PROBLEM TO BE SOLVED: To provide a massage machine which makes the body of a user three-dimensionally stretch or twist by utilizing an expansion/contraction bag to be expanded and contracted by an air supply/discharge device and increases density in a body treating part to which the effect of the stretch or the twist is exerted.SOLUTION: In the massage machine 1a, the expansion/contraction bags 2a which are pressurized and expanded and contracted or pressurized and kept expanded by the supply/discharge of air by the air supply/discharge device 3a are disposed inside the appropriate part of a chair main body 10a comprising a seat part 11a and a backrest part 12a connected at the rear part of the seat part 11a so as to be raised and brought down. A pair of left and right expansion/contraction bags 2a are provided respectively in the seat part 11a and the backrest part 12a, and when the backrest part 12a is raised, only one side of the pair of left and right expansion/contraction bags 2a in the seat part 11a is expanded and only the expansion/contraction bag 2a on the side opposite to the expansion/contraction bag 2a expanded in the seat part 11a between the pair of left and right expansion/contraction bags 2a in the backrest part 12a is expanded.COPYRIGHT: (C)2009,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、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と該座部11a後部で起倒可能に連結する背凭れ部12aとからなる椅子本体10a適所に、空気給排装置3aによる空気の給排気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に左右一対としてそれぞれ設けると共に、背凭れ部12aの起立状態において座部11aの左右一対からなる膨縮袋2aのうち片側のみを膨張させると同時に、背凭れ部12aの左右一対からなる膨縮袋2aのうち座部11aで膨張させた膨縮袋2aとは左右反対側の膨縮袋2aのみを膨張させるよう構成した。【選択図】 図1
