a rear spoiler positioned at a rear of the vehicle body, connected to the roof portion and including an opening through which air passes; a variable shutter positioned at the rear spoiler and configured to adjust an opening amount and an opening position of the opening; and an actuator configured to operate the variable shutter. ### Claim 2 (depends on 1) The rear spoiler system of claim 1, further comprising a rear glass positioned under the opening, wherein the rear glass is cleaned by air passing through the opening. ### Claim 3 (depends on 1) The rear spoiler system of claim 1, further comprising: a vehicle operation detection unit configured to measure an operation state of the vehicle and outputting a corresponding signal; and a controller configured to adjust the opening amount or the opening position of the opening by controlling the actuator based on the output signal of the vehicle operation detection unit. ### Claim 4 (depends on 3) The rear spoiler system of claim 3, wherein the actuator includes an operating motor driving the variable shutter, wherein the variable shutter is moved by rotation of the operating motor. ### Claim 5 (depends on 4) The rear spoiler system of claim 4, wherein the rear spoiler includes a guide bar positioned on each side of the variable shutter in a direction parallel to a movement direction of the variable shutter, and the guide bar being configured to guide movement of the variable shutter. ### Claim 6 (depends on 5) The rear spoiler system of claim 5, wherein the variable shutter includes: a first shutter mounted on a front portion of the rear spoiler configured to be moved in a length direction of the vehicle body; and a second shutter mounted on a rear portion of the rear spoiler configured to be moved in the length direction of the vehicle body; and wherein the operating motor includes: a first motor driving the first shutter; and a second motor driving the second shutter. ### Claim 7 (depends on 6) The rear spoiler system of claim 6, wherein the first shutter and the second shutter are each moved along the guide bar, wherein one of a protrusion and a groove in contact with the protrusion and blocking the opening is positioned at one end of the first shutter, and wherein an other one of the protrusion and the groove is positioned at one end of the second shutter. ### Claim 8 (depends on 6) The rear spoiler system of claim 6, wherein the first motor and the second motor are each driven independently from each other by the controller. ### Claim 9 (depends on 3) The rear spoiler system of claim 3, wherein the vehicle operation detection unit includes a speed sensor, and when the detected speed of the vehicle is less than a set first speed, the controller controls operations of the first motor and the second motor to allow the variable shutter to be opened by a set first opening amount. ### Claim 10 (depends on 9) The rear spoiler system of claim 9, wherein the first shutter is positioned on the front portion of rear spoiler. ### Claim 11 (depends on 9) The rear spoiler system of claim 9, wherein when the speed of the vehicle is the set first speed or more, but less than a second speed, the controller controls the operations of the first motor and the second motor to allow the variable shutter to be opened by a set second opening amount. ### Claim 12 (depends on 11) The rear spoiler system of claim 11, wherein the opening position of the variable shutter is adjacent to a central portion of the rear spoiler. ### Claim 13 (depends on 9) The rear spoiler system of claim 9, wherein when the speed of the vehicle is the set second speed or more, the controller controls the operations of the first motor and the second motor to allow the variable shutter to maintain a closed state.
