These first massage means and second massage means are driven by a drive unit 35 built in the case body 2.
First, the device configuration of the massage mechanism 10 will be described.
As shown in FIGS. 2 to 4, the massage mechanism 10 includes a pair of left and right massage units 11 a and 11 b and a drive unit 35 that drives the pair of massage units 11 a and 11 b.

In the following, the configuration will be described by focusing on the left massage unit 11a in the drawing.
As shown in FIG. 3 and FIG. 4, the massage part 11 a is disposed below the massage member 12 a provided with the treatment element 14 a and the massage member 12 a, and rotates around an axis centering in the vertical direction. The rotation transmitting member 16a that transmits the rotational driving force of the drive unit 35 to the massage member 12a, and the annular fitting that is externally fitted so that the rotation transmitting member 16a is rotatable and that rotates about the axis that faces in the vertical direction. And a joint member 20a.

Note that the vertical axis of the rotation transmitting member 16a and the vertical axis of the annular fitting member 20a are on the same axis (see the dashed line in FIG. 4).
The massage member 12a is a rectangular plate piece and has a certain height. The length of the massage member 12a in the longitudinal direction is smaller than the outer peripheral diameter of the annular fitting member 20a described below.

On the lower surface side of the massage member 12a, an engaging portion 13, that is, a long groove is formed along the longitudinal direction. The long groove 13 is sized such that an engaging body 20 formed in a rotation transmitting member 16a described below is slidably fitted therein.
Moreover, the guide surface 14 guided by the guide member 22 mentioned below is formed in each of the outer wall of the massage member 12a corresponding to the longitudinal direction one end and the other end of the long groove 13. The pair of guide surfaces 14 are substantially vertical wall surfaces and come into surface contact with the guide wall surface 23 of the guide member 22.

On the other hand, a cylindrical treatment element 15a (protrusion) is provided on the upper surface side of the massage member 12a, and the tip thereof is hemispherical. In addition, about this treatment element 15a, it can arrange | position arbitrarily in a longitudinal direction and the width direction in the upper surface side of the massage member 12a.
In addition, a concave rail 16 whose upper side is open is formed at a position inside the longitudinal end of the massage member 12a. Similarly, an open concave rail 16 is formed at a position inside the other end in the longitudinal direction of the massage member 12a. A convex rail 34 (details will be described later) that hangs on the pressing member 33 is slidably fitted to the concave rail 16.

  The rotation transmitting member 17a is disposed below the massage member 12a, rotates around an axial center in the vertical direction, and transmits the rotational driving force output from the drive unit 35 to the massage member 12a. The rotation transmitting member 17a is a member formed in a disk shape, and a through hole 18 is formed in the center thereof. The rotation shaft 43 of the drive unit 35 is inserted into the through hole 18.

  A long hole 19 communicating with the through hole 18 is formed in the center of the lower surface side of the rotation transmitting member 17a. In the long hole 19, a fixed rod 44 attached to the rotary shaft 43 and having substantially the same size as the long hole 19 is fitted. As a result, the rotation transmitting member 17a is securely fixed to the rotating shaft 43 and is always rotated around the axis (vertical axis) of the rotating shaft 43.

On the other hand, on the upper surface side of the rotation transmission member 17a, the engaging body 20, that is, the pin 20 is provided in a protruding shape at a position away from the rotation axis of the rotation transmission member 17a by a predetermined distance. The pin 20 is formed of a cylindrical member, and rotates so as to circulate around the vertical axis of the rotation transmitting member 17a.
The pin 20 is a member that fits into the long groove 13, and has an outer diameter that is slightly smaller than the length of the long groove 13 in the width direction. As a result, the pin 20 reciprocates (slides) in the longitudinal direction in the long groove 13.

With such a configuration, the rotational driving force output from the drive unit 35 is reliably transmitted to the massage member 12a via the rotation transmission member 17a.
The annular fitting member 21a is formed of an annular member, and is rotatably fitted around the rotation transmitting member 17a and rotates around the vertical axis. The inner peripheral diameter of the annular fitting member 21a is slightly larger than the outer peripheral diameter of the rotation transmitting member 17a. Thereby, the rotation transmission member 17a rotates freely within the annular fitting member 21a.

