The protruding members 20a and 20b penetrate the moving base 39 in the plate thickness direction. The moving base 39 can be configured to smoothly move linearly while being guided by the projecting members 20a and 20b.

  FIG. 8 is a view of the massage device 7 as seen from the back side (opposite to the treatment element), and FIG. 9 is a view showing a part of the driving means 11a. 7, 8, and 9, the driving means 11 a includes a motor 41, a rotating shaft 42 that is rotatably supported on the back surface of the base member 29, and a cam 43 that rotates integrally with the rotating shaft 42. The rotating shaft 42 and the cam 43 are configured to be rotationally driven by the rotation of the motor 41. Then, when the rotating cam 43 comes into contact with the contact 44 provided on the back surface 39 a side of the moving base 39, the moving base 39 moves toward and away from the base member 29. The forward / backward driving is performed. The power transmission between the motor 41 and the rotating shaft 42 is performed by a belt. The motor 41 is preferably a geared motor.

5, 6, and 7, the stagnation drive mechanism 11 is provided between the moving base 39 and the second treatment element 2 and between the movement base 39 and the first treatment elements 1 a and 1 b, respectively. The link members 22a and 22b are provided. More specifically, the link member 22b is a straight member on the first treatment element 1a, 1b side, and one end of the link member 22b is pivotally attached to a part of the peripheral edge of the moving base 39. The other end is pivotally attached to the other end of the fixing member 17a that fixes the first treatment elements 1a and 1b.
On the second treatment element 2 side, the link member 22a is a linear member, one end of which is pivotally attached to the moving base 39 side, and the other end is connected to the second treatment element 2. It is pivotally attached to the other end of the fixed member 17b. The link member 22 a is pivotally attached to a rotary link 23 described later, and is swingable with respect to the moving base 39 via the rotary link 23.
As described above, the fixing members 17b and 17a fixing the first and second treatment elements are pivotally attached to the projecting members 20a and 20b projecting from the base member 29 toward the user. At the same time, the link members 22a and 22b on the side of the moving base 39 that is driven forward and backward are also pivoted.

According to the stagnation drive mechanism 11 configured as described above, the moving base 39 can move forward and backward in a straight line toward the user by the driving means 11 a, and the link members 22 a and 22 b are connected to the moving base 39. The advancing and retreating linear motion can be converted into the swinging motion of the first treatment element 1a, 1b and the second treatment element 2.
Furthermore, according to the kneading drive mechanism 11, a plurality of treatment elements can be simultaneously swung by advancing and retreating driving of one moving base 39, and massage by pinching can be performed by these treatment elements. Further, since the forward / backward movement of the moving base 39 is converted into the swing motion of each treatment element via the link members 22a and 22b, the direction of the swing axis of each treatment element (fixing members 17a and 17b) is changed. By doing so, the swinging direction of each treatment element can be set arbitrarily and easily. Furthermore, even if the number of treatment elements is increased from three, power can be obtained from one common moving base 39, so that the structure can be simplified even if the number of treatment elements increases.
Furthermore, each treatment element is supported in a state of being pivotally attached to both the projecting members 20a and 20b and the link members 22a and 22b, and performs a swinging motion, and since the driving means 11a does not have a gear, Unlike the mechanism having the gear, it is possible to prevent the shift of the swing range of the treatment element due to the backlash between the gears.

