ABSTRACT:
A toy vehicle having a chassis and a plurality of wheels mounted on the chassis includes a wind up motor which is connected to at least one of the wheels. At least one detent is located in association with the wheel which is connected to the wind up motor. A member is mounted on the vehicle which is capable of engaging with the detent whenever the wheels of the vehicle no longer contact a support surface. Contact of the member in the detent prevents unwinding of the motor. Thus, whenever the wheels of the vehicle are not supported on the contact surface such as when the vehicle is overturned or the like the motor is prevented from unwinding.
