Are arranged between the erection positions of the acupressure shafts 43, 43, and the gaps between the acupressure shafts 43, 43 are filled with these spacers 48, 48,.
[0038]
The arrangement of the spacers 48, 48,... Is, for example, similar to the screw bosses 40c, 40c,. It can be realized by fixing it to the supporting flange 42 with a screw. Also, the radial position of the spacers 48, 48 ... is set inside the circumference of the erection of the acupressure shafts 43, 43 ... like the spacer projections 47, 47 ... Has not been impaired.
[0039]
Further, the cross-sectional shape of the spacers 48, 48 ... is not limited to the rectangular tube shape shown in the figure, but may be an appropriate cross-sectional shape such as a circle, an ellipse, or a triangle. It is desirable to have a flat surface or a curved surface so that there is no discomfort at the time of contact with a treatment site such as a calf.
[0040]
【The invention's effect】
As described in detail above, in the massage machine according to the present invention, spacers are respectively arranged between a plurality of acupressure shafts which are erected and supported between a pair of support flanges on both sides of the acupressure roller, and these spacers are used between these acupressure shafts. Since the formed gap is filled, there is no possibility that the treatment site is pinched in the gap during the acupressure massage performed by pressing the treatment site against the peripheral surface of the acupressure roller, and the driving of the acupressure roller is prevented. The load on the system can be reduced and safe use is possible.
[0041]
In addition, a pair of support flanges are formed on both sides of the support cylinder that rotates around the axis, and a part of the outer periphery of the support cylinder is protruded radially outward to integrally form a spacer that fills between the acupressure axes. The above-described effects can be obtained without adding any extra parts.
[0042]
In addition, since the spacer is disposed at a position radially inward of the support cylinder from the position at which the acupressure shaft is erected, the spacer abuts the treatment site pressed against the peripheral surface of the acupressure roller during normal acupressure massage. Therefore, the good massage feeling obtained by the acupressure projections provided on the acupressure shaft is not impaired.
[0043]
Furthermore, the present invention is excellent in that the number of parts and the number of assembling steps can be reduced because the supporting cylinder of the acupressure roller is constituted by two members, a cylindrical body integrally formed with one supporting flange and the other supporting flange. It works.
