an outlet formed at a position of the rear spoiler facing the spoiler door; an air duct installed in an internal space of the rear spoiler and guiding external air introduced through the spoiler door to the outlet; a nozzle fixed to the rear spoiler and spraying a cleaning liquid to the tail gate glass; and a door opening and closing device fixed to the rear spoiler, having a first end connected to the spoiler door and a second end fluid-connected to a cleaning liquid hose, and operated to open and close the spoiler door depending on a change in a pressure of the cleaning liquid hose. ## Claims ### Claim 1 An apparatus for cleaning a tail gate glass for a vehicle, comprising: a spoiler door rotatably installed on a rear spoiler; an outlet formed at a position of the rear spoiler facing the spoiler door; an air duct installed in an internal space of the rear spoiler and guiding external air introduced through the spoiler door to the outlet; a nozzle fixed to the rear spoiler and spraying a cleaning liquid to the tail gate glass; and a door opening and closing device fixed to the rear spoiler, having a first end connected to the spoiler door and a second end fluid-connected to a cleaning liquid hose, and operated to open and close the spoiler door depending on a change in a pressure of the cleaning liquid hose. ### Claim 2 (depends on 1) The apparatus for cleaning the tail gate glass for the vehicle of claim 1, wherein the spoiler door has a rear portion coupled to an upper panel part of the rear spoiler through a hinge and a front portion rotated around the hinge, such that the spoiler door is opened and closed. ### Claim 3 (depends on 1) The apparatus for cleaning the tail gate glass for the vehicle of claim 1, wherein the outlet is formed in a lower panel part of the rear spoiler in a mesh structure and is formed to be opened toward the tail gate glass. ### Claim 4 (depends on 1) The apparatus for cleaning the tail gate glass for the vehicle of claim 1, wherein sealing pads are coupled to upper and lower ends of the air duct, respectively, in order to maintain air-tightness with the rear spoiler. ### Claim 5 (depends on 1) The apparatus for cleaning the tail gate glass for the vehicle of claim 1, wherein a nozzle hose is connected to a place at which the cleaning liquid hose and the door opening and closing device are connected to each other in a branch form, and wherein the nozzle is coupled to an end of the nozzle hose. ### Claim 6 (depends on 5) The apparatus for cleaning the tail gate glass for the vehicle of claim 5, wherein the door opening and closing device includes: a cylinder hose branched from a place at which the cleaning liquid hose and the nozzle hose are connected to each other; a cylinder connected to the cylinder hose; a piston moving along the cylinder; and a door link pivotally connecting the piston and the spoiler door to each other. ### Claim 7 (depends on 6) The apparatus for cleaning the tail gate glass for the vehicle of claim 6, wherein the nozzle hose has a diameter relatively smaller than that of the cylinder hose. ### Claim 8 (depends on 1) The apparatus for cleaning the tail gate glass for the vehicle of claim 1, further comprising: a reservoir tank connected to the cleaning liquid hose and storing the cleaning liquid therein; and a cleaning liquid motor provided on the cleaning liquid hose and operated so that the cleaning liquid in the reservoir tank is transferred to the nozzle and the door opening and closing device at a time of being operated depending on an operation of a switch.
