A massage machine includes a body supporting portion which supports a body of a person to be treated and a massage mechanism which moves inside the body supporting portion along a body height direction of the person to be treated. The body supporting portion is divided in the body height direction into a base portion and a movable portion. The body supporting portion extends and contracts when the movable portion moves relative to the base portion. The massage machine is capable of adapting to the body size of the person to be treated by changing the treatment range of the massage mechanism by extending or contracting the body supporting portion.本創作提供一種按摩機,根據被分割的身體支承部的伸縮而使按摩機構的施療範圍也相應地發生變化,從而能夠對應被施療者的體格進行優質按摩。前述按摩機包括:支承被施療者身體的身體支承部;沿被施療者的身高方向在身體支承部內移動的按摩機構。沿被施療者的身高方向分割身體支承部,且身體支承部至少包括基部和可動部,藉由使可動部相對於基部移動,使身體支承部進行伸縮。1‧‧‧按摩機2‧‧‧靠背部3‧‧‧座部4‧‧‧踏腳5‧‧‧按摩機構6‧‧‧套罩構件10‧‧‧基部11‧‧‧可動部12‧‧‧基部導軌14‧‧‧可動導軌