Note that the upper surface of the rotation transmitting member 17a is positioned substantially flush with or below the upper surface of the annular fitting member 21a because the massage member 12a rotates and slides.
On the upper surface side of the annular fitting member 21a, a pair of guide members 22 for guiding the massage member 12a in the sliding direction are provided in the horizontal direction.
A pair of guide members 22 are provided at opposite positions so as to protrude upward from the outer periphery thereof.

  The guide member 22 is a guide wall surface 23 in which the surface facing the inner side of the annular fitting member 21a faces the substantially vertical direction. The guide wall surface 23 comes into surface contact with either the guide surface 14 formed at one end of the massage member 12a or the guide surface 14 formed at the other end. Further, the surface opposite to the guide wall surface 23 is a wall surface continuous with the outer peripheral wall of the annular fitting member 21a. The guide member 22 is a substantially semicircular member in plan view.

That is, the distance between the pair of guide members 22, that is, the distance between the two guide wall surfaces 23 is substantially the same as the distance from one end of the massage member 12 a to the other end. The pair of guide members 22 guides the massage member 12a slidably between the two guide wall surfaces 23.
By the way, the annular fitting member 21a is a bottomed member in which the outer periphery is formed in an annular shape, but the bottom 24 is provided on the lower side. A through hole 25 through which the rotation shaft 43 passes is formed in the bottom portion 24.

Further, a rotation restricting member 31 constituting the switching means 25 is attached to the lower portion of the bottom portion 24 with a fastener such as a screw.
That is, the massage part 11a stops the rotation of the annular fitting member 21a, and the switching means 26a for freely switching the massage member 12a including the treatment element 15a from the rotational motion to the slide motion and from the slide motion to the rotational motion. Have.

  The switching means 26a is configured to stop the rotation in one direction of the rotation of the annular fitting member 21a and switch the massage member 12a to either the rotational motion or the slide motion. That is, the switching unit 26a is a member that freely rotates the annular fitting member 21a together with the rotation transmitting member 17a or stops the annular fitting member 21a and rotates only the rotation transmitting member 17a.

Specifically, the switching means 26a includes a notch 27a formed in the annular fitting member 21a, and a stopper 30a disposed on the outer periphery of the annular fitting member 21a (the outer wall portion of the gear box 39). And a rotation restricting member 32a for restricting the rotation of the annular fitting member 21a.
The cutout portion 27a is cut out on the outer periphery (wall) of the annular fitting member 21a, and one short side faces a direction along the radially outward direction (an upright side 28). It is an inclined side 29 in which one long side faces a direction intersecting the tangential direction of the circumference (a direction of radiating outward). That is, the notch 27a has a substantially isosceles triangle shape in plan view.

The stopper 30a is a rectangular member attached to the upper surface of the outer wall portion of the gear box 39, and is provided at a position adjacent to the annular fitting member 21a. The stopper 30a is rotatably supported on the upper surface of the outer wall portion of the gear box 39 on one end side around the vertical axis.
On the other end side of the stopper 30a, the corner portion 31a facing the annular fitting member 21a has substantially the same shape as the cutout portion 27a.

  When the annular fitting member 21a rotates in one direction, the stopper 30a causes the corner portion 31a to enter the cutout portion 27a and engage with the upright side 28 (short side). Stop rotation in direction. On the other hand, when the annular fitting member 21a rotates in the reverse direction, the stopper 30a goes out along the inclined side 29 (long side) although the corner portion 31a enters the cutout portion 27. .

The rotation restricting member 32a is a member that separates the annular fitting member 21a from the power transmission path of the driving unit 35 (the path for transmitting the rotational driving force output from the driving unit 35 to the massage member 12a including the treatment element 15a). It is. In the present embodiment, a one-way clutch is employed as the rotation restricting member 32a.
The rotation restricting member 32a transmits or does not transmit power to the annular fitting member 20 by switching the internal gear to meshing or non-meshing according to the rotation direction of the rotating shaft 43, that is, by changing the meshing. Communicate.

