Abstract
A wheel support rotatably supports a dirigible wheel. An upper wheel-support support member connects an upper portion of the wheel support to the vehicle body, and a lower wheel-support support member connects a lower portion of the wheel support to the vehicle body. The upper and lower wheel-support support members are arranged to respectively define upper and lower pivot points which define an imaginary kingpin axis. At least one of the upper and lower wheel-support support members is formed of a pair of separate link members one end of each of which is pivoted on the vehicle body at different portions of the vehicle body and the other end of each of which is rotatably connected to the wheel support at different portions of the wheel support. The upper and lower wheel-support support members are arranged so that the upper portion of the wheel support is displaced more inward than the lower portion thereof when the wheel makes a turn as the outer wheel, and so that the upper portion of the wheel support is displaced less inward than than the lowr portion thereof when the wheel makes a turn as the inner wheel.
