As a result, the pair of side plates 11, 11 screwed into the width drive shaft 5b in a reverse screw relationship move so as to approach each other. Along with this, the housing 9 and the eccentric inner ring 10 move in a direction in which they approach each other along the rubbing shaft 2b. This movement reduces the distance between the treatment elements 7a and 7b. In addition, the expansion of the interval between the massaging elements 7a and 7b is performed by rotating the width drive source 5a and the width shaft 5b in opposite directions, so that the housing 9 and the like move in a direction away from each other along the kneading shaft 2b. The interval between the treatment elements 7a and 7b is expanded. Each of the above operations is performed by inputting the switch 31 of the operation input device 21.

Next, the case where the position selection switch 26 of the operation input device 21, which is the main operation of the present invention, is input will be described. That is, when the massage part setting is input from the position selection switch 26 to the position control circuit 24, the position control circuit 24 detects the current positions of the treatment elements 7a and 7b from the outputs of the rotation angle detectors 22 and 25 and selects them. A movement command is input to the control circuit 20 so that the treatment elements 7a and 7b move to the designated portion. The treatment elements 7a and 7b are moved by this movement command, and the movement command is stopped when the selected part and the current position become equal. For example, as shown in FIG. 11, the rotation angle detectors 22 and 25, the position selection switch 2
When the present position is the width direction 1 and the vertical direction 5, and the positions of the width direction 2 and the vertical direction 0 are selected, the treatment elements 7a, 7 7
The width between b is widened and raised to move to the selected site.

Although the step motor is used as the power source in the above description of the operation, a linear step motor, a servo motor or the like may be used. Further, a touch panel using capacitance or the like may be used as the position selection switch 26.