That is, the rotation restricting member 32a does not mesh when rotating in one direction among the rotations of the annular fitting member 21a, and the rotational driving force output from the drive unit 35 is not applied to the annular fitting member 21a. Communicate. On the other hand, when the annular fitting member 21a rotates in the reverse direction, the rotation restricting member 32a is engaged and transmits the rotational driving force output from the drive unit 35 to the annular fitting member 21a.

In other words, the switching means 26a causes the massaging member 12a to rotate and move when the stopper 30a is fitted into the notch 27a and the rotation restricting member 32a does not transmit the power of the drive unit 35 to the annular fitting member 21a. To slide movement.
Now, the massage member 12a is pressed from above by the pressing member 33 so as not to fall off from the massage portion 11a and to be slidable.

The pressing member 33 is a semicircular member in plan view and is slightly larger than the guide member 22. The pressing member 33 is attached to the upper surface side of the guide member 22 of the annular fitting member 21a by a fastener such as a screw. The semicircular outer peripheral wall of the attached pressing member 33 is flush with the outer peripheral wall of the annular fitting member 21a.
On the side wall of the pressing member 33 facing the inner side of the annular fitting member 21a, a hanging convex rail 34 is provided. The convex rail 34 is slidably fitted into the concave rail 16 of the massage member 12a. The convex rail 34, the concave rail 16, and the guide wall surface 23 of the guide member 22 face the same direction.

Below the annular fitting members 21a and 21b, a drive unit 35 for driving the massage units 11a and 11b is provided.
The drive unit 35 includes a drive motor 36 that outputs a rotational driving force, and a gear box 39 that decelerates the output rotational driving force to a predetermined speed.
The gear box 39 is a casing that is provided below the annular fitting members 21a and 21b and is formed in a glasses shape in a plan view. Inside the gear box 39, a pair of left and right flat gears 42a, 42b having a rotation axis oriented in the vertical direction are provided. In the present embodiment, the pair of left and right flat gears 42a and 42b has a diameter larger than the outer diameter of the annular fitting members 21a and 21b.

A through hole is formed in the center of each of the spur gears 42a and 42b, and the rotation shafts 43a and 43b are inserted into the through holes. As described above, the rotation shafts 43a and 43b are provided with the fixed rod 44 and the rotation regulating members 32a and 32b below the fixed rod 44, respectively.
For example, the rotation shaft 43a attached to the left spur gear 42a rotates the rotation transmission member 17a disposed above the rotation shaft 17a via the fixed rod 44, and an annular fitting member 21a fitted on the rotation fitting member 21a. It is rotated via a rotation restricting member 32a (one-way clutch).

That is, the vertical axis of the spur gear 42a, the vertical axis of the rotation transmitting member 17a, and the vertical axis of the annular fitting member 21a are coaxial. The right spur gear 42b has the same configuration as the left spur gear 42a.
The pair of left and right flat gears 42a and 42b mesh with each other. The left spur gear 42a meshes with the worm wheel 41 provided on the front side. The worm wheel 41 is in mesh with the worm gear 40 with the axis of rotation directed vertically. The worm gear 40 is attached to the tip of the output shaft 37 of the drive motor 36.

The drive motor 36 is disposed on the front side of the left spur gear 42a, with the output shaft 37 oriented horizontally and rightward. The drive motor 36 has a main body 38 fixed to a gear box 39.
That is, the left spur gear 42a is the driving side, and the right spur gear 42b is the driven side.
As a power transmission path of the drive unit 35, when a rotational driving force is output from the output shaft 37 of the driving motor 36, the rotational driving force is transmitted to the left flat gear 42a via the worm gear 40 and the worm wheel 41. .

  The left spur gear 42a transmits a rotational driving force to the right spur gear 42b, rotates the left rotation transmission member 17a via the rotation shaft 43a, and rotates the left annular fitting member 21a. The left rotation transmission member 17a transmits a rotational driving force to the left massage member 12a via the pin 20 fitted in the long groove 13, and causes the left treatment element 15a to perform a massage operation.

