A seesaw type brake pad for a railway vehicle having a dual curved surface structure comprises: a frictional material being in contact with a brake disk; a frictional material supporting plate having the frictional material fixed thereto; and a back plate combined with the frictional material supporting plate. The frictional material supporting plate includes: a first right-side acting surface and a first left-side acting surface forming a predetermined area at a center, protruding or recessed and extending in a pair; and a pair of rotation-preventing balls protruding from both ends of the frictional material supporting plate. The back plate includes: a second right-side acting surface forming a predetermined area and combined with the first right-side acting surface; a second left-side acting surface forming a predetermined area and combined with the first left-side acting surface; and a pair of rotation-preventing grooves having the rotation-preventing balls inserted thereinto and guiding the movement of the rotation-preventing balls. The seesaw type brake pad having a curved surface can improve structural durability and braking performance.
