However, the device section of the above-mentioned conventional general-purpose massage machine electrically or mechanically transmits the rotation of the motor to the kneading tool, and imparts various types of kneading motion to the kneading tool. Since it is configured as described above, the generation of noise from the driving unit and the operating unit is inevitable during use, and the mechanism becomes complicated with the increase in the number of types of operation of the massaging tool, not only increases the manufacturing cost,
Since the flexibility of the kneading action on the body depends on the elasticity of the kneading tool itself, there is an inconvenience that it is difficult to obtain a soft kneading pressure that can be obtained by a human hand.

Recently, for example, Japanese Patent Application Laid-Open
As can be seen in Japanese Patent No. 124210, an air bag (air cell) is attached to the contact surface of the human body of the chair type massage machine, and the air cell is inflated, expanded and contracted by supplying and discharging air into the air cell, and the air cushion acts. There has been proposed a massage machine adapted to perform shiatsu massage. Such a massage machine has the advantages that it can operate very quietly without noise because the massaging device is operated by air pressure, and that a soft massage can be obtained.

[0005] However, like the above-mentioned conventional general-purpose massage machine, a massage is performed in which the massage device is continuously moved up and down to roll or roll while rubbing from the neck to the waist of the body. In addition, the massage device cannot be stopped at a desired position to perform a selected massaging operation such as massaging, tapping, and acupressure, and there is a problem that the variety of massaging functions is poor.

The present invention makes use of the advantages of the air cell described above and further enhances the characteristics of the conventional general-purpose massage machine, which reduces noise, has a soft kneading pressure, and eliminates shoulder stiffness. An object of the present invention is to provide a massage device capable of providing an effective massage to a shoulder in response to a request.
