[1st massage operation]
The first massaging operation is a massaging operation that provides finger pressure on the back of the buttocks or thighs. First, the control unit 13 drives the lifting motor M1 to move the massage unit 9 to the seat 3. Subsequently, as shown in FIG. 21A, the left and right air cells 11L and 11R are inflated to hold the user's waist from both sides (first operation state 1). Subsequently, as shown in FIG. 21B, the air cell 63 for advancing and retracting is expanded in a state in which the expansion of the air cells 11L and 11R is maintained, and the massaging unit 9 is set to the projecting position (first operation state 2). Then, with the expansion of the air cells 11L and 11R maintained, the expansion and contraction of the forward and backward air cells 63 are repeated for a predetermined time.

  As described above, the massage unit 9 is advanced and retracted while the waist is held by the air cells 11L and 11R on the left and right sides, so the body does not lift up from the seat, and finger pressure action is effected by the treatment element 62b on the buttock or thigh Can be given. Also, in the first massaging operation, instead of or in addition to the expansion and contraction of the air cell 63 for advancing and retracting, the massage motor M2 is driven to massage and / or beat the buttocks or thighs to the massage unit 9 It is also possible to In this case, the body does not shake in the left and right direction, and the massaging element 62b can provide a good itching and tapping action to the buttocks or thighs. Furthermore, the vibration due to the tapping is transmitted to the air cells 11L and 11R that press the waist, and it is possible to give the waist a feeling that it is striking.

[2nd massage operation]
The second massaging operation is a massaging operation that gives the back of the buttocks or thighs a finger-pressing action, itching action, or a tapping action while the body is twisted left or right or moved left or right. It is. First, the control unit 13 drives the lifting motor M1 to move the massage unit 9 to the seat 3. Subsequently, as shown in FIG. 22 (a), while the air cell 11L on the left side is inflated to twist or move the body to the right, the massage unit 9 is massaged and / or struck with the protruding position (second operation state 1 ). Subsequently, as shown in FIG. 22 (b), while contracting the left air cell 11L and expanding the right air cell 11R to twist or move the body to the left, it massages and / or strikes with the massage unit 9 at the protruding position. Continuously (second operating state 2). Then, after repeating the second operation state 1 and the second operation state 2 alternately a predetermined number of times, the air cells 11L and 11R and the air cell 63 for advancing and retracting on both left and right sides are contracted and stagnation and tapping are stopped. It will be in the state shown in).

  Thus, while the body is twisted left or right or left or right by the left and right air cells 11L, 11R, finger pressure, itching, or tapping is performed on the back of the buttocks or thighs. Therefore, the sense of massage by the massage unit 9 and the massage part can be changed. Specifically, in a state in which the air cell 11L on the left side is inflated and the body is twisted to the right or moved to the right (second operation state 1), the treatment element 62b of the massage unit 9 is the hip or thigh It strongly abuts on the right side of the part and massages the position on the left side. On the other hand, when the air cell 11R on the right side is inflated and the body is twisted leftward or moved leftward (second operation state 2), the treatment element 62b of the massage unit 9 is on the left side of the buttock or thigh Strongly in contact with and massage the more right position. In the second massaging operation, it is also possible to drive only one of the massaging motor M2 and the advancing and retracting air cell 63.

[Third massage action]
The third massaging operation is a massaging operation in which the buttocks are moved in the left-right direction and the up-down direction to give a stretching action to turn the pelvis. First, the control unit 13 controls the lift motor M1 to move the massage unit 9 to the seat 3. Subsequently, as shown in FIG. 23 (a), while expanding the left air cell 11L and twisting or moving the body to the right, the air cell 63 for advancing and retracting is expanded and the body is lifted by the massage unit 9 (third operation State 1). Subsequently, as shown in FIG. 23B, the air cell 11L on the left side is contracted to straighten the posture or return the body to the center position in the left-right direction (third operation state 2). Subsequently, as shown in FIG. 23C, the air cell 11R on the right side is expanded to twist or move the body to the left side (third operation state 3). Subsequently, as shown in FIG. 24 (d), the right air cell 11R and the forward / backward air cell 63 are contracted to straighten the posture or return the body to the center position in the left-right direction and lower the body (third operation state 4). The cycle of moving from the third operation state 1 to the third operation state 4 is repeated a predetermined number of times.

  As described above, by combining the left and right movement of the body by the left and right air cells 11L and 11R and the up and down movement of the body by the massage unit 9, it is possible to perform a stretch that turns the pelvis. In the third massage operation, it is also possible to drive the massage motor M2 to cause the massage unit 9 to massage and / or strike the buttocks or thighs. Further, the transition from the third operation state 1 to the third operation state 3 may be made directly, omitting the transition to the third operation state 2. In addition, during the execution of the third massage operation, the transition order from the third operation state 1 to the third operation state 4 may be reversed.

[The 4th massage operation]
The fourth massaging operation is a massaging operation giving a sense of stretching that stretches the muscles of the buttocks or thighs in the direction of height. First, as shown in FIG. 24A, the control unit 13 expands the air cell 12 to hold the legs of the user from both sides (fourth operation state 1). Subsequently, as shown in FIG. 24 (b), while maintaining the expansion of the air cell 12, while gradually expanding the forward and backward air cell 63, the massage unit 9 is forward in the seat portion 3 (height direction toe side ) (4th operation state 2). Subsequently, while gradually contracting the air cell 63 for advancing and retracting, the massage unit 9 is moved backward (head side in the height direction) at the seat portion 3 to return to the fourth operation state 1 shown in FIG. . The fourth operation state 1 and the fourth operation state 2 are alternately repeated a predetermined number of times.

  As described above, with the legs held by the air cell 12, the massage unit 9 is moved forward while projecting, so that the height direction foot is applied to the hip or thigh muscles in a posture in which the knee is bent. It can give a sense of stretching that stretches forward. Also, in the fourth massage operation, by controlling the massage motor M2 based on the width sensor 85, the distance between the left and right treatment elements 62b, 62b is adjusted, and the left and right treatment elements 62b are respectively adjusted to the left and right thighs. It is also possible to bring it into contact properly.

  In the first to fourth massage operations, the massage unit 9 may be moved to the seat portion 3 after being in the protruding position or while advancing. In this case, it is possible to shorten the time until the effect of each massage operation is obtained.
