The part 4 is tilted backward so as to be in a state where it has fallen by a predetermined angle, and the footrest 5 is rotated upward so as to be in a raised state where the user can extend the knee and place the leg part. As a second step, the massage mechanism 8 is moved to the shoulder position based on the detection result of the shoulder position detection sensor 8c. In the present embodiment, as shown in FIG. 9, the massage mechanism 8 is raised from the periphery of the waist to the shoulder.

  As a third step, with the backrest part 4 lying down at a predetermined angle and the massage mechanism 8 positioned at the shoulder position, the heel part air cells a5, a6, the thigh air cell a7, and the upper arm part air cell a3 On the other hand, air is supplied for a predetermined time, and the buttocks air cells a5 and a6, the thigh air cell a7, and the upper arm air cell a3 are expanded. Then, the buttocks are pushed upward in the supine posture and the upper arm is pressed from substantially the front. Accordingly, the upper body is warped backward and the shoulder is pressed against the massage mechanism 8. As a fourth step, the massaging motor M2 and / or the tapping motor M3 are driven to cause the massaging mechanism 8 to knead and / or strike. In the present embodiment, as shown in FIG. 9, only the squeezing operation is performed by moving the treatment elements 8b, 8b that make a pair of left and right close to and away from each other.

  In the third step, at least the buttocks air cells a5 and a6 may be inflated, and the thigh air cell a7 and the upper arm air cell a3 may not be operated or provided. In addition, the reclining operation of the backrest portion 4 to the state where it is lying down by a predetermined angle, the movement of the massage mechanism 8 to the shoulder position, the supply of air to the heel part air cells a5 and a6, and the stagnation operation by the massage mechanism 8 are started simultaneously. Alternatively, the order may be appropriately changed and started. Further, the footrest 4 may remain in the suspended state shown in FIG. 1 without rotating upward.

  INDUSTRIAL APPLICABILITY The present invention can be applied to a chair-type massage machine that gives a sufficient pressing action substantially backward to the user's thigh and can obtain a stretch feeling that attracts the thigh to the chest. it can.
