Abstract
An improved drive mechanism for a toy vehicle in which a pair of traction wheels are driven by a helical spring disposed coaxially about the wheel axle. The spring is connected at one end to the axle on which the traction wheels are mounted and at the other end to a housing for the axle and the spring which is rotatably mounted with respect to the vehicle body. The spring propels the vehicle after initial forward movement by the user substantially back to the point of release in an orientation opposite to that during initial forward movement of the vehicle.
