To obtain massage efficiency having a different strength without giving uncomfortable feeling by controlling hardness of treating members corresponding with a massage process in a massage machine having the treating members for giving the massage efficiency to a human body.
Treating members 1 of which operation gives massage efficiency to a human body are constituted in such a way that hardness of the treating members is controlled according to a massage process. The treating members 1 control tensile stress by changing distorted conditions of a spring 17 caused by rotation of a motor 10. When an operation body 13 is drawn together with a slide shaft 12 and action supporting members 15 are actuated expanding by an operation of a slanted surface 14, a treating touch body 16 is pushed from an inside to change its hardness to a hard condition. The hardness of the treating members 1 is kept in a soft condition (soft) at early and final stages of the massage process, and the hardness is changed to a hard condition (hard), at a middle stage of the massage process.
