The rear legs 7, the front legs 8 vertically extending downward from the front end of each main body 6, the upper horizontal part 9 connecting the upper ends of the front legs 8, and the lower ends of the front legs 8 It is a rigid body composed of a connected lower horizontal part 10 and a reinforcing part 11 which connects the lower end of each front leg 8 and the lower end of each rear leg 7. Specifically, the seat mounting portion is a portion surrounded by a pair of main portions 6 and an upper horizontal portion 9, and a planar spring 12 is disposed between the pair of main portions 6. It is configured. That is, the seat 1 is placed on the sheet spring 12 so that the user can comfortably sit on the seat 1 by the cushioning property of the sheet spring 12. An armrest 13 is provided on each side edge of the seat 1 in the width direction (FIG. 4). The armrest 13 is fixed to the framework 5 so that the framework 5 is embedded therein.
[0013]
The backrest 3 has the treatment mechanism 2 built therein as described above. The treatment mechanism 2 includes a treatment mechanism main body 2a that can move up and down in the backrest portion 3, and a treatment element 2b that projects forward from the treatment mechanism main body 2a and presses against the body of the user to perform treatment. The treatment mechanism main body 2a is movable up and down of the backrest portion 3, and the treatment element 2b is movable in the left-right direction with respect to the treatment mechanism main body 2a. Specifically, the structure of the backrest portion 3 incorporating the treatment mechanism 2 is such that a groove-shaped treatment mechanism slide portion 14 extending vertically is formed inside the backrest portion 3, and the treatment mechanism slide portion 14 is provided on the treatment mechanism slide portion 14. 2 is accommodated so that the treatment mechanism 2 can be moved up and down. The surface of the treatment mechanism slide portion 14 is covered with a cover material such as leather or cloth, like the rest of the backrest portion 3. The treatment mechanism slide portion 14, which is the moving range of the treatment mechanism 2, constitutes the treatment range. However, the massage chair is originally required to have a large treatment range. Even in the massage chair of this example, the peripheral portion of the backrest 3 is used. The treatment mechanism slide portion 14 is formed in a wide area with the remaining. In order to allow the treatment mechanism 2 having a wide treatment range to effectively act on the user, the backrest portion 3 is disposed adjacent to the rear portion of the seat portion 1 so as to be reclined via the above-described drive mechanism 4. ing.
