It has become. Further, even if the buttocks strongly hit the massaging device 8 and the massaging device 8 is strongly pressed downward, the connection arm 27 only swings downward so that the buttocks The pressing force from the spring is absorbed by the elastic force of the spring member, and can be transmitted to the rotating shaft 11 or the like to break the massage mechanism 3. In addition, the connecting arm 27 always faces upward by the biasing force of the spring member, and the massage treatment element 8 always fits in the buttocks, so that it is possible to provide a comfortable massage.

At the tip of the connecting arm 27 (each of the upper end and the lower end of the massaging body 12), a massage treatment device 8 is attached which contacts the buttocks and applies a massage. Although various forms can be adopted as the form of the massaging treatment element 8, in the case of the present embodiment, the massaging treatment element 8 is in a ball shape. By adopting such a ball-shaped massaging treatment element 8, the massaging treatment element 8 can contact the buttocks in a wide area, and it is possible to apply a suitable massaging massage.

As shown in FIGS. 3 to 5, the pressing massage mechanism 3b has a pressing massage body 48 that presses the treatment portion of the user M from the outside in the width direction. Further, the pressing massage mechanism 3 b has a pressing massage conversion unit 49 that converts the rotational motion of the rotating shaft 11 described above into translational motion along the left-right direction and transmits the translation motion to the pair of pressing massage bodies 48. The pressing massage body 48 and the pressing massage conversion unit 49 are provided on the further left side of the left-hand massage body 12 and further on the right side of the right-hand massage body 12, and are provided in a pair. Specifically, the pressure massage conversion unit 49 has the rotary shaft 11 between the first bearing portion 14a and the second bearing portion 14b described above, more precisely, the stagnation inclined boss portion 21 and the second bearing portion 14b. Are respectively provided on the rotary shafts 11 between them. The above-described pressing massage body 48 is disposed in each pressing massage conversion unit 49 so as to extend upward.

Next, the pressing massage body 48 and the pressing massage conversion unit 49 provided in the pressing massage mechanism 3b of the buttocks massage machine 1 of the present embodiment will be described.
The pressing massage body 48 is a rod-like member extending so as to stand upward from the lower side. The tip (upper end side) of the pressure massage body 48 is expanded in an oval shape (a bowl shape) whose major axis is directed in the front and rear direction, and the pressure massage body 48 is attached so that the expanded portion in the oval shape faces inward in the width direction. It is possible to effectively press massage the user M's treatment section (the waist to the side of the thigh) over a wide area.

In addition, even if the tip of the pressing massage body 48 is formed by using a synthetic resin material such as urethane foam having a part rich in elasticity so that the tip can contact with the treatment part with a soft contact feeling. good. Further, on the lower end side of the pressing massage body 48, a pressing annular fitting portion of a pressing massage converting portion 49 described later is disposed, and externally fitted to the pressing massage converting portion 49 via the pressing annular fitting portion. Can be input while converting the rotational driving force of the rotating shaft 11.

The pressure massage conversion unit 49 is attached with its axis directed in a direction inclined with respect to the axis of the rotary shaft 11 as with the stagnation tilt boss portion 21 and has a cam surface formed on the outer peripheral surface. The pressing massaging body 48 is rotated as the rotary shaft 11 rotates, with the portion 50, the pressing annular fitting portion provided at the base end of the pressing massaging body 48 and fitted into the cam surface of the pressing inclined boss portion 50. And a pressure restricting portion 51 which restricts movement.

The pressing and inclined boss 50 is a member formed in a cylindrical shape like the stagnation and inclined boss 21 and is attached to the rotating shaft 11 so that the axis is in a direction inclined with respect to the rotating shaft 11. An endless circular orbit (cam surface) is formed on the outer peripheral surface of the pressing inclined boss 50 around an axis which is inclined with respect to the rotating shaft 11. The cam surface of the pressing inclined boss 50 is formed The pressing annular fitting portion of the pressing massaging body 48 is slidably fitted outside via a bearing.

