[OBJECT] To protect an elastic member and to perform a uniform surface pressure function. [MEANS] A brake lining for a railroad car being pressed by a brake caliper against a sliding surface of a brake disc body mounted on to an axleor a brake disc bolted to a wheel, which is pressed by a brake caliper. There are provided friction members 11 which are pressed onto the sliding surface of a brake disc, and a back plate 12 which is attached to the brake caliper in order to support the friction members 11. The friction members 11 are dividedly arranged in a radial direction and in a circumferential direction of the brake disc. A disc spring 13 is disposed between each respective friction member 11 and the back plate 12. An outer peripheral surface of the friction members facing the back plate is formed in a convex curved shape in an area outside the elastic member. When a light pressing force is applied, a pressing force is transmitted from the back plate 12 to the friction members 11 via the disc springs 13. When a heavy pressing force is applied, the back plate 12 and a rounded surface portion 11a make contact, thereby directly transmitting a pressing force to the friction members 11. [ADVANTAGEOUS EFFECT] It becomes possible to achieve a uniform surface pressure and to prevent deformation and deterioration of the elastic members.
