[Prior art]

 Many types of acupressure massagers of this type have been known so far, and for example, a large number of acupressure massagers built into the back of a chair have been developed. An acupressure massaging device built into the backrest usually has a pair of left and right acupressure devices consisting of an electric mechanism and a rotating roller built in up and down, and two pairs of up and down acupressure devices can be simultaneously moved up and down using the operation panel. It is configured to move and apply shiatsu to the back of a seated person. The strength of the acupressure is adjusted to be high, medium or low by the operation panel. In addition, many acupressure massage devices have been developed that are applied to automobile seats as well as household chairs.

As a built-in vehicle seat, for example, those described in Japanese Utility Model Publication No. 62-64530 and Japanese Utility Model Publication No. 5-82433 are known. The acupressure massager described in the former publication has two swinging rods that perform electric massage by a battery in two vertical grooves that are parallel to each other on the backrest portion of the seat with an appropriate space left and right. The position can be adjusted up and down. The acupressure massaging device described in the latter publication is provided with a plurality of massaging devices with vibrators at appropriate places inside the seat near the surface of the backrest. Therefore, all of these acupressure massagers are installed in a specific seat, are not portable, and cannot be used for home or office use.

In addition to the above-mentioned built-in type, various types of acupressure massagers that can be attached to and detached from a seat or a chair for an automobile have been developed, and these acupressure massagers have portability and, if necessary, can be used in automobiles. It can be installed in the seat. As this type, those described in, for example, Japanese Utility Model Laid-Open No. 56-63356, Japanese Utility Model Laid-Open No. 60-124929 and Japanese Patent Laid-Open No. 63-226356 are known. The shiatsu massager described in the first publication is designed to be freely attached to the seat of a vehicle or the back of various chairs as needed, and the shiatsu massage described in the second publication. The vessel is attached to the seat using a binding string. Further, the acupressure massager described in the third publication is such that a acupressure roller device is horizontally provided on a cloth belt and the acupressure roller device is moved up and down together with the conveyor belt.
