Therefore, when the air bags 41 and 42 are inflated and contracted by air supply / exhaust, the treatment part 4a can massage the body part by applying a compression stimulus.

 When the first strobe 30 (see also FIG. 5) is operated from this state in the same manner as in FIG. 7, the treatment portion 4a moves up and down along the swing frame 11a of the swing base 10 together with the support portion 20. It becomes possible to slide. That is, the treatment part 4a shown in FIG. 8 (a) that can change the posture of the lower leg 100 of the user can slide up and down along the longitudinal direction of the lower leg 100. Then, as shown in FIG. 8 (b), when the treatment part 4a is positioned at the lowermost part, the treatment part 4a supports the lower part of the lower leg 100 (lower calf and ankle) from behind and inflates the air bags 41 and 42. This body part can be massaged. The vertical position of the treatment portion 4a can be adjusted to an arbitrary position depending on the formation position of the engagement hole 14 between the two positions shown in FIG.

 [0045] Fig. 9 is a side view for explaining the position adjustment along the front-rear direction of the foot of the user with respect to the treatment portion 4a in the deployed footrest 4, and (a) shows the treatment portion 4a most. V is shown in the state of being moved closer to the back (heel side), (b) being moved slightly forward from that state, and (c) being moved forward (toe side).

[0046] In the state shown in Fig. 9 (a), the footrest 4 is unfolded by the operation of the second stopper 50 (see Fig. 6), and the treatment portion 4a is placed on the floor with the support surface 40c facing upward. In addition, the support portion 20 is located at the uppermost portion along the swing frame 11a. At this time, the treatment part 4a is in the most rearward position, and supports the foot 101 of the user who is seated on the seat part 2 from the sole side. Therefore, by inflating and contracting the air bags 41, 42, it is possible to massage by applying a compression stimulus to the ankles and the insteps. In addition, when the treatment part 4a is arranged close to the seat part 2 in this way, it is preferable when a child, a small woman, or the like receives a foot massage. [0047] From this state, when the first strobe 30 is operated in the same manner as in FIG. 7 and the support portion 20 is slid downward along the swing frame 11a, the treatment portion 4a is shown in FIG. 9 (a). The position can be adjusted forward from the position. FIG. 9 (b) shows the position of the treatment part 4a when the support part 20 is positioned at the lowermost part of the swing frame 11a when the position is adjusted in this way.

 [0048] Further, when the air bag 35 disposed behind the support portion 20 is supplied and inflated, the swing frame 11a swings forward about the pivot (third axis) 13 forward. The treatment section 4a can further adjust the front position from the state shown in FIG. 9 (b). FIG. 9 (c) shows the position of the treatment portion 4a when the swing frame 1la is swung to the maximum angle when the position is adjusted in this way. Note that the position in the front-rear direction when the treatment part 4a is used for foot massage can be adjusted to any position between the three positions shown in FIG. As described above, the treatment unit 4a can be arbitrarily adjusted within a predetermined range from the position shown in FIG. 9 (a), so the treatment unit 4a is arranged to be suitable for each person having various physiques. It can be made. For example, in addition to the position suitable for children and small women as shown in FIG. 9 (a), the position of the treatment part 4a shown in FIG. The position of the treatment part 4a shown in c) may be suitable for a large tall man.

 [0049] In addition, the chair-type massage machine according to the present embodiment expands the footrest 4 for massaging the foot of a large user as shown in FIG. While not in use, the footrest 4 can be folded to place the treatment portion 4a close to the seat portion 2 as shown in FIG. 7 (a). Therefore, the installation space when not in use can be reduced.

 [0050] [Functional block of chair type massage machine]

FIG. 10 is a functional block diagram showing the configuration of the chair type massage machine 1 as described above. As shown in FIG. 10, the chair type massage machine 1 includes a control unit 80, and the control unit 80 is stored below the seat 2. The control unit 80 is connected to an operation unit 81 such as a remote controller operated by the user and drive units 82 and 83. An air supply / exhaust device 84 having a pump and a solenoid valve (not shown) is connected to one drive unit 82, and the air supply / exhaust device 84 is used for massage for applying a compression stimulus to the body part of the user. The air bags 2b, 3a, 41, 42 are connected to the air bags via air hoses. The other drive unit 83 has the above-mentioned supply. An air supply / exhaust device 85 having a larger capacity than that of the exhaust device 84 (high air supply capacity V) is connected to the air bag 35 and the air hoist for swinging the footrest 4 back and forth. Connected through the network.

 [0051] In such a chair type massage machine 1, a control signal is sent from the control unit 80 to the drive units 82 and 83 in accordance with the operation of the operation unit 81 by the user. The drive unit 82 that has received this control signal drives the air supply / exhaust devices 84 and 85 according to the contents thereof, and selectively supplies and exhausts air to / from one or more of the air bags 2b, 3a, 41 and 42 and the air bag 35 This is expanded or contracted. As a result, as already explained, when the air bag 2b is inflated and inflated, massage is applied to the thigh and buttocks of the user, and when the air bag 3a is inflated and inflated, massage is performed on the upper back of the user.
