         9 . The toy vehicle as claimed in  claim 1 , wherein one ends of right and left driven links are supported by the chassis swingablly in a horizontal direction, a driving link is crossed over between other ends of the right and left driven links, two spindles are swingablly supported by the right and left driven links, each of the two spindles is connected to the front wheel axle through a flexible joint, the front wheel axle is supported by the chassis, the front wheel axle is supported by the two spindles, and the flexible joint comprises a cylindrical body provided on one of the spindle and the front wheel axle, and an engaging part provided on the other thereof to protrude radially, end parts of the two spindles and the front wheel axle fitting with each other, a slit for making the engaging part fit therein being formed in the cylindrical body, and the engaging part fitting in the slit.  
     
     
         10 . The toy vehicle as claimed in  claim 7 , wherein the driving link comprises a permanent magnet, and coils provided at positions across the permanent magnet.  
     
     
         11 . The toy vehicle as claimed in  claim 8 , wherein the driving link comprises a permanent magnet, and coils provided at positions across the permanent magnet.  
     
     
         12 . The toy vehicle as claimed in  claim 9 , wherein the driving link comprises a permanent magnet, and coils provided at positions across the permanent magnet.  
     
     
         13 . The toy vehicle as claimed in  claim 7 , wherein the driving link comprises a coil, and permanent magnets provided at positions across the coil.  
     
     
         14 . The toy vehicle as claimed in  claim 8 , wherein the driving link comprises a coil, and permanent magnets provided at positions across the coil.  
     
     
         15 . The toy vehicle as claimed in  claim 9 , wherein the driving link comprises a coil, and permanent magnets provided at positions across the coil.  
     
     
         16 . The toy vehicle as claimed in  claim 7 , wherein the driving link comprises a non-magnetized magnetic material, and coils provided at positions across the non-magnetized magnetic material.  
     
     
         17 . The toy vehicle as claimed in  claim 8 , wherein the driving link comprises a non-magnetized magnetic material, and coils provided at positions across the non-magnetized magnetic material.
