When the airbag case 42 is in the forward projecting state, the engaging projecting piece 43 is fitted into the engaging fitting hole 44 so that the side stagnation part 40 is not easily collapsed. Therefore, when the side stagnation part 40 is used, the side stagnation part 40 does not fall down and become a bending posture.
Note that, for example, an adult can operate the side kneading portion 40 so as to fall inward in the width direction (inward in the left-right direction) with a certain amount of force, whereby the engagement protrusion piece 43 and the engagement fitting hole 44 are engaged. The combined state should be releasable. By doing so, for example, when moving the chair type massage machine 1 again, for example, when moving, the side rubbing portion 40 can be bent and the backrest portion 4 can be packed into a compact luggage. It becomes like this.

It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown not by the above description but by the claims,
It is intended that all modifications within the meaning and scope equivalent to the terms of the claims are included.
