Move up accordingly. On the other hand, the leading end of the pipe 42 is raised by the rod 46 and the guide member 38 so that the moving distance at which the leading end of the pipe 42 rises is greater than the moving distance at which the rear end of the pipe 42 moves upward. By setting the inclination angle α of the rod 46 to a predetermined angle, the tip of the pipe 42 is inclined so as to face upward.

That is, when the backrest 12 is tilted backward, the front end of the seat 11 is lifted upward, and the seat 11 is lifted.
Is tilted rearward so that the rear is lower than when the backrest 12 is raised, as shown in FIG. This seat 1
Due to the backward inclination of 1, the legs are lifted up and the body is slightly bent.

On the other hand, the rotation of the backrest frame 60 about the axis 66 causes the arm member 48 to move forward and the footrest frame 50 to rotate about the axis 55 in the direction of arrow Q2, as shown in FIG. The tip side of the footrest portion 13 is lifted up as shown in FIG.

Then, in the same manner as described above, the operation switch of the operation unit 16 is operated to set the massage mode in which massage is performed by the airbags 20 and 21, and the start switch is operated. Then, the control device 110 controls the pump 31 and the solenoid valves 102 and 103,
0,21 is expanded and contracted, and massage of the leg and buttocks is performed.

In this case, even if the backrest 12 is tilted down and the weight is hung rearward and the front side of the thigh is slightly lifted,
Since the seat portion 1 is inclined so that the rear portion becomes lower, the airbag 20 does not separate from the thigh, so that the airbags 20, 21 can sufficiently press the thighs and the buttocks as the seat portion. And a sufficient massage effect can be obtained.

If another mode is set by operating the operation switch of the operation unit 16, the airbags 22 to 29 are inflated and contracted, so that massage of the feet, waist, back, neck and the like can be performed.

In the above-described embodiment, the airbags 20, 21 are provided on the seat portion 11, but a vibrating treatment element or the like may be provided instead of the airbags 20, 21. in this case,
Since the treatment element presses the leg when the seat portion 11 is inclined rearward, the operation of the treatment element can sufficiently act on the leg.
