In the chair-type massage machine proposed in Patent Document 1, the forearm treatment part cannot perform treatment on the forearm of the person to be treated unless the person to be treated puts the forearm on the armrest part, so that the elbow joint of the person to be treated cannot be treated. The forearm treatment unit can perform treatment on the forearm of the patient only when the chair is bent. That is, in the chair-type massage machine proposed in Patent Document 1, the forearm treatment unit performs treatment on the forearm of the treated person with the elbow joint of the treated person extended (the arm is relaxed). I can't.

Further, when the reclining function is added to the chair-type massage machine proposed in Patent Document 1, the forearm of the person to be treated moves backward with respect to the seat part and the armrest part when the backrest part is tilted, so that the treatment is performed. The treatment position for the person's forearm shifts to the wrist side.

The chair-type massage machine proposed in Patent Document 2 can alleviate the above-mentioned deviation by a mechanism that links the tilting of the backrest portion and the backward movement of the forearm treatment portion. However, since the mechanism for linking the tilting of the backrest portion and the backward movement of the forearm treatment portion has a complicated structure, it becomes a factor that significantly increases the weight and cost of the massage machine.

In view of the above situation, it is an object of the present invention to provide a chair-type massage machine capable of performing treatment on the forearm of the treated person with the elbow joint of the treated person extended.

The chair-type massage machine disclosed in the present specification includes a seat portion, a backrest portion capable of tilting backward of the seat portion, and a forearm treatment portion for treating the forearm of the person to be treated. The forearm treatment portion has a configuration (first configuration) attached to the left and right side surfaces of the backrest portion.

In the chair-type massage machine having the first configuration, when the backrest portion tilts backward of the seat portion, the relative position between the backrest portion and the forearm treatment portion can be fixed (second). The configuration of) may be used.

The chair-type massage machine having the first or second configuration may be configured to include a first adjusting portion (third configuration) capable of adjusting the longitudinal position of the forearm treatment portion with respect to the backrest portion.

Even if the chair-type massage machine having any of the first to third configurations is provided with a second adjusting portion capable of adjusting the lateral position of the forearm treatment portion with respect to the backrest portion (fourth configuration). Good.

The chair-type massage machine having any of the first to fourth configurations includes a third adjusting portion capable of adjusting the predetermined direction position of the forearm treatment portion with respect to the backrest portion, and the predetermined direction is the left-right direction and the said. A configuration (fifth configuration) that is perpendicular to the longitudinal direction of the forearm treatment portion may be used.

The chair-type massage machine having any of the first to fifth configurations may be configured to include armrests arranged above the left and right sides of the seat (sixth configuration).

In the chair-type massage machine having any of the first to sixth configurations, the backrest is in a direction from the ventral side to the back side of the patient while the patient is leaning against the backrest. The surface of the part where the back of the patient is in contact and the surface of the forearm treatment part where the back of the patient is in contact are lined up in the same row, or the surface of the backrest where the back of the patient is in contact. The forearm treatment unit may be arranged in the order of the surfaces in contact with the back side of the forearm of the person to be treated (seventh configuration).

In the chair-type massage machine having any of the first to seventh configurations, the backrest portion is a first portion to which the forearm treatment portion is attached to both left and right side surfaces, and a second portion located above the first portion.
