Abstract (en)
A centering device is proposed. More particularly, according to the centering device, although a coupler coupling railroad cars, which are arranged in a front-to-rear direction, to each other is rotated leftward and rightward, the coupler is rapidly restored to initial position thereof, and in the case of the application of external force of a predetermined strength or less to the coupler, the coupler is not rotated, so when coupling the front-to-rear cars to each other, the rotation of the coupler is prevented such that the front-to-rear railroad cars are stably coupled to each other.
