ABSTRACT:
The lower end of each of the front legs (1) of a baby carriage is fabricated of a hollow pipe and vertically directed. A rotary yoke (13) supporting a wheel (15) is held by and attached to the front leg (1) to surround the lower end of the front leg (1) so that it is rotatable around the axis of the lower end of the front leg (1). The rotary yoke (13) is also vertically movable and, when subjected to the action of a cushion spring (6) received in the lower end of the front leg (1), allows the cushioning action to be exerted. Further, there is provided an operating lever (22) for selectively inhibiting the rotary yoke (13) from rotating to change the direction of the wheel (15).
