PROBLEM TO BE SOLVED: To provide a massage machine which gives the body of a user a three dimensional stretch or twist utilizing an expanding and contracting bag which expands and contracts by an air supply and discharge device and increases density in a body treatment area which has the effect of the stretch or twist.SOLUTION: The massage machine 1a includes the expanding and contracting bag 2a which holds pressing expansion and contraction or pressing expansion by the air supply and discharge device 3a in the proper place of a chair body 10a which consists of a seat 11a and a backrest part 12a. While the plurality of expanding and contracting bags 2a are arranged in parallel in the horizontal width direction of the seat 11a and the backrest part 12a respectively, a synchronous expanding and contracting bag array 20a which synchronously expands, and contracts the expanding and contracting bag 2a of the seat 11a and the expanding and contracting bag 2a of the backrest part 12a, which neighbor each other in the length direction of the chair body 10a between the seat 11a and the backrest part 12a, is constituted. Each synchronous expanding and contracting bag array 20a is organized so that it expands and contracts sequentially in the horizontal width direction in the standing state of the backrest part 12a.COPYRIGHT: (C)2012,JPO&INPIT【課題】空気給排装置により膨張及び収縮する膨縮袋を活用して三次元的なストレッチまたはひねりを使用者の身体に行わせて、そのストレッチまたはひねりの効果が及ぶ身体施療部位における密度を高めたマッサージ機を提供する。【解決手段】座部11aと背凭れ部12aとからなる椅子本体10a適所に空気給排装置3aにより押圧膨縮または押圧膨張保持する膨縮袋2aを内装したマッサージ機1aであって、該膨縮袋2aを座部11a及び背凭れ部12aにそれぞれ左右幅方向において複数並設すると共に、座部11aと背凭れ部12aとの間における椅子本体10aの長さ方向においてそれぞれ相隣する座部11aの膨縮袋2aと背凭れ部12aの膨縮袋2aとを同期膨縮する同期膨縮袋列群20aを構成し、背凭れ部12aの起立状態において各同期膨縮袋列群20aを左右幅方向において順次膨縮するよう構成した。【選択図】 図18