Further, the cam surfaces of the above-described pressing and tilting bosses 50 are opposite in the direction of tilting with respect to the axial center of the rotation shaft 11 between the pressing and pressing bosses 50 on the left and the pressing and tilting bosses 50 on the right . For example, when the cam surface of the left pressure inclined boss 50 is inclined upward to the right, the cam surface of the right pressure inclined boss 50 is inclined upward to the left. As described above, assuming that the inclination direction of the cam surface of the pressing inclined boss portion 50 is opposite on the left and right, the pressing massage body 48 on the right side is the left side when the pressing massage body 48 on the left side swings to the right. When the left side pressing massage body 48 swings to the left side, the right side pressing massage body 48 swings to the right side to make the left and right side pressing massage bodies 48 approach or separate from each other It is possible to operate to

Further, in the massaging mechanism 3 of the first embodiment, the inclination direction of the cam surface of the pressure inclination boss portion 50 is the same as the inclination direction of the cam surface of the stagnation inclination boss portion 21. However, the inclining direction of the cam surface of the pressure inclining boss portion 50 provided in the massage mechanism 3 of the present invention may not be the same inclining direction as the cam surface of the stagnation inclined boss portion 21. If the cam surface of the pressing and tilting boss portion 50 is tilted in a direction different from the rubbing and tilting boss portion 21, it is possible to swing the pressing and massage body 48 with a phase difference with respect to the swinging motion of the massage body 12. It is because it becomes possible to give a user various massage feelings by the massage mechanism 3.

The pressing annular fitting portion is a member which is formed on the base end side (lower end side) of the pressing massaging body 48 and which has a ring shape in a side view as viewed from the outside in the left-right direction. That is, the center of the pressing annular fitting portion is formed in the shape of a round hole penetrating in the left and right direction, and the cam surface of the pressing inclined boss 50 is fitted into the portion formed in the round hole The rotary motion of the rotary shaft 11 is converted into a translational motion (rocking motion) along the right and left direction of the pressing mass body 48. In other words, the pressing annular fitting portion is rotatable relative to the pressing and tilting boss portion 50, and the movement direction can be changed by restricting the rotation by the pressing restricting portion 51 described later.

The pressure regulating portion 51 is a member that regulates rotation of the pressure ring fitting portion with respect to the pressure inclined boss portion 50, and is provided so as to project downward from the base end side of the pressure massaging body 48 The pressure regulation pin 52 and the pressure regulation groove 53 which regulates rotation of the pressure massage body 48 when the pressure regulation pin 52 is fitted. Specifically, the pressing restriction pin 52 protrudes downward from the proximal end side of the pressing massage body 48.

Furthermore, the pressure regulating groove 53 is a member that regulates the rotation of the pressure massaging body 48 by engaging with the pressure regulating pin 52 described above, and in the present embodiment, in the base 13 below the rotary shaft 11, left and right. The base 13 is formed to extend vertically along the direction. The groove width of the pressure restricting groove 53 is slightly larger than the outer diameter of the pressure restricting pin 52, and can be guided in a state in which the pressure restricting pin 52 is inserted along the lateral direction in which the pressure restricting groove 53 is formed. It has become.

On the other hand, the pressure restricting groove 53 restricts the movement of the inserted pressure restricting pin 52 in the vertical direction and the longitudinal direction. That is, in the pressure regulating portion 51, the rotation of the pressure inclined boss portion 50 is regulated by inserting the pressure regulating pin 52 into the pressure regulating groove 53, and the distal end side of the pressure massaging body 48 is in the lateral direction centering on the proximal end. Only the pressure massage body 48 can perform pressure massage.

That is, in the buttocks massage machine 1 provided with the above-described pressing massage mechanism 3b, pressing massage on the treatment part can be performed by causing the left and right pressing massage bodies 48 to approach or separate from each other. Therefore, it is possible to perform not only the massaging massage by the massaging mechanism 3a but also the pressure massaging by the pressure massaging mechanism 3b with respect to the treatment section including at least the buttocks of the user.

By the way, in the buttocks massaging machine 1 provided with the above-mentioned pressing massage mechanism 3b, the size of the buttocks of the user M who is going to receive treatment is not constant. Therefore, for example, in the case where the attachment interval of the left and right pressing massage members is set narrow in order to enable a suitable massage for the user having a small buttock size, the pressure is applied to the user having a large buttock size. The pressure exerted by the massager may be too great and in some cases may cause discomfort.

In addition, if the attachment interval between the left and right pressing massage members 48 is too wide, for users with small buttocks, the pressing force by the pressing massage body 48 becomes too weak, and in some cases a satisfactory feeling of massage can not be obtained. Is also conceivable.
Therefore, the buttocks massaging machine 1 according to the first embodiment is provided with a horizontal movement mechanism 60 (in other words, a width adjusting mechanism) capable of adjusting the attachment intervals of the left and right pressing massage members 48 according to the size of the buttocks of the user. It is done. If such a horizontal movement mechanism 60 is provided, the distance between the left and right pressing massage members 48 can be adjusted in multiple steps from wide to narrow ones, and the user with a small buttock size is small. Also, the convenience is excellent, and it is also possible to impart a good massage feeling.
