ABSTRACT:
A radio-controlled toy car which can smoothly turn its running direction even when the toy car is running with the front wheels kept lifted from the ground, that is, even during the wheelie motion. The toy car according to the present invention comprises a differential gear mechanism, two drive shafts rotatably connected to the differential gear mechanism, two electromagnets for applying a brake force to each of the two drive shafts, independently, when energized in cooperation with one of two magnetic cylindrical members fixed to the two drive shafts separately, a front wheel and, in particular, an auxiliary rear wheel, in addition to two ordinary rear wheels and two front dummy wheels. Furthermore, since a connecting rod is provided for loosely connecting the two drive shafts, the differential gear mechanism functions reliably.
