The present invention relates to a transmission for an electric vehicle, which comprises: an input shaft and an output shaft, which are placed parallel to each other; a planetary gear apparatus provided with three rotary elements having a rotary shaft parallel to the input shaft; a first power transfer instrument placed to transfer the power of the input shaft to a first rotary element of the planetary gear apparatus; a second power transfer instrument placed to transfer the power of a second rotary element of the planetary gear apparatus to the output shaft; a binding means installed to bind the rotation of a third rotary element of the planetary gear apparatus; a deceleration transfer instrument placed to reduce the power of the first rotary element of the planetary gear apparatus so as to transfer the reduced power to the third rotary element of the planetary gear apparatus; and a first clutch placed to interrupt two of the rotary elements of the planetary gear apparatus. The present invention aims to provide the transmission for the electric vehicle, which is able to secure an excellent power transfer efficiency and a smooth transmission.

    본 발명은 서로 평행하게 배치된 입력축 및 출력축과; 상기 입력축과 평행한 회전축을 가진 3개의 회전요소를 구비한 유성기어장치와; 상기 입력축의 동력을 상기 유성기어장치의 제1회전요소로 전달할 수 있도록 구비된 제1동력전달기구와; 상기 유성기어장치의 제2회전요소의 동력을 상기 출력축으로 전달할 수 있도록 구비된 제2동력전달기구와; 상기 유성기어장치의 제3회전요소의 회전을 구속할 수 있도록 설치된 구속수단과; 상기 유성기어장치의 제1회전요소의 동력을 감속하여 상기 유성기어장치의 제3회전요소로 전달할 수 있도록 구비된 감속전달기구와; 상기 유성기어장치의 회전요소들 중 두 회전요소를 서로 단속시킬 수 있도록 구비된 제1클러치를 포함하여 구성된다.
