Therefore, in order to improve the pressure received from daily life and to avoid the aftereffects, many people use their leisure time to release their mind and body from various pressures.
However, whether or not the effect of releasing the mind and body from the pressure can be effectively obtained by the massage depends on the arm of the engineer who performs the massage and also takes time. In general, the technical level of an engineer who performs massage is not constant. A prominent masseuse with excellent skills will have more patients and longer waiting times.
In view of the above situation, various massage machines have been developed.

A general massage machine is provided with a motor, and is provided with a massage part that is eccentric to the drive shaft of the motor. The feature is that the massage part is activated in synchronization with the motor, and is relative to each other. There is no movement or rotation of the position.
Therefore, in the structure of such a conventional massage machine, when the drive shaft of the motor rotates, the massage portion rotates with a bias with respect to the drive shaft. When the massage part is brought into contact with the part to be massaged, the massage part and the drive shaft of the motor do not move or rotate relative to each other, so a vibration force is generated by the reaction force generated, and the vibration force is used. And massage effect is obtained.

  As described above, when the massage part is brought into contact with the position where the human body is massaged, a massage effect is obtained by vibration due to local high-speed rotation. However, the vibration force generated from such eccentric high-speed rotation causes the massage to occur. Easily gives discomfort such as numbness and pain to the application position. For this reason, it is not possible to obtain comfort such as a massage by a human hand. Therefore, it is a challenge in this industry to develop a massage machine structure that can provide comfort close to the sensation of massage by human hands, efficiently relieve the user's body and relieve mental and physical fatigue. ing.
