        Abstract
A toy car includes a car body, a transmission box and a generator device, the generator device has an inductive coil sleeved on a transmission shaft extending outward from the transmission box, and a magnet sleeved on the transmission shaft with respect to the inductive coil. When the transmission shaft rotates, the magnet and the inductive coil are in an opposition movement, which generates electric power to supply load, such as bulbs to produce a lighting effect.

        BACKGROUND OF THE INVENTION
      
    
    
      
        1. Field of the Invention
      
    
    
      
        This invention relates to a toy car, and more particular to a toy car with a self-generating device to reach a lighting effect of the car.
      
    
    
      
        2. Description of the Prior Art
      
    
    
      
        As shown in 
        
          FIG. 4

         on the market comprises a handle 
        
          
            10
          
        
        . By rotating the handle 
        
          
            10
          
        
        , a spindle

         is linked to rotate and press a spring plate 
        
          
            12
          
        
        . When the handle 
        
          
            10
          
        
         is released, the restoring force of the spring plate 
        
          
            12
          
        
         drives the spindle
