Abstract
A travelling toy vehicle is provided having an external body in the shape of a dump truck or other vehicle. An internal gear box, or frame, drives two wheels on an axle. The frame contains a vibrating mechanism and rocks left and right by the motion of a spur gear disposed between two cylindrical force receiving pieces attached to the external body of the travelling toy vehicle. A power transmission route change mechanism couples driver power from a motor to the vibrating mechanism for a predetermined period of time to simulate ideling of the vehicle. Thereafter, the drive power is coupled to the travelling mechanism to provide forward movement of the travelling toy vehicle. Electrical power to the motor is switched on and off by pressing down against the rear portion of the travelling toy vehicle. An operation restricting lever mounted at the rear of the vehicle prevents the switching on of electrical power when the toy is being stored and allows manual use of the toy without propulsion by the motor.
