When the user sits on the chair (11) and selects, for example, a rolling massage (step 1), the above-mentioned shoulder position detection operation is executed to detect the shoulder position of the user (step 2), It is stored in the memory of the microcomputer (101). Then, a rolling massage is given to the user (step 3).

During the massaging operation, when the user presses the reclining switch of the remote controller (102) "start" or "down" (step 4), the reclining motor (9)
1) rotates and the angle of the backrest (13) changes. At this time, the number of rotations of the reclining motor (91) (the number of hall element output pulses) is transmitted from the motor detection circuit (108) to the microcomputer (101), and the number of rotations is counted by the microcomputer (101).
The correction amount is determined. Further, it is determined from the rotation direction of the motor (91) whether to move the shoulder position to the upper side or the lower side (step 5). A new shoulder position is calculated from the correction amount and the correction direction of the shoulder position, and is overwritten in the memory of the microcomputer (101), the change of the shoulder position is completed (step 6), and massage is continuously performed based on the new shoulder position. (Step 3).

As described above, since the shoulder position is changed according to the operation of the reclining mechanism (90), a desired portion of the user can be massaged, and the massage effect does not decrease, Also, no discomfort is felt.

Other Embodiments In the above embodiments, the shoulder position is changed based on the rotation speed of the reclining motor (91), but an appropriate correction amount is set based on the rotation time and the rotation direction of the motor (91).
