The present invention relates to a planetary gear apparatus, and more specifically, relates to a planetary gear apparatus installed in a gear ratio converter of an active front steering device to compensate for the gap between gear teeth of a sun gear and planetary gear, thereby reducing rattle noise. According to the present invention, a planetary gear apparatus circumscribing a sun gear unit including input and output sun gears in the gear ratio converter of the active front steering device comprises: a planetary gear unit including an input planetary gear circumscribing the input sun gear and an output planetary gear circumscribing the output sun gear; a planetary gear shaft wherein the input planetary gear is installed on one side and the output planetary gear is installed on the other side; and an elastic member disposed between the input and output planetary gears to compensate for the gap between the gear teeth of the sun gear unit and the planetary gear unit.

    본 발명은 유성기어장치에 관한 것으로써, 구체적으로는 능동전륜장치(Active Front Steering)의 기어비변환장치에 설치되어 선기어와 유성기어의 기어치간 유격을 보상하여 래틀(rattle) 소음을 저감할 수 있는 유성기어장치에 관한 것이다. 본 발명은 능동전륜장치(Active Front Steering)의 기어비변환장치에서 입력선기어와 출력선기어로 구성된 선기어부에 외접하는 유성기어장치에 있어서, 상기 입력선기어와 외접하는 입력유성기어, 상기 출력선기어와 외접하는 출력유성기어로 구성된 유성기어부와, 일측에 상기 입력유성기어가 설치되고, 타측에 상기 출력유성기어가 설치된 유성기어축과, 상기 입력유성기어와 상기 출력유성기어 사이에 배치되어 상기 선기어부와 상기 유성기어부의 기어치간 유격을 보상하는 탄성부재를 포함한다.
