2. Description of the Related Art Various types of massage machines are conventionally known, and a typical example is a chair-type massage machine. This type of conventional massage machine is configured so that the massaging wheel can move up and down along both sides of the human spine, and can move the massaging wheels on the left and right around the spine in a certain range, respectively, in opposite directions. . However, since the massaging action of the massaging wheel in this type of massaging machine is limited to a limited position on both sides centering on the spine, for example, if the user wants to massage a little more toward the end of the shoulder, The fact is that he is moving his body sideways. However, Japanese Patent Application Laid-Open No. 60-1064 discloses a technique in which left and right massaging wheels can be moved in the same direction while maintaining the same pitch in order to massage the legs.
No. 54 proposes this.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The left and right massaging wheels disclosed in JP 06454 Gazette, for example, can be used for the massage of the upper body of the human body in addition to the legs, but to massage the end of the shoulder, leave the same pitch, left or Even if it is moved to the right, the massage wheel only moves sideways in a straight line, so the massage wheel located near the spine and the massage wheel located far from the spine,
The contact state of the kneading wheel with the back of the curved human body is different. In other words, the kneading wheel at a position far from the spine touches the user's back lightly, but the kneading wheel at a position near the spine touches strongly. Therefore, there is a problem that the massage by the left and right kneading wheels does not act evenly on the back. Therefore,
There is an inconvenience that the user himself has to move his body diagonally and adjust so that the left and right massaging wheels act evenly on the back.

The present invention has been made for the purpose of improving the above-mentioned problems in the conventional massage machine.
