Abstract

PURPOSE:To enable a traveling toy to vary movements thereof by steps comprising: being switched on by being pushed down after a battery power is turned on; starting traveling in a low speed; increasing a speed of traveling after electric pressure is heightened because of traveling for a certain time; as traveling in a high speed, rotating a part of the toy body so as to change a shape thereof; reverting to the former shape after traveling in a high speed for a certain time. CONSTITUTION:As a body 2 is pushed down to the shown direction of an arrow, a rear wheel axle is relatively moved upward, so that a swing lever 24 is swung upward. By swinging of the swing lever 24, the first cam 40 pushes a push switch 25 to switch on the toy, so that the toy starts traveling. After the toy is started traveling, the toy body 2 and the swing lever 24 go downward. Along with traveling of the toy, a clutch gear 23 rotates and the first cam 40 pushes the push switch 25 to be switched off. The second cam 41 pushes a free switch 26 to be switched on. After the toy travels with the free switch on for a certain time, the free switch 26 is turned off. A traveling speed is varied by lowering an electric pressure when the push switch 25 is on and by heightening an electric pressure when the free switch 26 is on.
