a support member having an adhesive tape attached to a bottom surface and a plurality of protruding rails, which extend in one direction while spaced apart from one another at predetermined intervals, protruding upward from an upper surface;

a buttocks rest member fixed to the upper surface of the support member and including a first main body portion having the baby's buttocks placed thereon and a first toothed portion protruding downward from the first main body portion and having an outer surface having a toothed shape; and

a backrest member including a second main body portion having the baby's back placed thereon and a pair of binding portions protruding from both sides of a lower surface of the second main body portion and extending to be bent inward,

wherein, as the first main body portion is placed in a space formed by the second main body portion and the pair of binding portions, the first main body portion is disposed under the second main body portion and bound to the second main body portion while fixed to the upper surface of the support member.

2 . The functional supporter of claim 1 , wherein:

a second toothed portion having a toothed shape is provided at a side surface of an edge of each of the pair of binding portions;

the second toothed portion is connected to a pulling portion installed at the lower surface of the second main body portion and protrudes outward or retracts inward from the side surface of the edge of each of the pair of binding portions due to an operation of the pulling portion;

binding between the first main body portion and the second main body portion is strengthened by the first toothed portion and the second toothed portion being engaged with and bound to each other; and

a cross-sectional area of the second main body portion is greater than a cross-sectional area of the first main body portion in a plan view.

3 . The functional supporter of claim 2 , further comprising a cover member having a plate shape in a plan view and a through-hole formed at one side,

wherein the support member has a protruding portion formed to protrude upward from one side of the upper surface, and the cover member is coupled to the support member by the protruding portion of the support member being inserted into the through-hole.

4 . The functional supporter of claim 3 , wherein:

the first toothed portion has a round shape, and an outer surface of the corresponding round shape has a toothed shape;

an anti-slip plate made of a silicone material is attached to upper surfaces of the first main body portion and the second main body portion; and

an anti-falling step configured to prevent the baby seated on the backrest member from falling protrudes from both side portions of the second main body portion.

5 . The functional supporter of claim 4 , wherein, in a state in which the first main body portion and the second main body portion are bound to each other, when the pulling portion of the second main body portion is pulled, the second toothed portion retracts inward from the side surface of the edge of each of the pair of binding portions, and the second main body portion becomes rotatable and movable back and forth, and when the pulling portion of the second main body portion is not pulled, the second toothed portion is engaged with the first toothed portion in a state in which rotation of the second main body portion is complete, and the second main body portion is bound to the first main body portion.

6 . The functional supporter of claim 5 , further comprising an anti-falling member having a C-shape and connected to both side surfaces of the second main body portion to prevent the baby seated on the backrest member from falling,

wherein a tube configured to inject air is mounted on an upper end of the anti-falling member.

7 . A functional supporter for a baby that is installed at one side portion of a sink or a washbasin and used in placing and washing a baby, the functional supporter comprising:

a support member having an adhesive tape attached to a bottom surface and a pair of protruding rails, which extend in one direction while spaced apart from each other at a predetermined interval, protruding upward from an upper surface;

a height adjustment member disposed between the pair of protruding rails and fixed to the upper surface of the support member;

a pair of angle adjustment members each fixed to one of both side surfaces of the height adjustment member and having a cross-sectional shape in which a first portion having a rectangular cross-section and a second portion extending upward from the corresponding first portion and having a semicircular cross-section are coupled;

a buttocks rest member including a fastening portion angle-adjustably fastened to the pair of angle adjustment members, a first main body portion having the baby's buttocks placed thereon, and a first toothed portion interposed between the first main body portion and a binding portion and having an outer surface having a toothed shape; and

a backrest member including a second main body portion having the baby's back placed thereon and a pair of binding portions protruding from both sides of a lower surface of the second main body portion and extending to be bent inward,

wherein, as the first main body portion is placed in a space formed by the second main body portion and the pair of binding portions, the first main body portion is disposed under the second main body portion and bound to the second main body portion while fixed to the upper surface of the support member, and

a plurality of holes are formed around a curved circumference of the second portion of the angle adjustment member, in a state in which any one of the holes formed in the angle adjustment member overlaps any one of holes formed in the fastening portion, the buttocks rest member is fastened to the angle adjustment member through a penetrating member configured to simultaneously pass through the corresponding holes, and an angle between the buttocks rest member and the angle adjustment member is adjusted as the holes through which the penetrating member passes are changed.

8 . The functional supporter of claim 7 , wherein:

both side surfaces of the height adjustment member each include a recessed rail extending upward and recessed inward; and

both side corners of the first portion of the angle adjustment member are each coupled to one of the recessed rails and coupled to be vertically slidable.
