Disclosed is a planetary gear train of an automatic transmission for a vehicle. According to an embodiment of the present invention, the planetary gear train includes: an input shaft receiving power of an engine; an output shaft outputting gear-shifted power; a first planetary gear set including first, second, and third rotary components; a second planetary gear set including fourth, fifth, and sixth rotary components; a third planetary gear set including seventh, eighth, and ninth rotary components; a fourth planetary gear set including tenth, eleventh, and twelfth rotary components; and six control components placed in a part selectively connecting the rotary components with each other, or placed in a part selectively connecting the rotary components with a transmission housing. The input shaft is directly connected with the second rotary component, the output shaft is directly connected with the eleventh rotary component, the first rotary component is directly connected with the seventh rotary component, the sixth rotary component is directly connected with the transmission housing, the fourth rotary component is directly connected with the ninth rotary component, the eighth rotary component is directly connected with the tenth rotary component, and three of the six control components are operated, and thus at least ten forward speeds and at least one reverse speed are realized. 차량용 변속기의 유성기어트레인이 개시된다. 본 발명의 일 실시 예에 따른 차량용 자동 변속기의 유성기어트레인은 엔진의 동력을 전달받는 입력축; 변속된 동력을 출력하는 출력축; 제1, 제2, 제3 회전요소를 보유하는 제1 유성기어세트; 제4, 제5, 제6 회전요소를 보유하는 제2 유성기어세트; 제7, 제8, 제9 회전요소를 보유하는 제3 유성기어세트; 제10, 제11, 제12 회전요소를 보유하는 제4 유성기어세트; 및 상기 회전요소와 회전요소를 선택적으로 연결하는 부분에 배치되거나, 상기 회전요소와 변속기 하우징을 선택적으로 연결하는 부분에 배치되는 6개의 제어요소를 포함하되, 상기 입력축은 제2 회전요소와 직접 연결되고, 상기 출력축은 제11 회전요소와 직접 연결되며, 상기 제1 회전요소는 제7 회전요소와 직접 연결되며, 상기 제6 회전요소는 변속기 하우징과 직접 연결되며, 상기 제4 회전요소는 제9 회전요소와 직접 연결되며, 상기 제8 회전요소는 제10 회전요소와 직접 연결되며, 상기 6개의 제어요소 중 3개의 제어요소가 작동되면서 적어도 전진 10속의 변속단 및 적어도 하나의 후진 변속단을 구현한다.
