To provide a lightweight single axle bogie for rolling stock suited for a streetcar with a 100 percent low-floor, having a simple structure, capable of preventing pitching and driving with its wheels cornering smoothly along tracks even if the tracks are steeply curved lines with their minimum turning radius of 30 m or less.
A wheel 14 is rotatably attached inside the central position in the longitudinal direction of a pair of right and left axle beams 12 via an axle 13 so as to be rotatable. The respective axle beams 12 are linked pivotably by a lateral-long link 15 at the end parts so as to be rotatable. The base end of a track frame 11 is linked so as to be pivotable in the vertical direction of a vehicle body 2. The vicinity of the axle 13 of the wheel 14 of the axle beam 12 is pivotably linked under the vicinity of front ends of both side beams 11c of the track frame 11 so as to be pivotable. The front end part 16a of a base link 16 is linked on the base ends of the respective axle beams 12 via cross pins 18 so as to be rotatable in the horizontal and vertical directions. The base end 16b of the base link 16 is linked so as to be horizontally pivotable relative to the track frame 11.
