242b, 245b being provided on one side of the massage head mounting member 220.

The cam coupling member 247 has a substantially rectangular plate shape, and a cam coupling hole into which the kneading eccentric cam 242a is inserted and coupled is formed at one side, and as shown in fig. 9A and 9B, when the kneading shaft 242 rotates, the kneading eccentric cam 242a swings left and right while reciprocating the massage head holder 248 and the massage head 249 left and right. At this time, since one end of the cam coupling member 247 is rotatably connected to the pin connection plate 246b that beats the eccentric cam 245a through the hinge pin 247a, the cam coupling member 247 can swing left and right.

In addition, when the tapping shaft 245 is rotated by the tapping motion motor 244, as shown in fig. 10A and 10B, the cam coupling member 247 vibrates in the front-rear direction according to the eccentric rotation of the tapping eccentric cam 245 a.

The massage head holder 248 has an approximately "V" or "L" shape, and two massage heads 249 are rotatably provided at both distal end portions of the massage head holder 248. The massage head 249 may have a roller shape as in this embodiment, and may have a ball (ball) shape, unlike this.

As described above, the massage head mounting member 220 is rotated in the front-rear direction with respect to the module base 210 about the rotation shaft 221 by the rotation unit, so that the position of the massage head 249 of the massage head unit can be adjusted in the front-rear direction.

Referring to fig. 4 and 11, the rotation unit includes: an air bag 250 provided between the rear surface of the module base 210 and the rear surface of the massage head mounting member 220, and inflated by air supplied from the outside to apply a force that pushes the massage head mounting member 220 forward with respect to the module base 210; an elastic member 251, such as a tension spring, applies an elastic force to the rear of the massage head mounting member 220 with respect to the module base 210, and restores the massage head mounting member 220 to an original position when the air bag 250 is contracted.

The bladder 250 may be formed of only one layer, but may be formed of a plurality of layers of two or more layers. In addition, as in this embodiment, the air bag 250 may be provided between the rear surface of the module base 210 and the rear surface of the massage head mounting member 220, as shown in fig. 12, the air bag 250 may be provided between the lower surface of the module base 210 and the lower surface of the massage head mounting member 220, or, as shown in fig. 13, may be provided both between the rear surface of the module base 210 and the rear surface of the massage head mounting member 220 and between the lower surface of the module base 210 and the lower surface of the massage head mounting member 220.

As described above, in the massage device of the present invention, the massage head mounting member 220 can be rotated in the front-rear direction with respect to the module base 210 about the rotation shaft 221 by the air bag 250 constituting the rotation unit, and thus the front-rear direction position of the massage head 249 of the massage head unit provided in the massage head mounting member 220 can be changed to perform massage. Therefore, the massage intensity and the massage form can be changed according to the body or the demand of the user according to the front-rear direction position of the massage head 249.

In addition, the air bag 250 constituting the rotation unit is formed inside the module base 210, and since the massage head unit is formed inside the massage head mounting member 220, there is an advantage in that the entire structure and size of each massage module 200 become small.

As described above, in the massager of the present invention, since two massage modules 200 are separately formed at both sides of the massager body 10 and each massage module 200 can be independently controlled while moving along the guide 100 to perform a massage function, it is possible to perform independent massage functions at different positions of the left and right portions of the user's body.

While the preferred embodiments of the present invention have been described, the present invention is susceptible to various changes, modifications and equivalents. It is obvious that the utility model can be equally applied by suitably modifying the described embodiments. Therefore, the description is not intended to limit the scope of the present invention defined by the appended claims.
