A built-up toy car includes a body, and a front-wheel assembly and a rear-wheel assembly connected to lower front and lower rear ends, respectively, of the body. Both the front and the rear wheel assemblies include a flat axle part supported in two open-bottomed axle holes provided at the lower front and the lower rear ends, respectively, of the body, and two flat wheel parts connected to two ends of the axle part. Each of the axle parts is provided at upper and lower edges at positions engaging with the axle holes with two pairs of upper and lower notches to form thereat a reduced width slightly smaller than the axle holes, so that the axle parts of the front and the rear wheel assemblies are rotatable in the axle holes relative to the body of the toy car.
