The position exceeding the left and right leg length determination values may be detected by the above-mentioned leg mounting position detecting unit 22. Then, the position exceeding the leg length determination value of the left leg detected as described above may be compared with the position exceeding the leg length determination value of the right leg, and the left and right leg length difference information may be acquired. That is, in this case, the leg mounting position detection unit 22 also functions as the left leg detection unit 27A and the right leg detection unit 27B. For example, the position where the right leg detection unit 27B detects the contact of the right foot sole (the leg length determination value) is higher than the position where the left leg detection unit 27A detects the contact of the left foot sole (the position exceeding the leg length determination value). If the position (above) is on the lower side, it may be estimated that the length of the right leg is larger than that of the left leg. The left and right leg length difference information may include the magnitude information of the left and right leg length difference as described above. The mode for acquiring the left and right leg length difference information is not limited to the above-mentioned mode, and various other modes can be adopted.

As shown in FIG. 3, the control unit 19 executes a tilt detection mode for estimating the vertical tilt of the left and right pelvis of the treated person based on the above-mentioned leg length difference information (step S103). With such a configuration, it is possible to detect the vertical tilt of the left and right pelvis of the treated person based on the leg length difference information, and it is also possible to perform effective treatment according to the tilt of the pelvis. Become.
In other words, if there is a difference in the length of the left and right legs, it is estimated that the pelvis is distorted (tilted). As shown in FIG. 4A, if the length of the right leg is larger than that of the left leg, it may be estimated that the right pelvis is lower than the left pelvis. The inclination of the pelvis may include information on the magnitude of the inclination.

With such a configuration, the tilting mechanism 5 is operated in a direction to alleviate or eliminate the vertical tilting of the pelvis, and the posture can be corrected. In addition, it is possible to perform treatment with the posture corrected in this way.
When the right pelvis is lower than the left pelvis as described above, as shown in FIG. 4 (c), the right air cell 6B is inflated more than the left air cell 6A to lift the right pelvis (right buttock). You may try to correct it. That is, the tilting mechanism 5 may be controlled so that the pelvis of the treated person is tilted to the side where the tilt detected as described above is relaxed or eliminated. In this correction mode, the lifting amount of the left and right pelvis (buttocks) may be changed according to the magnitude of the vertical inclination of the left and right pelvis. In this correction mode, the appropriate treatment mode may be executed by various treatment mechanisms such as the treatment unit 10 and the air cell described above in the corrected state as described above, or the appropriate treatment mode may be executed. The correction mode may be executed during. At this time, depending on the detected inclination, the strength, the number of times, the order, etc. may be different between the right side and the left side for treatment. As a treatment mode, for example, based on the above-mentioned difference in leg length and inclination of the pelvis, the pelvis of the treated person is tilted so that the acupuncture points (pots) around the muscles and the surroundings, which are considered to be the cause, are effectively treated. The treatment may be performed in the same state, and various treatment modes can be executed.

As an embodiment in which the other of the left air cell 6A and the right air cell 6B is inflated to lift one of the left buttocks and the right buttocks, for example, one is contracted by exhaust gas and the other is expanded by air supply. It may be a mode in which the left and right sides are expanded by air supply and one of them is contracted by exhaust gas, and various other modes can be adopted. Here, the contraction of one is not limited to the state of being completely contracted and may be a state of being contracted more than the other, and the expansion of the other is not limited to the state of being completely expanded and is expanded more than the other. It suffices if it is in the same state.
As a mode for changing the lift amount of the left buttocks and the right buttock, a mode of changing the air supply / discharge amount (supply / discharge time) to the left air cell 6A and the right air cell 6B may be used, and the left and right lift amounts are detected. The mode may be changed by controlling the air supply / exhaust unit based on the detection of an appropriate detection unit, and various other modes can be adopted. The tilting mechanism 5 is not limited to the mechanism tilted by the air cell as described above, and an appropriate advancing / retreating mechanism may be provided on each of the left and right sides to tilt the mechanism 5.