Furthermore, the massage tool 7 of the present invention is configured so that the first treatment element 1a, 1b and the second treatment element 2 are driven so as to perform a massage motion by pinching as the first treatment element 1a, 1b and the second treatment element 2 approach or separate from each other. In addition to the mechanism 11, a second drive mechanism 12 is provided. This 2nd drive mechanism 12 drives so that the 2nd treatment element 2 may perform more complicated massage exercise | movement other than this approach or separation.
This complicated massage exercise to be performed on the second treatment element 2 by the second drive mechanism 12 may be a kneading operation that rotates the second treatment element 2 along a circular path with respect to the user (human body). it can. Specifically, the protruding member 20a to which the second treatment element 2 is attached at the tip is a rotating shaft, and this kneading operation is a rotation around the axis C2 (FIG. 7) of the rotating shaft 20a. Is obtained from the exercise performed by. According to this configuration, the structure for performing the kneading operation can be simplified. Since the rotation shaft 20a is the protruding member, the rotation shaft 20a is a member extending in the advancing / retreating direction of the moving base 39, and the axis C2 of the rotation shaft 20a and the axis C1 of the base member 29 are parallel to each other. It becomes.
In addition, the circular orbit of the 2nd treatment element 2 has the case of the surroundings of the axis parallel to the reference axis C1 (axis) of a massage machine, and the case of the periphery of the inclined axis | shaft which cross | intersects the said reference axis C1. This is because the center line of the bearing (rolling bearing) 23d is inclined with respect to the axis C1. And when this circular orbit is made around an inclined axis, the distance of the second treatment element 2 to the body of the user can be changed, so the massage force (pressing force) by the second treatment element 2 is changed. Can be made.

As shown in FIG. 7, the rotation shaft 20 a to which the second treatment element 2 is pivotally attached passes through the base member 29 and the moving base 39. The rotation shaft 20a is rotatable with respect to the rolling bearings attached to the base member 29 and the moving base 39, and the rotation shaft 20a is centered on the base member 29. Directional movement is restricted and attached. The movement base 39 is movable in the direction of the axis C2 with respect to the rotation shaft 20a.

The second drive mechanism 12 rotates the bevel gear 48 so that the rotation shaft 20a can rotate. That is, the second drive mechanism 12 is a rotation drive mechanism that rotates the rotation shaft 20a.

  The structure of the second drive mechanism 12 will be further described. The second drive mechanism 12 includes a motor 46 and a rotary shaft 47 that is rotatably supported on the back surface of the base member 29 in FIGS. 7 and 8. The bevel gear 48 is configured to rotate integrally with the rotary shaft 47. Therefore, when the rotation shaft 47 and the bevel gear 48 are driven to rotate by the rotation of the motor 46, the rotation shaft 20a rotates about its axis C2 (rotation axis), and the fixing member 17b is formed on the tip end side of the rotation shaft 20a. The 2nd treatment element 2 attached via is rotated centering on the axial center C2. The motor 46 is preferably a geared motor.

The fixing member 17b that fixes the second treatment element 2 is pivotally attached not only to the rotation shaft 20a but also to the link member 22a that is swingably attached to the moving base 39 as described above. Accordingly, in order to rotate the second treatment element 2 around the axis C2, a rotation link 23 that is rotatable is provided on the moving base 39, and a link member 22a is pivotally attached to the rotation link 23. ing. And the 2nd treatment element 2 and the rotating shaft 20a rotate with these rotation links 23 and the link member 22a. That is, the rotary link 23 moves forward and backward together with the moving base 39, but is connected to the moving base 39 so as to be rotatable relative to the moving base 39 about the axis C2.
The rotation link 23 will be further described. The rotation link 23 includes an attachment portion 23a through which the rotation shaft 20a is inserted, and a pivot attachment portion 23b pivotally attached to the link member 22a. The mounting portion 23a has a cylindrical portion 23c, and is slidable with the rotation shaft 20a on its inner peripheral surface, and a bearing 23d (rolling bearing) is fitted on the outer peripheral surface thereof. In the moving base 39, a bearing hole 39b is formed in a part of a through hole through which the rotation shaft 20a is inserted, and the bearing 23d is fitted in the bearing hole 39b. Further, a slide bush 39e is fitted into a part of the through hole, and the slide bush 39e is slidably rotatable on the rotation shaft 20a, and the rotation shaft 20a is slidably rotatable with respect to the slide bush 39a. It is fitted. Thereby, the rotation link 23 becomes rotatable with respect to the movement base 39 around the rotation shaft 20a (axis C2). And the 2nd treatment element 2 (fixed member 17b) pivotally attached to the autorotation shaft 20a and the pivoting part 23b of the rotation link 23 provided on the movement base 39 are interlockedly connected by the link member 22a. .
