PROBLEM TO BE SOLVED: To provide a massage machine capable of stretching or twisting the body of a user three-dimensionally by using expandable/contractable bags that are expanded or contracted by means of an air supply/exhaust device, and capable of enhancing the stretching or twisting effect consistently on body regions to be treated.SOLUTION: In this massage machine 1a, the expandable/contractable bags 2a for retaining press-expansion or press-contraction by means of the air supply/exhaust device 3a are internally provided in suitable parts of a chair body 10a which includes a seat 11a and a backrest 12a reclinably connected to the rear part of the seat 11a. The expandable/contractable bags 2a are paired and symmetrically arranged respectively in the seat 11a and the backrest 12a. Also, only the expandable/contractable bags 2a on one side of the pair in the seat 11a are expanded when the backrest 12a is in an erected state, while, among the expandable/contractable bags 2a in the backrest 12a, only the expandable/contractable bags 2a on the opposite side of the expandable/contractable bags 2a expanded in the seat 11a are expanded.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、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