On the other hand, the right spur gear 42b to which the rotational driving force is transmitted rotates the right rotation transmission member 17b and the right annular fitting member 21b via the rotation shaft 43b. The right rotation transmission member 17b transmits a rotational driving force to the right massage member 12b via the pin 20 fitted in the long groove 13, and causes the right treatment element 15b to perform a massage operation.
Next, operation | movement of the massage mechanism 10 explained in full detail above, ie, operation | movement of the massage part by the drive part 35, is demonstrated based on figures.

First, the rotational movement of the massage parts 11a and 11b by the drive part 35 will be described with reference to FIG. The rotational movement of the massage parts 11a and 11b is realized by the first massage means.
That is, the first massaging means rotates the rotation transmitting members 17a and 17b and the annular fitting members 21a and 21b together around the axis by the rotational driving force of the driving unit 35, and the rotation transmitting members 17a and 17b. The massage members 12a and 12b are rotated through the massage member 12a, and the massage part 15a and 15b are given massage massage operations to the treatment part F.

Specifically, as shown in FIG. 5, when the first massaging means outputs a rotational driving force from the output shaft 37 of the drive motor 36, the first massaging means moves the worm wheel 41 meshed with the worm gear 40 via the worm gear 40 in the right direction ( Rotate clockwise. Then, the left spur gear 42a meshing with the worm wheel 41 rotates in the left direction (counterclockwise).
The rotating shaft 43a that rotates together with the left spur gear 42a rotates the rotation transmitting member 17a disposed upward through the fixed rod 44 fitted in the long hole 19 in the left direction. Further, the rotation shaft 43a also rotates the annular fitting member 21a that is externally fitted to the rotation transmitting member 17a via the rotation restricting member 32a (one-way clutch) in the left direction. That is, the left rotation transmission member 17a and the annular fitting member 21a are simultaneously rotated in the same left direction by the rotation shaft 43a.

  The pin 20 provided on the left rotation transmission member 17a slides in the long groove 13 of the massage member 12a and moves to the left end of the long groove 13 by the rotation of the rotation transmission member 17a. Then, the left massage member 12a rotates in the left direction (counterclockwise) at a constant speed. Further, the massage member 12a is fixed so that one end and the other end thereof are not largely moved in the left rotation direction by the guide member 22 and the pressing member 33.

The therapeutic element 15a rotates at a constant speed in the left direction along with the rotation of the massage member 12a. At this time, the treatment element 15a exists at a position on the annular fitting member 21a. That is, the treatment element 15a rotates at a constant speed in the left direction at a position far from the axis of the rotation shaft 43a ((rotation radius (large)).
On the other hand, the right spur gear 42b is rotated in the right direction (clockwise) by the left spur gear 42a on the driving side.

  The rotating shaft 43b that rotates together with the right spur gear 42b rotates the rotation transmitting member 17b disposed upward through the fixed rod 44 fitted in the long hole 19 in the right direction. Further, the rotation shaft 43b also rotates the annular fitting member 21b that is externally fitted to the rotation transmitting member 17b via the rotation restricting member 32b (one-way clutch) in the right direction. That is, the right rotation transmission member 17b and the annular fitting member 21b are simultaneously rotated in the same right direction by the rotation shaft 43b.

  The pin 20 provided on the right rotation transmission member 17b slides in the long groove 13 of the massage member 12b and moves to the right end of the long groove 13 by the rotation of the rotation transmission member 17b. Then, the left massage member 12b rotates in a right direction (clockwise) at a constant speed. Further, the right massage member 12b is fixed so that one end and the other end thereof are not greatly moved in the right rotation direction by the guide member 22 and the pressing member 33.

The treatment element 15b rotates at a constant speed in the right direction along with the rotation of the massage member 12b. At this time, the treatment element 15b exists at a position on the annular fitting member 21b. That is, the treatment element 15b is rotated at a constant speed in the right direction ((rotation radius (large)) at a position away from the axis of the rotation shaft 43b by a predetermined distance.
Next, the sliding movement of the massage unit by the drive unit 35 will be described with reference to FIGS. 6 and 7. The transition from the rotary motion of the massage unit to the slide motion is realized by switching from the first massage means to the second massage means.

