Abstract
Tandem wheels mounted on a common axle are connected to a movable vehicle such as a baby carriage, stroller, wheelchair or the like in a configuration which permits maximum stability and freedom of motion. The axis of the wheels is pivotally attached and offset in trailing relation to and on opposite sides of the mounting spindle with an intermediary shock cushioning arrangement. The spindle has a common shaft with a lower section arranged to provide an interfacing shoulder to a rotatably mounted upper section. The upper section includes means for attachment to the vehicle frame.
