In the present invention, even if the steering device of a steering truck that is performing the front/back support of a steering shaft only with a steering mechanism breaks, separation of a truck frame and an axle is prevented and a vehicle body continues to be supported. A railway vehicle steering truck (11) is provided with an axle box support device for a steering shaft (2) that is caused to be such that the front/back support in the direction of progress of the vehicle of the axle boxes (4) that rotatably support the steering shaft (2) is performed by means of a steering device (3) wherein a steering link (3a) that is rotatably connected to the axle boxes (4) and a connecting link (3c) that is rotatably connected to a bolster (7) are each rotatably connected to a steering lever (3b) connected rotatably to the truck frame (6). Stoppers (12) to which the axle boxes (4) of the steering shaft (2) contact when the forward/backward movement of the axle boxes (4) exceeds the range of forward/backward movement at the time of maximum steering when passing through a minimum curve are installed at both the side of an extended and the side of a contracted wheel base in the truck frame (6).
