PROBLEM TO BE SOLVED: To swiftly terminate the hyperthermic treatment while locally applying hyperthermic stimulation in a chair type massage machine having a built-in treatment mechanism movable in the vertical direction in a backrest to apply treatment such as rubbing massage and tapping massage to the back of a treated person with treatment elements mounted at the distal ends of a pair of left and right treatment arms in the treatment mechanism by the oscillation of the treatment arms in the cross direction, forward/backward or in the vertical direction.SOLUTION: In this invention, the treatment elements 23, which are left projecting in a conventional massage machine, are retracted into the backrest part 25 as indicated in fig.(a) when treatment is not applied, and a sheet body to cover a storage space 25a formed in the backrest part 25 for the treatment mechanism 25, which is stretched over the surface 25f of the backrest part 25 in the conventional massage machine, is stretched to the depth from the surface 25f. The sheet body is formed of an exothermic body to generate heat at the time of the hyperthermic treatment. Accordingly, if the whole exothermic body generates heat, the hyperthermic treatment can be locally applied to treatment positions only where the treatment elements 23 are applied as indicated in fig.(b).COPYRIGHT: (C)2009,JPO&INPIT【課題】背もたれに上下方向に移動可能な施療機構を内蔵し、前記施療機構における左右一対の施療アームが、幅、前後、上下方向に揺動することで、その略先端に設けられた施療子が施療者の背中にモミ動作やタタキ動作等の施療を行う椅子式マッサージ機において、局所的な温熱刺激を与えつつ、温熱施療の終了を速やかに行うことができるようにする。【解決手段】従来は突出したままの施療子23を、本発明では、非施療時には(a)のように背もたれ部25内に後退させ、また前記背もたれ部25に施療機構25のために形成されている収納空間25aを覆うシート体を、従来は背もたれ部25の表面25f上に張架されていたのを、前記表面25fから奥まって張架するとともに、それを発熱体で形成して、温熱施療時に発熱させる。したがって、発熱体全体が発熱しても、(b)のように施療子23が当っている施療箇所だけ局所的に温熱刺激を行うことができる。【選択図】図8
