PROBLEM TO BE SOLVED: To reduce man-hours required to adjust right and left wheel load balance in a four-point supported articulated truck. SOLUTION: A first joint part 10 located at the center part of the articulated truck and at the center part of a coupler body provides an angle of intersection to front and rear vehicle bodies, with the center part of the articulated truck as a reference when rolling stock passes a curved track, and a second joint part 29 permits relative displacement between a body upper part 26 of the coupler body and a vehicle 5 to which a coupler seat 27 is fixed. A combination of the first joint part 10 and second joint part 29 can provide omnidirectional freedom to the positional relationship of the vehicle end parts of the front and rear vehicle bodies connected by a coupler 7. When the vehicle height of the vehicle body 5 is adjusted, the transmission of the displacement of the vehicle body 5 to the other vehicle body through the coupler 7 is prevented to reduce man-hours required to adjust the right and left wheel load balance of both the front and rear vehicle bodies.
