The present invention relates to a deceleration device for a vehicle. Specifically, the deceleration device for a vehicle comprises: a first shaft (110) coupled to a motor (111) and receiving power; a second shaft (120) connected to the first shaft (110) and primarily reducing the power; a third shaft (130) connected to the second shaft (120) and secondarily reducing the power; and a disconnector (150) which is connected to the third shaft (130) and provided between a drive shaft and a differential gear (141) of a differential (140) so as to cut off or connect the power. By adding an actuator in order to allow power of rear wheels and the motor (111) to be cut-off or connected during a front-wheel, the deceleration device can improve drive transmission efficiency and reduce energy loss. |
