Abstract
A steerable trailer to be drawn by a vehicle is disclosed having a pair of first and a pair of second steerable wheels. Each of the steerable wheels are retained by a wheel support which is rotatable relative to the trailer frame about a steering axis. A tongue is pivotably attached to the frame for connecting the trailer to the towing vehicle. A flexible tensile member is attached to the tongue and extends about an engagement surface affixed to the wheel supports. The first and second wheel supports rotate in opposite directions in response to the pivoting of the tongue relative to the frame to steer the trailer.
