PROBLEM TO BE SOLVED: To provide a massage machine increasing density at a body treated part which a stretching or twisting effect reaches by three-dimensionally stretching or twisting a users body, by making use of utilizing expansion/contraction bags expanded and contracted by an air supply/exhaust device.SOLUTION: A massage machine 1a is mounted with expansion/contraction bags 2a pressure-expanded/contracted or pressure-expanded and held by an air supply/exhaust device 3a, in suitable parts of a chair body 10a including a seat part 11a and a backrest part 12a. A plurality of expansion/contraction bags 2a are juxtaposed in a lateral width direction at the seat part 11a and the backrest part 12a. Synchronous expansion/contraction bag row groups 20a are formed to synchronously expand/contract the expansion/contraction bags 2a in the seat part 11a and the expansion/contraction bags 2a in the backrest part 12a, adjacent to each other in the length direction of the chair body 10a between the seat part 11a and the backrest part 12a, and the respective synchronous expansion/contraction bag row groups 20a are sequentially expanded/contracted in the lateral width direction in the rising state of the backrest part 12a.COPYRIGHT: (C)2013,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
