BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for moving acupressure balls, which are arranged at least in pairs on the left and right, back and forth to perform acupressure operation by the acupressure balls. It is constructed so that the forward / reverse rotation of the drive shaft of the acupressure drive motor can be directly transmitted to the supporting screw rod, and a pair of acupressure balls are moved forward and backward or approach / separate, so that the user can use acupressure massage or kneading acupressure massage. The present invention relates to an acupressure device for performing the following.

[0002]

2. Description of the Related Art Conventionally, various types of massage machines have been developed as massagers for massaging human body parts. For example, a forward / backward rotatable screw shaft is provided in a backrest portion of a chair or the like or in a bed. Then, by screwing a massaging body, which performs repetitive horizontal rocking and repetitive vertical rocking on a pair of massaging balls, to the screw shaft, other than a massaging massage or a tapping massage, a sliding massage, etc. The massage machine that is performed is very useful to general consumers because the effect of using the massage machine can be obtained well. Also, in recent years, there is a strong demand for a shiatsu massage device which has a different operation from the above-mentioned massage machine, and which is capable of moving a shiatsu ball in and out so as to be able to press and massage a pot of a human body part. However, most of the currently-developed acupressure massage devices have a structure in which a cam body is activated by a motor, and a rotation of the cam body causes an acupressure ball disposed and engaged with the cam body to protrude and retract. Because the holding structure for the cam and the acupressure ball is not formed, depending on the angle of use, the acupressure ball and the cam are not in contact with each other, and only the cam is idle and the acupressure ball cannot be repeatedly moved in and out. There was a problem. In order to solve the above-mentioned problems, the inventor of the present application attaches a driving motor for acupressure to a lower portion of a mechanism frame forming an outer frame, and controls the driving rotation of the motor by a driven shaft and a main driving shaft in the frame. The guide shafts are provided opposite to both ends of the main drive shaft outside the mechanism frame, and the sliding plates provided on both sides of the mechanism frame are provided in the elliptical grooves formed in the guide plate. A floating pin is loosely fitted, and a supporting plate provided with a shiatsu ball is provided between the front ends of the pair of sliding plates so that the shiatsu ball can smoothly appear and disappear at any use angle. The acupressure device for massage (Japanese Patent Application No. 1-14050) has already been invented and commercialized.

[0003]

However, in the above-mentioned massage acupressure device, a motor for driving acupressure is attached to a lower portion of a mechanism frame, and the rotation of the motor for acupressure is controlled by a driven shaft or a driving motor. Since this is a transmission mechanism that transmits to the slide guide plate via the shaft, and further transmits this to the sliding plate via the floating pin to cause the acupressure ball to move forward and backward, many parts are required. There is a problem that the engagement structure of the
Due to such a problem, a problem such as a noise problem in the transmission unit or a failure of the transmission component is caused. Further, the above-mentioned conventional apparatus has a disadvantage that the size of the apparatus is very large due to the connection parts, and it is almost impossible to reduce the size. Therefore, recently, there has been a strong demand for the development of a compact and lightweight acupressure device that can be manufactured at a low cost by simplifying the transmission mechanism as much as possible. It is not at present.

[0004]
