It will be separated from the lower rubbing surface 541a and only the rotating wheel 743a will be in contact with the rubbing surface 541a.

  The above-described sliding body 7a rotates the rotating wheel 743a in contact with the lower rubbing surface 541a in the guide rail 54a, and only on the rubbing surface 541a on the upper side in the guide rail 54a. However, the configuration shown in FIGS. 33 and 34 is obtained by reversing the position configuration of the rotating wheel 743a and the rubbing member 72a upside down.

  That is, the base end portion of the frame 71a is pivotally connected to the lower end of the hanging frame 53a via the pivoting portion 73a as described above, and the slide on the upper side in the guide rail 54a is located on the upper end of the frame 71a. The rubbing member 72a is provided so as to be rubbed on the rubbing surface 541a, and is rotated in contact with the rubbing surface 541a on the lower side in the guide rail 54a at an intermediate position between the rotating portion 73a and the rubbing member 72a. The rotating wheel 743a is provided for this purpose.

  Also by configuring the sliding body 7a in this way, the rotational movement in which the sliding with the frictional resistance by the sliding member 72a is temporarily released and the frictional resistance by only the rotating wheel 743a is reduced as much as possible. Thus, the smooth movement of the movable armrest 502a can be realized. That is, when the user lifts the front side of the movable armrest 502a upward, the drooping frame 53a is lifted upward as shown in FIG. 36. Accordingly, the rubbing member 72a slides on the upper side in the guide rail 54a. The surface is separated from the surface 541a and only the rotating wheel 743a is in contact with the rubbing surface 541a. In this state, the sliding body 7a can smoothly slide in the guide rail 54a. Next, when the upward lifting of the movable armrest 502a is stopped, the drooping frame 53a is pushed downward by its own weight, and the rubbing member 72a is again pressed against the rubbing surface 541a on the upper side in the guide rail 54a.

  Further, when the user deliberately pushes down the movable armrest portion 502a or places a hand portion or an arm portion on the movable armrest portion 502a to apply a natural load, the friction member is strongly increased accordingly. 72a is pressed against the rubbing surface 541a. Therefore, sliding of the sliding body 7a on the guide rail 54a can be suppressed, and the movable armrest 502a is prevented from moving unexpectedly. In particular, when a hand or arm is placed on the movable armrest 502a and the treatment is performed by the arm kneading mechanism 51a, the user can devote himself to the treatment with peace of mind because the movable armrest 502a is stably stationary. In addition, when a large load is applied to the movable armrest portion 502a, the rubbing member 72a is more strongly pressed against the rubbing surface 541a and the movable armrest portion 502a is fixed and stationary, so that the user can move with peace of mind. It is possible to stand up or sit down while putting weight on the armrest 502a.
