ABSTRACT:
A toy vehicle is disclosed including a gear changing mechanism for use in conjunction with a flywheel driving device. The mechanism comprises a gear changing lever pivotally mounted to a frame by means of a pin. The lever is biased in one direction by means of a first spring member to hold the axle of an idle gear in engagement with one end of an elongated opening formed in the frame. The gear changing lever is adapted to pivot by a depressing action against the force of the first spring member to disengage the idle gear axle from the one end of the elongated opening so as to allow a second spring member to urge the idle gear axle against the other end of the elongated opening.
