A railcar bogie comprising: a cross beam configured to support a carbody of a railcar; a pair of front and rear axles between which the cross beam 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; bearings respectively provided at both railcar width direction sides of the axles and configured to rotatably support the axles; front and rear axle box main bodies (8, 41) configured to respectively accommodate the bearings; plate springs extending in the railcar longitudinal direction to respectively support both railcar width direction end portions of the cross beam, each of the plate springs being supported by a pair of the front and rear axle box main bodies (8, 41), each of the plate springs being provided with first overhang portions each projecting toward a longitudinal direction from an end portion of a supporting surface of the axle box main body (8, 41); and second overhang portions respectively formed integrally with the axle box main bodies (8, 41) or respectively formed integrally with receiving seats supported by the axle box main bodies (8, 41), and respectively opposed to lower surfaces of the first overhang portions so as to be separable from the lower surfaces, wherein a bolt hole is formed at a position of one of the first overhang portion and the second overhang portion, the position being opposed to the other of the first overhang portion and the second overhang portion, characterised by a gap between the first overhang portion and the second overhang portion being formed by a bolt inserted into the bolt hole and by a sheet sandwiched between the receiving seat and the plate spring which is lower in hardness than said receiving seat and said plate spring, wherein: - either said liner is inserted in the gap, - or a sheet that is different in thickness from said sandwiched sheet replaces said sandwiched sheet. a cross beam configured to support a carbody of a railcar; a pair of front and rear axles between which the cross beam 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; bearings respectively provided at both railcar width direction sides of the axles and configured to rotatably support the axles; front and rear axle box main bodies (8, 41) configured to respectively accommodate the bearings; plate springs extending in the railcar longitudinal direction to respectively support both railcar width direction end portions of the cross beam, each of the plate springs being supported by a pair of the front and rear axle box main bodies (8, 41), each of the plate springs being provided with first overhang portions each projecting toward a longitudinal direction from an end portion of a supporting surface of the axle box main body (8, 41); and second overhang portions respectively formed integrally with the axle box main bodies (8, 41) or respectively formed integrally with receiving seats supported by the axle box main bodies (8, 41), and respectively opposed to lower surfaces of the first overhang portions so as to be separable from the lower surfaces, wherein a bolt hole is formed at a position of one of the first overhang portion and the second overhang portion, the position being opposed to the other of the first overhang portion and the second overhang portion, characterised by a gap between the first overhang portion and the second overhang portion being formed by a bolt inserted into the bolt hole and by a sheet sandwiched between the receiving seat and the plate spring which is lower in hardness than said receiving seat and said plate spring, wherein: - either said liner is inserted in the gap, - or a sheet that is different in thickness from said sandwiched sheet replaces said sandwiched sheet. - either said liner is inserted in the gap, - or a sheet that is different in thickness from said sandwiched sheet replaces said sandwiched sheet.
