The durability of the bag 80 can be improved.

Each bag 40 to 46 as a treatment element is provided.
The air supply means 111
And the bellows-like bag 80 is smaller than the supply amount of air per unit time to each of the bags 40 to 46.
Since the amount of air supply per unit time to the unit is reduced, the speed at which the movable table 70 moves can be reduced, so that the movable table 70 can be moved slowly and the leg bag 46 can be moved.
Can be easily positioned so as to correspond to a desired treatment portion.

In the above-described embodiment, the treatment element is constituted by a bag which expands and contracts by supplying and exhausting air. It may be driven by driving means.

In the above embodiment, the fixing base is constituted by the fixing base 60 of the leg mounting base 50,
Although the movable table is configured by the movable table 70 that moves with respect to the fixed table 60, for example, the fixed table is configured by the frame member of the backrest 30, and the movable table is vertically moved by the frame member. It may be constituted by a base member provided with a neck bag as a treatment element.

Although the leg bag 46 is provided on both side walls of the mounting portion 71, it may be provided only on the bottom wall, or may be provided on both the side walls and the bottom wall. It is good also as a structure arrange | positioned at.

In the above-described embodiment, the driving bag is constituted by the bellows-shaped bag 80. However, as shown in FIG. 9, the driving bag is formed of a plurality of independent bags formed in a substantially flat shape. 180 are overlapped, and the bag bodies 180 at both ends in the axial direction are arranged so as to be in contact with the first contact plate 65 of the fixed base 60 and the second contact plate 72 of the movable base 70, respectively. Alternatively, a configuration may be adopted in which a branch hose 181a branched from the air hose 181 is connected to each of the bag bodies 180, and the air hose 181 is connected to the air supply means 111.

As described above, according to the first aspect of the present invention, a movable table provided with a treatment element is movably provided on a fixed table provided on a chair body having a seat and a backrest. Is moved by a bag that expands and contracts by the supply and exhaust of air from the air supply means and expands and contracts in the direction of movement of the movable table. And the like are less likely to occur, and the cost can be reduced.

According to a second aspect of the present invention, in addition to the effect of the first aspect, the driving bag in the first aspect of the present invention is constituted by a bellows-shaped bag. Since the length of expansion and contraction of the bag body can be increased, the moving distance, that is, the movable range can be increased.

According to a third aspect of the present invention, in the invention of the second aspect, the maximum moving length of the movable table relative to the fixed table is smaller than the length of the bellows-shaped bag in a free state. Therefore, in addition to the effect of the invention described in claim 2, even in a state where the movable table has moved the largest with respect to the fixed table, since the bellows-like bag does not extend beyond the length in the free state, This has the effect of increasing the durability of the driving bag without causing excessive stress to be applied to the driving bag during extension.

According to a fourth aspect of the present invention, there is provided the driving bag according to the first to third aspects, wherein the driving means comprises an air supply means and the treatment element is expanded and contracted by air supply and exhaust. Claims 1 to 3 in which the air supply amount per unit time to the driving bag is smaller than the air supply amount per unit time to the driving bag. In addition to the effects of the third aspect of the present invention, the movable table can be moved at a slow speed relative to the solid table, so that the treatment element can be easily made to correspond to a desired treatment portion. This has the effect.
