Embodiments of the present invention will be described below. 1 is a schematic side view, and FIG. 2 is a partially enlarged side view.

In the massage machine A, the backrest 2 is connected to the seat 1 so as to be able to turn around the pivot shaft 7 and the electric telescopic actuator 8 is connected. The backrest 2 has a reclining function of rotating the backrest electrically. or,
The holder 9 holding the pivot shaft 7 holds the backrest 2 so as to be able to move up and down. Rack gear 10 in holder 9
However, a pinion gear 11 is provided on the backrest 2 side,
By operating the operation device 12, the pinion gear 11 is driven and rotated, so that the backrest 2 can be moved up and down with respect to the seat 1. As described above, the structure for raising and lowering the backrest 2 with respect to the seat 1 is collectively referred to as an elevating mechanism 5, but the structure can be variously changed.

A guide means is provided inside the backrest 2 so that a drive unit 13 for driving the treatment element 3 such as rotation can be driven and moved along the backrest 2 by the guide means. The backrest portion 2 has a constricted portion 4 for allowing the treatment element 3 to reach the front of the shoulder when the curved surface of the back of the human body is fitted. The drive of the treatment element 3 and the configuration of the drive unit 13 and the like are well known, for example, in Japanese Patent Publication No. 2-49741.

According to such a structure, the pinion gear 11 of the elevating mechanism 5 is driven and rotated by the operation of the operating device 12, so that the backrest 2 can be moved up and down with respect to the holder 9 on the seat 1 side. It is possible, seat 1
When the user sits in a predetermined sitting position, the constricted portion 4 can be positioned at the position of the shoulder. In this manner, the treatment element 3 can be satisfactorily acted on the shoulder in the constricted portion 4 without re-sitting any person.

FIG. 3 is a block circuit diagram showing another embodiment. In the present embodiment, a pressure detector 6 for detecting the pressure applied to the treatment element 3 is provided on a support portion for supporting the treatment element 3, for example. The height of the backrest 2 is controlled based on the detection result of the pressure detection unit 6, and the constriction 4
Is provided with a control unit 14 for performing positioning.

In the present embodiment, the pressure applied to the moving treatment element 3 is detected by the pressure detection section 6, and the pressure is detected to be substantially zero, so that it is regarded that the position of the shoulder has been detected. The height of the backrest 2 is adjusted by transmitting a control signal from the control unit 14 based on the result, and the constriction 4 is moved to the position of the shoulder of a person having a different physique, and the constriction of the backrest 2 is adjusted. The position 4 is precisely adjusted to the position of the user's shoulder.
