Abstract

PURPOSE:To facilitate step traveling without making the diameter of a wheel larger by providing a stopper member in the supporting shaft of a chassis, while rotatably supporting a camber member in freely contact with the stopper member on a fork rotatably supported by a supporting shaft so as to make the camber member slide up a step. CONSTITUTION:When a caster travels on a flat road surface 4, the bottom surface 3b of a camber member 3 pivotably supported together with a wheel 2c by the supporting shaft 2b of a fork 2 goes down to a lower limit position 3b by its dead weight and as well the top end 3c is drifted away from the groove 1c of a stopper member 1b provided in a chassis 1. As a result, the fork 2 can oscillate around the supporting shaft 1a of the chassis 1. On the other hand, when the caster approaches the step 4a, the camber member 3 rides on the step 4a so that the bottom surface 3b goes up from the lower limit position 3b' and the top end 3c is also brought into contact with the groove 1c. As a result, the bottom surface 3b of the camber member 3 slides up the step 4a while the wheel 2c advances floating.
