The through hole 87 of the second swing shaft 86 is provided below the front surface of the second treatment element support 83, and the second attachment portion 88 is provided on the front surface of the second treatment element support 83. It is provided above.
The surface that receives the driving force from the strength adjustment mechanism 90 is located on the rear surface of the second mounting portion 88 so that the driving force can be easily transmitted to the second treatment element 81b.
Further, the second swing shaft 86 is provided with an urging means (not shown) for returning the second treatment element support 83 from the swinging state by the strength adjusting mechanism 90. When the adjustment mechanism 90 does not operate, the adjustment mechanism 90 is held along the first treatment element support 82.

The second treatment element support 83 has a drive receiving surface 92 so as to receive the driving force from the strength adjustment mechanism 90 and is wide in the left-right width direction of the backrest portion 2. Thereby, the surface on the second mounting portion 88 side is also widened in the left-right width direction.
The second treatment element support 83 has a cover part 89, and the cover part 89 is provided on the second treatment element support 83 so as to cover the second treatment element support 83. It is a size.
The cover portion 89 is provided to prevent interference between the second arm 80 and other members such as the backrest portion 2. Since the second arm is provided with the strength adjustment mechanism 90, the width in the left-right direction is increased, and the second arm interferes with the opening 21 of the backrest portion 2, and the strength adjustment mechanism 90 may be rubbed and damaged. By providing the cover portion 89, the strength adjustment mechanism 90 is prevented from being damaged.

Further, the surface on the second attachment portion 88 side has a treatment element 81 that supports the back back air cell L302a and the back back air cell R302b. Since the back back air cell L302a and the back back air cell R302b project into the opening 21, a part of the air cells in the opening 21 falls. The treatment element 81 is provided on the back side of the back back air cell L302a and the back back air cell R302b to prevent the back back air cell L302a and the back back air cell R302b from falling, and the back back air cell L302a and the back back air cell R302b are used for the user. Massage or stretching can be performed.
The treatment element 81 can support the back and back air cells L302a and R302b, and can push the back and back air cells L302a and R302b toward the user by the strength adjustment mechanism 90. Thus, a stretching operation that opens the chest to the user can be performed.
The treatment element 81 is at least partially overlapped with the back and back air cells L302a and R302b in the front-rear direction, and the massage unit 6 includes the treatment element 81, the back and back air cells L302a and R302b. The strength adjustment mechanism 90 is driven at the overlapping position. By comprising in this way, the treatment element 81 can extrude the back back air cell L302a and the back back air cell R302b to the user side.

Even when the strength adjustment mechanism 90 is operated, the relative distance between the first treatment element 81a and the second treatment element 81b is maintained. This is because the lower part of the second treatment element support 83 is provided on the second swing shaft 86 together with the first treatment element 81a, and the second treatment element 81b is provided on the upper part of the second treatment element support 83. In this state, the strength adjustment mechanism 90 swings around the second swing shaft 86 of the second treatment element support 83 as a fulcrum, so that the distance between the first treatment element 81a and the second treatment element 81b is maintained. Is done.
For example, if the distance between the first treatment element 81a and the second treatment element 81b is changed, the first treatment element 81a and the second treatment element 81b are brought into a close state, and a gripping operation is performed. As a result, the intensity of the massage operation during treatment cannot be adjusted.
By maintaining the distance between the first treatment element 81a and the second treatment element 81b in this way, the same type of massage operation can be adjusted in strength.

The strength adjustment mechanism 90 includes a bellows-like air cell 301a (301b), and is provided on the first attachment portion 85 of the first treatment element support 82.
Further, the first attachment portion 85 has a hole through which a pipe passes, and an air supply / exhaust port of the bellows-like air cell 301a (301b) is extended from there.
The strength adjusting mechanism 90 has a swing fulcrum on the first treatment element 81a side, and swings toward the user side by supplying air.
The bellows-like air cell 301a (301b) is preferably smaller than the treatment air cell (302a, etc.). By making the air cell small, it can be in an expanded state with a small amount of air, and strength adjustment with a fast response speed is possible.

An air pipe (not shown) connected to the air supply / exhaust port of the bellows-shaped air cell 301 a (301 b) is connected to the air supply / exhaust device 32 below the seat portion 3.
A throttle 37a is disposed in the middle of the air pipe, and the amount of air flowing into and out of the bellows-shaped air cell 301a (301b) of the strength adjusting mechanism 90 is suppressed.
Since the bellows-like air cell 301a (301b) of the strength adjustment mechanism 90 is smaller in size than other air cells, the reaction speed becomes too fast if air is introduced in the same manner as a normal air cell. 37a is provided to suppress the inflow and outflow of air.

The throttle 37a (37b, 37c) is formed of a tubular member that connects the pipes to each other so that they can be arranged in the middle of the air pipes.
Further, the restriction 37a (37b, 37c) may have a shape in which the inner diameter is simply reduced in the middle of the flow path, or may have a shape in which the inner diameter is gradually reduced.
For example, the inner diameter of the throttle 37a (37b, 37c) viewed from the strength adjustment mechanism 90 side (air outflow side) is simply a reduced inner diameter, and the throttle viewed from the air supply / exhaust device 32 side (air inflow side). When the inner diameter of 37a (37b, 37c) is gradually reduced toward the strength adjustment mechanism 90, the inflow of air is faster than the outflow of air. It is possible to add a change that is slower than the inflow of.
