It relieves fatigue and performs functions such as muscle relaxation, spinal correction, and massage.

The massage ball of this elevating type massage unit is configured such that a roller-type massage ball is rotatable on a horizontal axis having an axial direction in the left and right directions. Therefore, the rotational motion is smooth in the elevating direction around the axis, but in the other directions except the elevating direction, a sliding motion is formed, not a rolling motion, so that friction is generated between the backrest cover and the roller sampler. In particular, there is a problem in that the lifespan of the backrest cover is shortened due to left-right wear during the 'rubbing' massage operation.

In order to solve this problem, in Korean Patent Registration No. 10-1675454, a part of the spherical surface of the massage sphere in the form of a sphere, coupled to the end of the massage arm, protrudes toward the back of the subject and rotates in all directions. Thus, there is disclosed a patient unit including an axisless sampler capable of performing a rolling motion.