  That is, the second massage means stops the rotation of the annular fitting members 21a and 21b by the switching means 26a and 26b, rotates the rotation transmission members 17a and 17b, and rotates the rotation transmission members 17a and 17b. In the long groove 13 (engagement portion), the pin 20 (engagement body) is reciprocated, and the massage members 12a and 12b are slid by the guide of the guide member 22, so that the treatment element 15a, It is set as the structure which provides the expansion | extension massage operation | movement by 15b.

  Specifically, as shown in FIG. 6, when the second massaging means reversely rotates the output shaft 37 of the drive motor 36 and outputs a rotational driving force in a direction opposite to the above-described direction, the worm gear 40 is output. The worm wheel 41 meshing with is rotated leftward (counterclockwise). Then, the left spur gear 42a meshing with the worm wheel 41 rotates in the right direction (clockwise).

  The rotating shaft 43a that rotates together with the left spur gear 42a rotates the rotation transmitting member 17a disposed upward through the fixed rod 44 fitted in the long hole 19 in the right direction. Further, the rotating shaft 43a also rotates the annular fitting member 21a externally fitted to the rotation transmitting member 17a via the rotation regulating member 32a (one-way clutch) (one point in FIGS. 2 and 5). (See dashed arrow).

  At this time, the stopper 30a of the switching means 26a is in contact with the corner portion 31a so as to run on the outer peripheral wall of the annular fitting member 21a, and has a plurality of notches provided on the outer peripheral wall of the annular fitting member 21a. Fit into one of 27a. When the stopper 30a is fitted into the cutout portion 27a, the corner portion 31a comes into surface contact with the upright side 28 where a force is acting in the clockwise direction. At this time, the rotation restricting member 32a does not transmit the rotation of the rotating shaft 43a to the annular fitting member 21a. That is, the torque is released to make the annular fitting member 21a free.

Thus, the engagement of the stopper 30a and the notch 27a and the non-transmission of the rotational driving force by the rotation restricting member 32a, that is, the switching means 26a causes the left annular fitting member 21a to be completely removed from the power transmission path of the driving unit 35. Separated.
Similarly, the right annular fitting member 21b is completely disengaged from the power transmission path of the drive unit 35 by the engagement between the stopper 30b and the notch 27b and the non-transmission of the rotational driving force by the rotation restricting member 32b, that is, the switching means 26b. Disconnected.

Then, as shown in FIG. 7, the pin 20 rotates around the vertical axis of the rotation transmission member 17a by the rotation of the left rotation transmission member 17a. In this case, it slides from one end of the inside to the other end and reciprocates.
For example, as shown in the upper left diagram of FIG. 7, when the pin 20 is located on the rear side and rotates around the vertical axis of the rotation transmitting member 17 a in the right direction (clockwise), in the long groove 13 Will move from the center in the longitudinal direction to one end side.

At this time, the massage member 12a is guided while sliding forward from the rear end side. Thereby, the treatment element 15a will move to the center in the front-back direction from the rear end side.
Then, as shown in the upper right view of FIG. 7, when the pin 20 rotates rightward and is positioned on the right side, the pin 20 moves in the long groove 13 and comes into contact with one end. When the pin 20 comes into contact with one end in the long groove 13, the movement starts to the other end on the opposite side.

At this time, the massage member 12a is guided while sliding from the center in the front-rear direction to the front end side. Thereby, the treatment element 15a will move from the front-back direction center to the forefront end side.
As shown in the lower right diagram of FIG. 7, when the pin 20 rotates rightward and is positioned on the front side, in the long groove 13, the pin 20 moves from the center in the longitudinal direction to the other end side.

At this time, the massage member 12a is guided while sliding backward from the front end side. Thereby, the treatment element 15a will move to the center in the front-back direction from the front end side.
As shown in the lower left diagram of FIG. 7, when the pin 20 rotates rightward and is positioned on the left side, it moves in the long groove 13 and comes into contact with the other end. When the pin 20 comes into contact with the other end in the long groove 13, the movement starts to the one end on the opposite side.

