Effects such as loosening can be obtained. That is, this chair type massage machine can perform a soft treatment method performed manually. In addition, the soft treatment method performed manually is as follows: (1) Grasp the patient's ankle placed on the treatment table (2) Pull the leg (increase the vertebra interval) (3) Shake the leg (intervertebral disc, The position of the pelvis is corrected), and the pelvis and the like are swung by swinging left and right while pulling the leg. On the other hand, the treatment method performed by this chair type massage machine moves the seat body 5 with the lumbar part on the left and right, so the operation is relatively similar to the operation of shaking the leg performed manually, but the pelvis etc. This is effective for the correction.

  As another means for extending the user's lower body, the leg rest 3 is configured to be driven in a direction toward or away from the seat 1 along the length of the leg. While the user's leg is held, the control means moves the leg rest part 3 in a direction away from the seat part 1. Accordingly, the lower body of the user whose legs are held by the air cell 19 can be extended. Even in this case, effective left and right movements are performed on the user's lower back, so that effective softening treatment can be performed.

  As yet another means for extending the user's lower body, an air cell 19 as a holding means provided on the leg rest 3 presses the user's leg in two directions and pushes the leg in the direction of the leg. It can comprise so that the operation | movement to press may be carried out. In this case, the air cell 19 can push the user's leg toward the tip of the leg, and the user's lower body can be extended through the leg. And in this state, the right-and-left direction exercise | movement is performed with respect to a user's waist | hip | lumbar part, and an effective softening treatment becomes possible.

As yet another means for extending the user's body (lower body), the user's legs are held by the holding means 19 in the raised or lowered state or the leg rest portion 3 in the intermediate position, that is, The backrest part 2 can be configured to be tilted backward in a state where the left and right legs of the user are sandwiched and held from the left and right directions by the leg resting part massage tool 19. In this case, since the position of the user's body (buttock) is shifted backward by tilting the backrest part 2 backward, a traction force acts on the user's body.
Or it can be set as the structure which lowers the said leg mounting part 3 from the state by which the user's leg was hold | maintained by the said holding means 19 in the leg mounting part 3 in the raising state. In this case, since the leg is pulled toward the leg tip side, a traction force acts on the user's body. Further, the leg rest part 3 may be lowered and the backrest part 2 may be tilted backward.
In each of these states, the seat body 5 is moved left and right to perform a lateral movement with respect to the user's waist, thereby enabling more effective softening treatment.

  Further, as a means for moving the seat body 5 on which the user is seated by moving left and right, as shown in FIG. 18 can be used. That is, by alternately expanding and contracting the left and right air cells as the tilt driving means 18, it is possible to repeatedly perform a posture in which the seat surface 5a of the seat body 5 is tilted downward to the right and tilted to the left. . According to this, the waist can be swung three-dimensionally. Alternatively, the seat body 5 may be moved left and right by the left and right drive means 8a and 8b, and the seat body 5 may be swung in the height direction by the tilt drive means 18.

In each of the above embodiments, when the seat body 5 is moved left and right to cause the user to exercise, it is preferable that the backrest portion 2 is tilted backward. Thereby, since the load on the user's spine caused by the weight of the upper body of the user is reduced, the operation of shaking the body left and right is facilitated, and the treatment effect can be further exhibited.
Further, in each embodiment, when the seat body 5 is moved left and right, not only can the leg rest portion 3 be in the most raised position or the most lowered position, but can also be in the intermediate position state. .

Furthermore, in each of the embodiments described above, when the seat body 5 is moved left and right to cause the user to exercise, the leg tip side portion 33c of the leg rest portion 3 is placed on the seat body 5 as shown in FIG. It can carry out as a position higher than the seating surface 5a. The leg tip side portion 33c includes a foot back surface 33a that opposes the user's sole in the foot insertion recess of the leg rest portion 3, and a leg back surface 33b that opposes the back of the ankle from the back of the user's calf. This is the part where and intersect.
That is, as the structure which makes the leg mounting part 3 the rising state which becomes an angle of 90 degrees or more with respect to a horizontal surface, makes a user's leg tip (foot sole) higher than the seat surface 5a, and moves the seat main body 5 right and left. Yes.
Further, in FIG. 9, when the leg rest portion 3 is lifted over 90 °, the seat portion 1 is inclined so that the horizontal seating surface 5 a tilts backward. And the leg back surface 33b and the seating surface 5a of the leg mounting part 3 will be in the state inclined downward. In this state, the user holding the leg on the leg rest portion 3 is subjected to a backward force depending on his / her body weight, so that the effect of stretching the body (lower body) is automatically generated, and the body is shaken left and right. The treatment effect which arises by operation | movement can be exhibited more.

  Further, in FIG. 9, the seat portion 1 is configured to be interlocked when the leg rest portion 3 is lifted beyond 90 °. However, even when the seat portion 1 is not interlocked, FIG. Can be configured. The seat portion 1 in FIG. 17 includes a front air cell 18a provided at the front portion of the seat portion 1 and a rear air cell 18b provided at the rear portion of the seat portion 1 as the tilt driving means 18 (see FIG. 1). ing. Then, when the front air cell 18a expands (and the rear air cell 18b contracts together with this), the seat surface 5a of the seat body 5 is inclined downward (the seat surface 5a is in a front-up state). By this operation, as in the case of FIG. 9, the leg back surface 33b and the seating surface 5a of the leg rest part 3 are inclined downward.
