Specifically, the proximal end portion of the extended portion 4 extends from the right end surface of the annular fitting portion 15R so as to protrude outward in the width direction, and the extended distal end is greatly curved toward the front and is oriented after being bent. The inner side in the width direction is gradually curved to extend forward (in FIG. 4, the front end portion of the extended portion 4 protrudes outward in the width direction by a length "X").

As shown in FIG. 3 to FIG. 5 and the like, the distal end side of the extended portion 4 is formed such that the width in the vertical direction is larger than the proximal end side, and the distal end side having the larger width is the treatment body 20 that treats the treatment portion. Further, the distal end portion of the extended portion 4 is disposed to protrude outward in the width direction from the outer bearing portion 12 (in other words, the end portion with respect to the rotating shaft 7).

As shown in FIG. 2, the position of the protective cover 21 corresponding to the treatment body 20 is shown. The corrugated projections 22 and the like are appropriately formed, and the massage effect on the treatment portion such as the waist or the buttocks of the user U can be improved.

Further, although the extension unit 4 on the right side has been described above, the same member as the extension unit 4 on the right side is also disposed on the extension portion 4 on the left side. However, these members are only arranged and operated in a bilaterally symmetrical manner.

Further, when it is desired to obtain a sufficient massage effect in the treatment portion such as the waist or the buttocks, it is preferable to form the extension portion 4 in the front-rear direction so as to cover the buttocks in a wider range. However, the longer the length of the extended portion 4 or the more the front end portion of the extended portion 4 protrudes outward in the width direction, the greater the torsional moment applied to the extended portion 4 during massage, and the following is likely to occur. The deformation is that the extended portion 4 cannot withstand the torsional moment and is excessively expanded in the width direction or the rotating shaft 7 is bent forward.

Therefore, in the massage machine 1 of the present invention, the interposer conversion unit 8 is disposed with the inner bearing portion 11 and the outer bearing portion 12 at a short distance from each other on the left and right sides of the rotary shaft 7 to which the extended portion 4 is attached. Thus, the rotating shaft 7 to which the extended portion 4 is attached is supported with a short span, thereby suppressing deformation of the rotating shaft 7.

Thereby, when the drive unit 2 (electric motor) is driven, the drive shaft of the drive unit 2 rotates, and the rotational drive force is transmitted to the rotary shaft 7 via the worm and the worm wheel 10, thereby rotating the rotary shaft 7. Thereby, when the rotating shaft 7 rotates, the inclined cam surface 14 of the rotating boss portion 13 is rotated about an axis inclined with respect to the rotating shaft 7. Therefore, the annular fitting portion 15 that is externally fitted to the inclined cam surface 14 of the rotary boss portion 13 functions. There is a force that rotates about an axis that is inclined with respect to the rotating shaft 7.

However, since the above-described rotation restricting mechanism 17 is provided in the annular fitting portion 15, and the restricting projection 18 in the rotation restricting mechanism 17 is fitted in the restricting groove 19 provided in the inner wall surface of the rear casing 6, the relative rotation is performed. Since the annular fitting portion 15 does not rotate together with the rotation boss portion 13, the restriction projection 18 is guided in the left-right direction along the direction in which the restriction groove 19 is formed, thereby allowing the annular fitting portion 15 to be engaged. Swing motion in the left and right direction. In other words, when the rotating shaft 7 is rotated, the annular fitting portion 15 is swung in the left-right direction, and the extended portion 4 provided on the outer end surface in the width direction of the annular fitting portion 15 is also moved in the left-right direction. swing.

Further, as described above, since the inclination direction of the inclined cam surface 14 is bilaterally symmetrical with respect to the right and left rotation boss portions 13, the swing direction of the left and right annular fitting portions 15 is also bilaterally symmetrical, so that the left and right extension portions 4 are oriented toward each other. The swinging is performed in the opposite direction from the left and right, and the force in the pressing direction can be intermittently applied to the treatment portion, whereby the treatment portion can be massaged.

Therefore, in the massaging machine 1 of the present invention, it is possible to perform an effective massage from the waist portion of the user U to the treatment portion of the buttocks, in particular, the treatment portion from the side of the waist to the side of the buttocks.

Further, as shown in Fig. 2, the main body portion 3 and the extension portion 4 are covered with a cushioning material such as urethane, and then further on the cushioning material. The cover is provided with a protective cover 21 such as artificial leather. Further, in a portion facing the treatment portion of the user U, in other words, a portion such as the treatment body 20 provided at the distal end of the extension portion 4 is provided with a protrusion or the like, and the massage effect can be promoted.

Further, the massage machine 1 of the present embodiment is a cover structure in which the main body portion 3 and the pair of extension portions 4 and 4 are covered with a cushioning material, and the back side of the cover structure is formed in a U shape. Arc shape.