At this time, the massage member 12a is guided while sliding from the center in the front-rear direction to the rearmost side. Thereby, the treatment element 15a moves from the center in the front-rear direction to the rearmost side.
As described above, the massaging member 12a repeats the operations shown in the upper left diagram to the lower left diagram in FIG. It becomes possible to give the extension massage operation by.

Note that the slide motion of the right massage member 12b is also a mirror image of the above-described motion, and a description thereof will be omitted here.
Now, the massage mechanism 10 is provided with a turning radius switching means that can freely change the turning radius of the treatment elements 15a, 15b with respect to the vertical axis of the rotation transmitting members 17a, 17b.

The operation of the turning radius switching means will be described with reference to FIG.
As a configuration of the turning radius switching means, for example, the massaging members 12a and 12b are stopped at arbitrary positions while the massaging members 12a and 12b are slid by the second massaging means. And it switches from a 2nd massage means to a 1st massage means.

Then, the treatment elements 15a and 15b perform massage massage operation with a rotational motion different from the rotational motion described in the first massage means, that is, a trajectory having a rotational radius different from the rotational radius described above. .
Specifically, when the massage members 12a and 12b are slid by the second massage means, the turning radius switching means stops the massage members 12a and 12b on the rotation transmission members 17a and 17b, for example. In the example of FIG. 8, the massage members 12a and 12b are stopped above the vertical axis.

Then, the rotation of the output shaft 37 of the drive motor 36 is rotated in the reverse direction to switch from the second massage means to the first massage means.
The worm wheel 41 rotates in the right direction (clockwise), and the left spur gear 42a meshed with the worm wheel 41 rotates in the left direction (counterclockwise). As described above, the left rotation transmission member 17a rotates to the left by the fixed rod 44 fitted in the long hole 19, and the gear in the one-way clutch (rotation restricting member 32a) meshes with the left rotation. The annular fitting member 21a fitted on the transmission member 17a also rotates in the left direction at the same time. The left massage member 12a rotates in the left direction by the rotation of the left rotation transmission member 17a.

Then, the treatment element 15a rotates with the rotation of the left massage member 12a along the orbit having a rotation radius smaller than that described above.
Note that the rotational movement of the right treatment element 15b is a mirror image of the rotation movement of the left treatment element 14a, and a description thereof will be omitted here.
By the way, the turning radius switching means may be controlled by a control unit for controlling the massage operation.

For example, since the size of the foot width and the like varies from user to user, a plurality of rotation radii corresponding to the size of the foot width and the like are set in advance. As a specific example, when the leg width is large, the radius of rotation of the treatment elements 15a and 15b is set (large), and when the leg width is small, the radius of rotation of the therapy elements 15a and 15b is set (small).
The control unit may automatically switch the setting of the radius of rotation of the treatment elements 15a and 15b when the user arbitrarily operates a switch or the like of the operation unit 5.

Further, the positions of the treatment elements 15a and 15b that are in contact with the treatment part F (the sole) are automatically detected, and the control unit automatically switches the rotation radius of the treatment elements 15a and 15b based on the detected signals. Also good.
Now, the massage machine 1 of the present invention is provided with a third massage means for moving the treatment elements 15a, 15b in the vertical direction and applying a pressing massage operation to the treatment portion F.

The up and down movement of the massage part by the third massage means will be described with reference to FIGS.

The gear box 49 is provided on the rear side of the vertical drive motor 46 and has a casing that is long in the vertical direction. An output shaft 48 of the vertical drive motor 46 is inserted on the upper side of the gear box 49. Further, the right end portion of the rotating shaft 50 is inserted on the lower side of the gear box 49.

