In a bogie (1) for a railway vehicle, an air spring (6, 30) includes upper and lower opposed surfaces (11A, 13A, 31A, 33A) which are apart from each other in an up-down direction and face each other, a stopper rubber (21, 41) fixed to one opposed surface (13A, 33A) of the upper and lower opposed surfaces, and a stopper rubber receiver (22, 42) fixed to the other opposed surface (11A, 31A). A relative position between the upper and lower opposed surfaces varies from an initial state in response to a displacement of a vehicle body (7) in a front-back direction and a left-right direction allowed by the air spring. Separation distances to the one opposed surface in the up-down direction at left and right end portions (22L, 22R, 42L, 42R) of the stopper rubber receiver are shorter than that at a central portion (22M, 42M), and separation distances to the one opposed surface in the up-down direction at front and back end portions (22F, 22B, 42F, 42B) of the stopper rubber receiver are longer than that at the central portion.
