Specifically, the urging member 14 is constituted by a coil spring, and one end of the coil spring is attached to the leg frame 5 side (fixed side), and the other end is attached to the swing arm 17. The oscillating arm 17 is urged outward in the width direction around the pivot 18 of the pivot base 13 by the twisting force of the coil spring.

The airbag 15 is provided between the back surface (the outer surface in the width direction) of the mounting body 16 of the support member 12 and the side wall member 19 that constitutes the armrest portion 6.
The airbag 15 of the present embodiment has a structure in which a first airbag 20 connected to the back surface of the attachment body 16 and a second airbag 21 (backup bag) provided on the armrest side are overlapped and connected. Yes.

  Each of the first airbag 20 and the second airbag 21 is formed by overlapping two circular cloth bodies having no air permeability. The peripheral portions of the two cloth bodies are joined together by sewing or adhesion. The first airbag 20 and the second airbag 21 are stacked, and a circular central portion is configured to communicate with each other, and the interiors of both airbags 15 communicate with each other so that air can pass therethrough. .

  The airbag 15 having such a structure has a thin and flat outer shape when air is not supplied from an air supply means (not shown) provided in the chair type massage machine 1, but when air is supplied, Both the first airbag 20 and the second airbag 21 bulge out from the armrest portion 6 and cause the side pressing portion 11 to protrude from the armrest portion 6 while resisting the pulling force of the urging member 14. Thereby, the airbag 15 presses the side part pressing part 11 to massage the side part of the user's buttocks and thighs seated on the seat part 2.

  In the case of this embodiment, the air supply means described above is built in the chair type massage machine 1 and can supply air to the left and right airbags 15. The air supply means temporarily stops the supply of air when the inside of the airbag 15 reaches a predetermined pressure, and can be held in that state. Moreover, the air in the airbag 15 can be vented by opening the release valve provided in the air supply means.

By repeating such air supply, stop, and discharge, the air supply means inflates or contracts the airbag 15.
The movement of the side massage mechanism 10 of the chair type massage machine 1 having the structure as described above, in particular, the movement of the drive unit 22 will be described below.
In addition, although the side part massage mechanism 10 exists in a pair of right and left, since the movement is substantially the same, the side massage mechanism 10 on the right side will be described below.

  As shown in FIGS. 4 and 5A, in the chair-type massage machine 1 according to the present embodiment, the air supply means is not operating and air is supplied to the airbag 15 before the operation is started. Absent. Therefore, the airbag 15 is in a contracted state, and the support member 12 is attracted to the armrest portion 6 side by the urging member 14 and stands. At this time, the side pressing portion 11 attached to the upper end side of the support member 12 is held in an embedded state in a state of protruding several cm from the inner side surface of the armrest portion 6.

When the user sits on the seat portion 2 of the chair type massage machine 1 in which the side pressing portion 11 is stored and operates the chair type massage machine 1, the air supply means starts to supply air to the airbag 15. .
Then, as shown in FIGS. 3 and 5B, the right airbag 15 starts to inflate with the supply of air from the air supply means. When the air pressure in the airbag 15 exceeds the pull back force of the urging member 14, the support member 12 starts to swing in a direction (inward in the width direction) close to the seat 2 with the pivot base 13 as a fulcrum. The side pressing part 11 attached to the upper end side of the support member 12 is placed on the user's treatment part (the right side of the thigh to the right side of the heel) in accordance with the falling and swinging movement. It comes into contact and presses.

Even after the side pressing portion 11 comes into contact with the treatment portion, the treatment portion can maintain the pressure massage state by supplying air until the air supply means reaches a predetermined pressure.
Thereafter, if the air supply means is operated to remove air from the airbag 15, the support member 12 is pulled back to the armrest 6 side (width direction outer side) by the pulling force of the urging member 14. At this time, the airbag 15 is pushed by the pulling force of the urging member 14 so as to be in a flat state. As a result, the air inside is released and the side pressing portion 11 returns to the stored state.

By repeating the supply, stop, and exhaust of air as described above, in the user's treatment unit, pressing and releasing by the side pressing unit 11 are repeated, and pressing massage is performed.
When the chair type massage machine 1 is stopped after the press massage is finished, the operation of the air supply means is also stopped. At that time, the support member 12 is immediately pulled back in the direction of separation by the urging member 14, so that the air of the airbag 15 can be quickly extracted by the pulling force. As a result, the side pressing portion 11 quickly moves away from the user's treatment portion and is placed in the armrest portion 6. Therefore, the side pressing portion 11 does not interfere with the user's standing / sitting operation.

The operation mode of the right side massage mechanism 10 has been described above, but the operation mode of the left side massage mechanism 10 is also substantially the same as that on the right side.
Therefore, the left and right pair of side massage mechanisms 10 are driven in synchronism with each other, and the side pressing portion 11 is moved closer to or away from the seat portion 2 side, so that the left and right treatment portions of the user can be operated. You will be able to press massage. Note that the pressing timing by the side pressing portion 11 may be the left and right at the same time, or by moving the other side pressing portion 11 away from each other when the one side pressing portion 11 is operated in proximity. You may press a user's right and left treatment part by turns. As described above, various pressing massage menus can be realized by changing the timing of the approaching operation and the separating operation of the side pressing unit 11 by the left and right side massaging mechanisms 10 (particularly, the drive unit 22).

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
The airbag 15 has a structure in which two circular cloth bodies having no air permeability are stacked, the structure in which the first airbag 20 and the second airbag 21 are laminated, and the like. It is not limited. For example, the airbag 15 may have a bellows structure or a single bag structure in a direction in which expansion and contraction are performed.
