The massage module may include: a procedure member including an upper finger member and a lower finger member cooperating with the upper finger member; and a cam driving part connected to the upper finger member so as to move the upper finger member in the vertical direction, so that the upper finger member and the lower finger member are away from or close to each other. ## Claims ### Claim 1 A massage module comprising: a treatment member including a first finger member, a second finger member disposed adjacent to the first finger member and configured to cooperate with the first finger member, and a cam link non-rotatably coupled to the first finger member; and a cam driving portion connected to the first finger member by the cam link and configured to move the first finger member and the second finger member to be away from or close to each other in a first direction or in a second direction opposite to the first direction. ### Claim 2 (depends on 1) The massage module of claim 1, wherein the cam driving portion is configured to move the first finger member in the first direction and the second direction through eccentric rotation, and wherein the second finger member is configured to move away from or close to the first finger member while cooperating with movement of the first finger member. ### Claim 3 (depends on 1) The massage module of claim 1, wherein the treatment member comprises two finger gears disposed on the first finger member and the second finger member, respectively, and the two finger gears configured to be engaged with each other and to rotate in mutually opposite directions. ### Claim 4 (depends on 1) The massage module of claim 1, wherein the cam driving portion comprises: a cam driving motor configured to generate a rotational force; a kneading shaft connected to a driving shaft of the cam driving motor and configured to rotate corresponding to drive of the cam driving motor; and a cam unit connected to the kneading shaft and configured to eccentrically rotate on the kneading shaft corresponding to rotation of the kneading shaft. ### Claim 5 (depends on 4) The massage module of claim 4, wherein the cam unit comprises: an unbalanced cover connected to the kneading shaft; and a cam cover in which the unbalanced cover is fit and to which the unbalanced cover is coupled. ### Claim 6 (depends on 5) The massage module of claim 5, wherein the cam unit further comprises a cam bearing inserted between the unbalanced cover and the cam cover. ### Claim 7 (depends on 1) The massage module of claim 1, wherein the treatment member comprises: a first finger gear configured to rotate corresponding to movement of the first finger member wherein a stopper gear groove is defined on the first finger gear and configured to hold and regulate rotational movement of the first finger gear to restrict movement displacement of the first finger member; and a second finger gear disposed to come into contact with the first finger gear and configured to transmit a rotational force in a direction opposite to a rotation direction of the first finger gear to the second finger member. ### Claim 8 (depends on 1) The massage module of claim 1, wherein the treatment member comprises the cam link which has a first portion connected to the cam driving portion by a pin connection structure having a centric through-hole and a second portion non-rotatably installed on the first finger member, wherein the pin connection structure is configured to move the first finger member and the second finger member to be away from or close to each other in the first and the second direction. ### Claim 9 (depends on 8) The massage module of claim 8, wherein the pin connection structure comprises: a cam cover protruding portion disposed on the cam driving portion, wherein the centric through-hole is defined in the cam cover protruding portion, and wherein a cam unit is configured to be adjusted in angle with the cam link when the cam link eccentrically rotates. ### Claim 10 (depends on 9) The massage module of claim 9, wherein the pin connection structure comprises: the cam link having a first cam link and a second cam link; a cam shaft insertion hole defined in each of the first cam link and the second cam link; and a cam shaft inserted into the centric through-hole and the cam shaft insertion hole of the first cam link and the cam shaft insertion hole of the second cam link, wherein the cam cover protruding portion is disposed between the first cam link and the second cam link, and wherein a size and a shape of the centric through-hole corresponds to a size and a shape of the cam shaft insertion hole. ### Claim 11 (depends on 1) The massage module of claim 1, wherein the treatment member comprises a first treatment member and a second treatment member disposed on a first side and a second side of a main bracket, respectively, wherein the second side is disposed adjacent to the first side, and the first treatment member and the second treatment member are installed to be tilted at a predetermined angle toward a center. ### Claim 12 (depends on 1) The massage module of claim 1, wherein the treatment member comprises: a first finger housing link-connected to the cam driving portion; a first finger bracket installed or disposed on the first finger housing to have a predetermined angle therebelow; and a first massage roller rotatably installed on the first finger bracket and configured to perform a massage. ### Claim 13 (depends on 1) The massage module of claim 1, wherein the treatment member comprises: a second finger housing; a second finger bracket installed or disposed on the second finger housing to have a predetermined angle thereabove; and a second massage roller rotatably installed on the second finger bracket and configured to perform a massage. ### Claim 14 (depends on 1) The massage module of claim 1, further comprising a lateral driving portion configured to laterally move the treatment member. ### Claim 15 (depends on 1) The massage module of claim 1, wherein the treatment member comprises a first treatment member and a second treatment member, and wherein the massage module further comprises a lateral driving portion configured to laterally move the first treatment member and the second treatment member to be away from or close to each other. ### Claim 16 (depends on 15) The massage module of claim 15, wherein the lateral driving portion further comprises: a lateral driving motor configured to generate a rotational force; a first rotational shaft and a second rotational shaft, each configured to rotate corresponding to the rotational force of the lateral driving motor, wherein the first rotational shaft has a first screw in a first screw direction and the second rotational shaft has a second screw in a second screw direction opposite to the first screw direction; and a first rotational shaft housing and a second rotational shaft housing disposed on the first treatment member and the second treatment member, respectively, wherein the first rotational shaft housing and the second rotational shaft housing are disposed corresponding to the first screw direction and the second screw direction and a shape of the first rotational shaft and a shape of the second rotational shaft. ### Claim 17 (depends on 1) The massage module of claim 1, further comprising a front-rear driving portion configured to move the treatment member in a front-rear direction. ### Claim 18 (depends on 1) The massage module of claim 1, further comprising a vertical driving portion configured to vertically move the treatment member.
