To enable to concentrate and distribute a desired pressure strength by reciprocating a massaging device in the right and left directions with the top and bottom contact parts are contacted or separated.

For example, to perform a stronger massaging, a massaging finger driving motor of massaging devices 10 and 11 are actuated and top and bottom contact parts 70, 70 are contacted. With this condition, an approach/ separate motor is rotated in the normal/reverse directions. This approaches/ separates the massaging devices 10 and 11 in the right and left directions to perform a strong massage in the horizontal direction. With the top and bottom contact parts 70, 70 contacted. a chain driving motor is rotated in the normal/ reverse directions, the massaging devices 10 and 11 are moved up and down along the guide rail, and this makes a strong stretching. With the top and bottom contact parts 70, 70 separated. by the same operation as described above, a weak massage is obtained.