The rotating shaft 50 is a long bar 57 and is provided on the lower side of the case body 2 and on the rear side of the massage mechanism 10. Further, the rotating shaft 50 is arranged so as to be spanned in the horizontal direction and in the left-right direction, and both ends thereof are rotatably supported by support bases 60 provided at both ends in the left-right direction of the case body 2. Yes.
The output shaft 48 and the rotary shaft 50 of the vertical drive motor 46 are arranged so as to have a predetermined interval in the vertical direction, and the right end portion of the rotary shaft 50 and the output shaft 48 are substantially orthogonal in a plan view.

Conversion parts 51 a and 51 b are attached to the left and right ends of the rotating shaft 50.
The conversion parts 51a and 51b have eccentric boss parts 52a and 52b that externally fit the rotating shaft 50, and link members 53a and 53b that externally fit the eccentric boss part 52.
For example, the left eccentric boss portion 52a is formed of a disk-like member, and a through hole into which the rotary shaft 50 is inserted is formed. The inner diameter of the through hole is substantially the same as the outer diameter of the rotary shaft 50. A long hole (both not shown) for fitting a fixing pin attached to the rotary shaft 50 is provided around the through hole. When the fixing pin is engaged with the elongated hole, the eccentric boss portion 52a and the rotation shaft 50 are relatively rotated.

Further, the through hole into which the rotating shaft 50 is inserted is provided so that the axis is located away from the center of the circle of the eccentric boss portion 52a. Thus, since the rotation center of the eccentric boss portion 52a is different from the center of the circle, when the rotation shaft 50 rotates, the eccentric boss portion 52a rotates eccentrically.
The link member 53a is formed of a plate-like member, and an annular fitting portion 54 is formed on one end side. The annular fitting portion 54 externally fits the eccentric boss portion 52a so that the inner peripheral diameter is substantially the same as the outer peripheral diameter of the eccentric boss portion 52a.

On the other hand, a support portion 55 is provided on the other end side of the link member 53a to support the entire massage mechanism 10 so as to be movable in the vertical direction.
The support portion 55 is a ring-shaped member in which a through hole is formed, and a bearing 56 is inserted into the through hole. The bearing 56 has one end of a bar 57 inserted on the inner peripheral side. The bar 57 has a horizontal axis and a horizontal direction, and the other end side rotatably supports the massage mechanism 10.

When the conversion portion 51a is viewed from the side, the shaft center of the through hole of the eccentric boss portion 52a (the rotation shaft center of the rotation shaft 50) is positioned below the bar 57 inserted into the support portion 55 via the bearing 56. doing.
The configuration of the right conversion unit 51b is the same as that of the left conversion unit 51a.

The base 61 provided in the case body 2 is provided with a rod-shaped guide post 58 that guides the entire massage mechanism 10 in the vertical direction. The massage mechanism 10 is provided with a guide hole 59 into which the guide post 58 is inserted.
With this configuration, the rotational driving force output from the output shaft 48 of the vertical drive motor 46 is rotated downwardly from the upper side of the gear box 49 via the built-in gear. 50.

The converters 51a and 51b convert the rotational driving force transmitted by the rotary shaft 50 into vertical motion.
As shown in FIG. 9, when the eccentric bosses 52 a and 52 b rotate eccentrically by the rotation of the rotating shaft 50, the support portions 55 of the link members 53 a and 53 b rotate upward around the axis of the rotating shaft 50. At this time, each support portion 55 moves the entire massage mechanism 10 upward by means of the bar 57 via the bearing 56. The massage mechanism 10 is guided upward by the guide post 58 inserted in the guide hole 59.

  As shown in FIG. 10, when the eccentric boss portions 52 a and 52 b are further eccentrically rotated by the rotation of the rotation shaft 50, the support portions 55 of the link members 53 a and 53 b are rotated downward around the axis of the rotation shaft 50. become. At this time, each support portion 55 moves the entire massage mechanism 10 downward. The massage mechanism 10 is guided downward by the guide post 58.

By repeating such a vertical movement of the entire massage mechanism 10, the treatment elements 15 a and 15 b move in the vertical direction, and a pressure massage operation can be applied to the treatment part F.
In addition, in the massage machine 1 of the present invention, the plate member 6 disposed on the upper surface of the case body 2 is configured to vibrate so that vibration massage can be applied to the treatment portion F. ing.
