causes a user to place the lumber part on a recess formed on the upper face of the movable plate 9, and pulls the lumbar spine by the movable plate 9. The lumbar traction machine pulls a wire W using a movable lever 13 for rotationally turning, via the wire W fixed to the movable plate 9, a support 8 erected on the frame of the frame plate 2, as a lever, to move the movable plate 9 along with a user M in the direction of the lower extremities and pull the lumbar spine.COPYRIGHT: (C)2015,JPO&INPIT【課題】機構と利用者の操作が簡単で、繰り返し操作、稼働が可能で、且つ、ベッド等の加重装備を要せず、部品点数が少なく低コストで供し、利用者による操作が優しく、負担の少ない操作ができる腰椎牽引機を提供する。【解決手段】枠板2内部上面に裏面に鋼球付きの滑面を形成した可動板9を載置し、該可動板9上面に形成した凹部に利用者の腰部を載置して該可動板9で腰椎を牽引する腰椎牽引機であり、前記可動板9に固着したワイヤWを介して前記枠板2の枠に立設した支軸8を回動する可動レバー13を梃子としてワイヤWを引張り、前記可動板9を利用者M共々下肢方向に移動させて、腰椎を牽引する。【選択図】図6
