[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for performing two different operations of acupressure massage and kneading massage by a single driving force, and more particularly, to forward / reverse rotation of a main driving shaft of a starting motor. The two different gears rotate independently of each other, and the kneading ball and the acupressure ball connected to each gear are operated independently in an independent state, and the two types of operations different from the kneading operation and the acupressure operation are appropriately performed. The present invention relates to an automatic massage mechanism that allows the user to perform massage.

In general, the back of the person is massaged and a tapping massage is performed.

A conventional massage machine of this type, for example, a chair-type massage machine, is also equipped with a lifting mechanism in which a motor for rotating the vertical screw shaft forward and reverse to move the massage mechanism up and down is arranged on the back of the chair. The massage mechanism and the elevating mechanism carry out massaging massage and tapping massage over the entire back of the user.

[0004] In recent years, there has been a demand for a massage machine capable of performing a rolling operation or acupressure operation of other functions instead of the above-described kneading operation or tapping operation. Therefore,
