Abstract
A bogie for a low floor type railway vehicle, in which the accuracy of the distance between left and right wheels is enhanced and which enables a vehicle body to be low-floored. The bogie has a bogie frame for supporting the body of the railway vehicle, a main axle and an auxiliary axle arranged so as to laterally extend at the front and rear in the traveling direction of the bogie frame, wheels attached to both the left and right sides of each of the axles, shaft boxes attached to both the left and right sides of each of the axles and supporting the axle, and shaft box support devices respectively supporting each of the shaft boxes by elastically joining the shaft boxes and the bogie frame together. The wheels attached to the main axle are large-diameter wheels, and the wheels attached to the auxiliary axle are small-diameter wheels having a smaller diameter than the large-diameter wheels.
