PROBLEM TO BE SOLVED: To provide a simply-structured lightweight single axle bogie for coupling part in a rolling stock suitable for a low-floor streetcar, applicable for a coupling bogie between cars, and capable of preventing pitching by a single axle and producing a comfortable ride feeling. SOLUTION: An axle beam 12 is journalled to the base end side lower end part of a bogie frame 11 while allowing the tip side of the axle beam to turn freely in the vertical direction, and the axle beam 12 is formed into an annular body having a square shape substantially in a plane view and supported freely rotationally via a bearing 12c through an axel 13 inward from the outside of each side on both sides of the axle beam 12. In the inside end of each axle 13, a wheel 14 is mounted integrally rotationally to be held in cantilever form. One car body 3 is provided with a coupling recess part 35 and supported on the bogie frame 11, while the other car body 3 is provided with a coupling recess part 34, and the coupling recess parts 34 and 35 are put together to be connected to each other relatively rotationally inside a central opening part 12b in the axle beam 12.
