Abstract
To prevent separation of a truck frame and a wheel axle and to continue supporting a vehicle, even if damage has occurred to a steering device of a steering truck in which front-back support of a steering axle is performed only by a steering mechanism. A railway vehicle steering truck provided with an axle box suspension of a steering axle, which is designed to perform support in the front-back direction of an axle box which rotatably supports the steering axle, by means of a steering device having a steering link which is rotatably connected to the axle box, and a connecting link rotatably connected to a bolster, each of these being rotatably connected to a steering lever which is rotatably connected to the a truck frame. A stopper to which the axle box comes in contact is installed both on a side where a wheelbase expands and on a side where the wheelbase contracts in the truck frame, when a front-back movement of the axle box exceeds a range of front-back movement at a time of maximum steering when the front-back movement of the axle box passes through a minimum curve.
