- a body having a wall portion;
a guide hole in said wall portion;
a steerable wheel mounted on an axle;
an upright member on which said axle is fixedly mounted;
an upright holder disposed below said guide and rotatably supporting said upright member to permit rotation of said upright member during a steering operation;
an upwardly extending rod having a lower portion fixedly mounted to said upright holder;
said rod having an upper portion movably guided in said guide hole;
a spring acting upon said upright holder to bias said upright holder downwardly away form said guide; and
a single swing arm having two ends, one end being pivotally connected to said body, and the other end being pivotally connected to said upright holder;

Abstract
Suspension systems (10; 42; 8) operate independently of each other on opposite sides of a vehicle toy. The systems have their road wheels move up and down substantially without any inclination of these wheels, and are simple in construction. Each suspension system has an upright member (16) on which the wheel axle (13) is fixedly mounted, an upright holder (18) for holding the upright member (16) so as to permit it to be rotatable in a steering operation, a rod (22) having its lower portion fixedly mounted to the holder (18) and its upper portion guided in a guide (24) formed in an upper portion of the body, and a compression spring (26) interposed between the holder (18) and the guide (24). A swing arm (20) has one end pivotally connected to the body and the other end pivotally connected to the holder (18). The upright member (16) and the upright holder (18) may be integrally formed as a support (82) rotatably mounted on the lower portion of the rod.
