However, the massage mechanism 7 of the present embodiment is provided with a tapping massage means that uses the first treatment member 13 of the first arm 11 and the second treatment member 14 of the second arm 12 to perform a tapping massage operation on the treatment part.

Specifically, as shown in FIG. 4, the tapping massage means includes a tapping driving motor 42 arranged on the rear side of the massage mechanism 7, a tapping driving shaft 41 provided above the tapping driving motor 42, and embedded in the tapping. The connecting arm 22 of the driving shaft 41 is knocked; and the protruding piece 21 formed on the massage member 10 and connected to the connecting arm 22.

The knock driving shaft 41 is a shaft mounted in the left-right direction, and can be rotated by the knock driving motor 42. The knock driving motor 42 is arranged so that the output shaft faces upward. A knock driving gear box 43 is disposed above the knock driving motor 42. The output shaft system of the knock driving motor 42 is inserted into the knock driving gear box 43, and the knock driving gear box 43 is provided with a knock driving shaft 41 in a penetrating manner.

Cylindrical tapping bosses 44 are attached to both ends of the tapping drive shaft 41 in a state eccentric to the axis of the tapping drive shaft 41. The tapping boss portion 44 is rotatably loosely fitted into the third annular fitting portion 24 provided at the base end portion of the connecting arm 22, and is configured to fit into the tapping drive shaft 41.

In other words, when the knock driving shaft 41 is rotated by the knock driving motor 42, the knock projection base 44 mounted in an eccentric state rotates eccentrically about the axis of the knock driving shaft 41, and is loosely fitted into the knock. Since the third annular fitting portion 24 of the boss portion 44 also rotates eccentrically, the connecting arm 22 swings in the vertical direction.

Then, the eccentric rotation of the base end portion side of the massaging member 10, that is, the third annular fitting portion 24 which is coupled to the connecting arm 22, is repeatedly rotated to repeat the normal rotation and the reverse rotation around the axis of the rotation shaft 17, so that the first The first treatment element 13 of the one arm 11 and the second treatment element 14 of the second arm 12 alternately perform tapping on the treatment unit to give a tapping massage action.

According to the massage mechanism 7 of the present invention described above, the treatment part can be inserted between the grasping treatment part 28 and the first treatment part 13 opposite to the shoulder part, so as to realize the shoulder portion as if the person applied the technique of grasping the shoulder Kneading action (grabbing massage) required.

Furthermore, in the present invention, since the first arm 11 provided with the first treatment member 13 and the grasping arm 27 provided with the grasping treatment member 28 can perform a stable and smooth grasping massage operation, the treatment section is not subjected to severe Pressed. In addition, the grasping treatment member 28 provided at the front end of the grasping arm 27 of the present embodiment slides closely along a housing (not shown) that covers the pressing-grip driving motor 25 and the like ( Performing circular arc motion), so the disadvantages of the object being caught in the grasping treatment member 28 and the casing (not shown) will not occur.

In addition, each embodiment disclosed in this specification should be considered as illustrative rather than restrictive in all respects. In particular, in the embodiments disclosed in this specification, matters that are not explicitly disclosed, such as operating conditions or operating conditions, various parameters, the size, weight, and volume of the structure, have not escaped the scope generally implemented by those in the industry. As long as it is a value that can be easily conceived by a general operator, it is adopted.

For example, in this specification, the chair type massage machine 1 is described as an example, but the massage mechanism 7 may be mounted on a sheet type massage machine, a seat type massage machine, or a handheld type massage machine.
