BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine for treating the body of a person to be treated.

[0002]

2. Description of the Related Art Recently, chair type massage machines have become widespread. FIG. 15 is a perspective view showing an example of the configuration of this type of massage machine. As shown in FIG. 15, the chair-type massage machine 101 includes a seat portion 102 and a backrest portion 103.
It is mainly composed of and. Armrests 104 are provided on both sides of the seat 102. A massage mechanism (not shown) is provided inside the backrest 103. The user sits on the seat 102, uses the armrest 104 as an arm rest, and uses the massager 101. Further, the lower end of the backrest portion 103 has a seat portion 102.
It is rotatably supported at the rear portion of the backrest 103 so that the backrest portion 103 can be reclined.

[0003]

However, in the conventional massage machine as described above, the armrest portion 104 is used.
In many cases, for example, a treatment device such as a vibrator is not provided, and there is a problem that the arm of the user cannot be treated.

Further, when the backrest 103 is tilted (reclining), the upper body of the person to be treated also tilts accordingly, so that the arm of the person to be treated moves on the armrest 104. . Therefore, even when the armrest 104 is provided with a treatment device such as a vibrator, the treatment area by the treatment device is different from the arm portion of the user before and after tilting the backrest portion 103. Although the treatment device can perform treatment on the arm of the user before the backrest 103 is tilted, the treatment device cannot be performed because the treatment device is separated from the arm of the user after the tilt. There was a problem such as.

There is also a massage machine in which a treatment device that is movable in the front-back direction is provided on the upper surface of the armrest portion 104. In such a massage machine, the treatment device is moved according to the tilt of the backrest 103. Therefore, even if the treatment device can treat substantially the same position of the arm of the user before and after the backrest 103 is tilted, the backrest 103 is tilted when the armrest 104 is short in the front and rear. When the armrest 104 does not have a sufficient length in the rear and the like, the arm of the user does not reach the armrest 10.
There was a case where the armrest 104 could not sufficiently fulfill the role of an arm rest apart from No. 4.

Further, since the armrest portion 104 is generally in the shape of a rod that is long in the front-rear direction and its upper surface is used as an arm rest for the user, a treatment device such as a vibrator is provided in the armrest portion 104. Even in such cases, it is often configured to treat only the lower part of the arm of the user, and most of the arm cannot be treated.

The present invention has been made in view of the above circumstances, and is capable of treating the arm of a user,
Moreover, it is an object of the present invention to provide a massage machine capable of treating a site almost the same as the site before tilting even when the backrest is tilted.

Further, another object of the present invention is to provide a massage machine capable of holding the arm part of the user even when the arm part of the user moves due to tilting of the backrest. To provide.

Still another object of the present invention is to provide a massager capable of treating substantially the entire arm of a user.
