Claims

[Claims for Utility Model Registration] An input shaft, a first output shaft that transmits driving force to the first wheel of the front wheels and rear wheels that is always in a driving state, and a planetary gear type reduction mechanism disposed between the first output shaft and the second wheel and connected to the input shaft; and a driving force transmission mechanism that transmits driving force to a second wheel that is selectively brought into a driving state. a sleeve member that rotates together with the first output shaft and is movable in the axial direction of the first output shaft; and an output member of the speed reduction mechanism;
The input shaft and the input member of the driving force transmission mechanism each have an engaging portion that can be engaged with the sleeve member, and the sleeve member has at least an engaging portion that is formed on the input shaft. a first position in the axial direction that can be engaged with the input shaft, and a second position in the axial direction that can be simultaneously engaged with the respective engaging portions formed on the input shaft and the input member of the driving force transmission mechanism. and a third position in the axial direction at which the third position can be simultaneously engaged with respective engaging portions formed on the output member of the speed reduction mechanism and the input member of the driving force transmission mechanism. 4 characterized by
