ものである。According to the present invention, a shaft spring is provided.
A leaf spring formed of fiber reinforced resin or the like is formed, and both ends joined to the axle box are twisted by 90 ° with respect to the central portion, so that appropriate rigidity in the vertical and horizontal directions can be obtained. And by arranging it in an X-shape, it is possible to omit the bogie frame composed of the side beams and cross beams of the conventional bogie for railway vehicles, and at the same time to omit the shaft spring device. The present invention proposes a bogie for a railway vehicle characterized in that the pillow spring can be omitted depending on the traveling speed and the purpose of use.

Is performed at both ends of the leaf spring, and at the center of the leaf spring in the left-right direction. By adopting such a structure, the shaft spring device, the pillow spring device, the rigid bogie frame and the like in the conventional bogie are eliminated, and the bogie structure is simplified and lightened.
