a wheelhouse assembly positioned on the chassis frame and defining a side surface of the deck; and a reinforcement structure positioned at an end of the wheelhouse assembly at a position where a rear gate is positioned at a rear end of the deck. ### Claim 2 (depends on 1) The structure of claim 1, wherein the reinforcement structure comprises a gradation part in which a plurality of rigid ribs are positioned in a height direction. ### Claim 3 (depends on 2) The structure of claim 2, wherein the reinforcement structure is fastened to a side member positioned at the rear end of the deck. ### Claim 4 (depends on 3) The structure of claim 3, wherein the plurality of rigid ribs are positioned at equal intervals along the height direction based on the side member. ### Claim 5 (depends on 4) The structure of claim 4, wherein the reinforcement structure further comprises: a rigid part provided at an end of the gradation part; a striker part positioned on the rigid part and fastened to a locker of the rear gate; and a hinge part positioned between the rear gate and the rigid part to rotatably open and close the rear gate. ### Claim 6 (depends on 5) The structure of claim 5, wherein the equal intervals between the plurality of rigid ribs are smaller than an interval of a mounting hole such that the striker part is fastened to the reinforcement structure or are smaller than a mounting hole where the hinge part is positioned. ### Claim 7 (depends on 5) The structure of claim 5, further comprising a rear hook part positioned adjacent to one rigid rib of the plurality of rigid ribs. ### Claim 8 (depends on 7) The structure of claim 7, wherein the one rigid rib and one end of the rigid part have a ‘P’-shaped cross section. ### Claim 9 (depends on 3) The structure of claim 3, wherein the plurality of rigid ribs have an equal angle along the height direction based on the side member. ### Claim 10 (depends on 1) The structure of claim 1, further comprising: chassis mounting parts positioned on the wheelhouse assembly in contact with the chassis frames; and vertical ribs extending in a height direction of the chassis mounting parts of the wheelhouse assembly, wherein the chassis mounting parts, the reinforcement structure, and the wheelhouse assembly are integrally configured. ### Claim 11 (depends on 10) The structure of claim 10, further comprising a side hook part at a position corresponding to one of the vertical ribs. ### Claim 12 A structure for reinforcing a deck of a vehicle, the structure comprising: chassis frames positioned on both side surfaces of a lower end of the deck of the vehicle; a wheelhouse assembly positioned on the chassis frame and shaped according to a curvature of wheels of the vehicle; a side member positioned at a rear end of the deck; and a reinforcement structure positioned at an end of the wheelhouse assembly at a position where a rear gate is positioned at the rear end of the deck, wherein the reinforcement structure comprises a gradation part in which a plurality of rigid ribs are positioned at equal intervals in a height direction of the side member. ### Claim 13 (depends on 12) The structure of claim 12, wherein the reinforcement structure further comprises: a rigid part provided at an end of the gradation part; a striker part positioned on the rigid part and fastened to a locker of the rear gate; and a hinge part positioned between the rear gate and the rigid part to rotatably open and close the rear gate. ### Claim 14 (depends on 13) The structure of claim 13, wherein the equal intervals of the plurality of rigid ribs are smaller than an interval of a mounting hole such that the striker part is fastened to the reinforcement structure or are smaller than an interval of a mounting hole where the hinge part is positioned. ### Claim 15 (depends on 12) The structure of claim 12, wherein the plurality of rigid ribs have an equal angle along the height direction based on the side member. ### Claim 16 (depends on 12) The structure of claim 12, further comprising a rear hook part positioned adjacent to one rigid rib of the plurality of rigid ribs. ### Claim 17 (depends on 16) The structure of claim 16, wherein: the reinforcement structure further comprises: a rigid part provided at an end of the gradation part; a striker part positioned on the rigid part and fastened to a locker of the rear gate; and a hinge part positioned between the rear gate and the rigid part to rotatably open and close the rear gate; and the one rigid rib and one end of the rigid part have a ‘P’-shaped cross section. ### Claim 18 (depends on 12) The structure of claim 12, further comprising: chassis mounting parts positioned on the wheelhouse assembly in contact with the chassis frames; and vertical ribs extending in a height direction of the chassis mounting parts of the wheelhouse assembly. ### Claim 19 (depends on 18) The structure of claim 18, further comprising a side hook part at a position corresponding to one of the vertical ribs. ### Claim 20 (depends on 12) The structure of claim 12, wherein the wheelhouse assembly and the reinforcement structure are integrally cast.
