A brake device for a railway vehicle includes: a regular electric motor having a rotatable regular-side rotor; a transmission shaft member extending from the regular electric motor in the direction of the rotation axis of the regular-side rotor and rotated by the rotational force output from the regular-side rotor; a conversion mechanism attached to the transmission shaft member and configured to convert the rotational motion of the transmission shaft member into linear motion; friction members configured to receive the linear motion to be pressed against a brake-applied member of the railway vehicle, so as to brake the railway vehicle; and a security power unit attached to the transmission shaft member and configured to output the rotational force to the transmission shaft member.

This brake lining includes: a plurality of friction members which are arranged to be spaced from each other, each of the friction members having a front surface that is to face a sliding surface of a brake disk; a back board fastened to a back surface of each of the friction members; a base plate that supports each of the friction members at a region including a center portion of each friction member; and an elastic member disposed between the base plate and the back board, on a back surface side of each friction member. Two friction members that are adjacent to each other are taken as a pair, and the back board is fastened to each of the pairs of friction members. In each pair of friction members, the two friction members are arranged along the circumferential direction of the brake disk.
