PROBLEM TO BE SOLVED: To constitute a truck in a compact manner while improving space efficiency of the truck and maintaining the truck balance and strength in a vehicle longitudinal direction.SOLUTION: A truck 1 for a railroad vehicle includes a cross beam 5 that extends in a vehicle width direction, and a leaf spring 30 that extends in a vehicle longitudinal direction while supporting both ends in the vehicle width direction of the cross beam 5, and is provided with a truck frame 4 rotatable in a yawing direction with respect to a bolster 3 and stoppers 41A, 41B, 45A, and 45B provided to the truck frame 4, which contact interference members 51A, 51B, 55A, and 55B connected to the bolster 3 when the truck frame 4 rotates in the yawing direction with respect to the bolder 3, and regulate the rotation range. In a state that the truck frame 4 is in a neutral position in the yawing direction with respect to the bolster 3, the stoppers 41A, 41B, 45A, and 45B are arranged on the side in the vehicle width direction of the cross beam 5 so as to overlap with the cross beam 5 in the side view. |
