PROBLEM TO BE SOLVED: To provide a massage machine with a high density in a body massaging part to extend body stretching or twisting effects for a user to three-dimensionally stretch or twist the body by using expansion/contraction bags to be expanded or contracted by an air feeding/discharging device.SOLUTION: The massage machine 1a includes expansion/contraction bags 2a to be pressed to be contracted or expanded and held by feeding/discharging air by the air feeding/discharging device 3a. The expansion/contraction bags 2a are housed at appropriate positions in a chair body 10a composed of a seat 11a and a backrest 12a reclinably connected to the rear of the seat 11a. The expansion/contraction bags 2a are disposed in pairs of right and left bags in the seat 11a and the backrest 12a respectively. Only one of the right and left expansion/contraction bags 2a on the seat 11a is expanded when the backrest 12a is raised. At the same time, only one expansion/contraction bag 2a on the opposite side from the bag 2a expanded on the seat 11a is expanded of a pair of right and left expansion/contraction bags 2a on the backrest 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、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
