ABSTRACT:
In a truck for a railway vehicle having a plurality of wheels-and-axles, an arrangement is provided for permitting each wheel-and-axle an optimal steering operation when the truck runs on a curved track, and to simplify the construction of journal box locator. Each journal box is located and fitted to a truck frame by the journal box locator for locating and fitting the journal box to the truck frame in such a fashion that the orbit of movement of the journal box expands upward with respect to the center axis of the truck, and permits the relative displacement between the journal box and the truck frame by elastic deformation of elastic members.
