A plate spring is prevented from being displaced in a longitudinal direction of the plate spring beyond the scope of the assumption. A railcar bogie (1) includes: a cross beam (4) configured to support a carbody (11) of a railcar; a pair of front and rear axles (5) between which the cross beam (4) is located and which are respectively arranged in front of and behind the cross beam in a railcar longitudinal direction so as to extend in a railcar width direction; beatings (7) respectively provided at both railcar width direction sides of the axles (5) and configured to rotatably support the axles (5); axle box main bodies (41) configured to respectively accommodate the bearings (7); plate springs (30) extending in the railcar longitudinal direction to respectively support both railcar width direction end portions (4a) of the cross beam (4), both longitudinal direction end portions (30c) of the plate springs being respectively arranged above the axle box main bodies (41) to be respectively supported by the axle box main bodies (41); and a first side wall (31b) arranged at a plate spring longitudinal direction outer side of each of the longitudinal direction end portions (30c) of the plate springs (30) and configured to restrict parallel displacement of the plate spring (30) relative to an upper surface of the axle box main body (41) in the longitudinal direction, the parallel displacement being longer than predetermined parallel displacement.
