PURPOSE: A reduction gear for a vehicle is provided to be implemented as a differential device by connecting multiple planetary gear sets. CONSTITUTION: A planetary gear set(30) is connected to an input shaft(10). A differential part(50) is connected to the planetary gear set. The differential part is connected to a first output shaft(22) and a second output shaft(24). The differential part reduces rotation speed. A friction element(70) implements a transmission of forward second speed by restricting the planetary gear set. A first sun gear(32) is connected to the input shaft. A first planetary gear(34) is connected to the first sun gear. A first ring gear(36) is connected to the first planetary gear. The first ring gear is connected to a case by the friction element. A second sun gear(37) is connected to the case by the friction element. A second planet gear(38) is connected to the second sun gear. The second planet gear is connected to the first ring gear. A second ring gear is connected to the second planetary gear. The second ring gear is connected to the first planetary gear. |
