2. Description of the Related Art As a massage machine of this kind, a housing having an opening, a drive shaft rotatably mounted in the housing, and a drive shaft located around the drive shaft and corresponding to the opening. And a pair of left and right fir rollers connected to the drive shaft so as to incline in opposite directions with respect to the axis of the drive shaft. (For example, Japanese Utility Model Laid-Open No. 2-109628, Japanese Patent Publication No. 4-783)
No. 07 gazette).

[0003] In this conventional roller massage machine, usually, a large number of rolling bodies are arranged on both sides in the axial direction of a drive shaft, and a pair of left and right fir rollers are arranged at a central portion of the drive shaft. Rolling massage can be performed by placing the affected part such as calf, sole of the foot or neck on a rolling body, and fir massage can be performed by sandwiching the affected part between a pair of left and right fir rollers. Has become.

[0004]

In the above-mentioned conventional roller massage machine, the rolling body and the fir roller are merely arranged separately in the axial direction of the drive shaft, so that either the rolling massage or the fir massage is selectively performed. It is possible to apply other massage effects to the affected area while performing those massages,
For this reason, there is a disadvantage that a composite massage effect cannot be obtained.

For example, in the case of rolling massage in which the rolling body strokes the affected part in one direction, it is preferable that the affected part be stroked in the other direction at the same time, because the promotion of blood circulation in the affected part increases. You can't do a complex massage in the sense. In addition, in the case of a fir massage in which a pair of left and right fir rollers rub and loosen the affected part, if the affected part can be stroked to the left and right at the same time, the effect of rubbing and loosening the affected part is promoted, which is preferable. Can not.

[0006] In view of such circumstances, an object of the present invention is to improve the massage effect of a rolling massage or a fir massage by enabling other appropriate massage exercises to be added during the massage.

[0007]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is,
The present invention provides a housing having an opening, a drive shaft rotatably mounted in the housing, and a pair of left and right connected to the drive shaft so as to be inclined in opposite directions with respect to the axis of the drive shaft. A rolling massage machine comprising: a pair of left and right fir rollers that move in the axial direction by rotation of the drive shaft.
An auxiliary massage means having a massage member for stroking the affected part at the same time as the massage massage is provided between the pair of left and right fir rollers.

In this case, since the massage member moves in the axial direction of the drive shaft between the pair of left and right fir rollers,
At the same time as the pair of left and right fir rollers rub and loosen the affected part, the affected part is rubbed left and right (in the axial direction) by the massage member, and the effect of rubbing and loosening the affected part can be increased. In the present invention described above, a number of rolling bodies rotating with the drive shaft may be arranged around the same drive shaft and on both axial sides, and a pair of left and right fir rollers may be arranged at the center of the drive shaft. Then, the above-mentioned composite fir massage and rolling massage can be selectively performed.

The present invention also provides a housing having an opening, a drive shaft rotatably mounted in the housing, and a drive shaft rotatable with the drive shaft around the drive shaft and at a position corresponding to the opening. And a rolling portion having a large number of rolling bodies provided so as to perform the rolling by the rolling body by moving in the axial direction by the rotation of the drive shaft.
An auxiliary massage means having a massage member for stroking the affected part at the same time as the massage is provided near the rolling part.

In this case, since the massage member moves in the axial direction of the drive shaft in the vicinity of the rolling portion, a large number of rolling members constituting the rolling portion stroke the affected portion in the circumferential direction, and at the same time, the affected portion is moved by the massage member. As a result, the patient is stroked left and right (in the axial direction), which can promote blood circulation in the affected part. In the present invention, the auxiliary massaging means is, specifically, a feed screw member which is coaxially fixed in the middle of the drive shaft and has a spiral and endless cam groove on the outer periphery, and a shaft of the drive shaft. It can be constituted by a slider provided movably in the center direction and having a cam projection fitted into the cam groove, and a massage member connected to the slider.

In this case, since the cam projection of the slider is fitted into the spiral and endless cam groove, the rotational movement of the feed screw member is converted into the axial movement of the slider, and the massage member is driven by the shaft of the drive shaft. It will reciprocate in the direction of the center. Further, as the auxiliary massaging means, if a slider having a guide mechanism that allows the slider to move in the axial direction while restricting the slider from rotating together with the feed screw member is employed, the slider becomes Since the slider does not rotate together with the member, the slider can be reliably reciprocated in the axial direction.
