Abstract: A driving device for a toy vehicle according to the present disclosure is a driving device for a toy vehicle, and includes: a first rotating body configured to be rotatable around a first rotation axis by a motor, the first rotating body having a wall portion formed to have a surface whose distance from the first rotation axis gradually decreases along a circumferential direction about the first rotation axis; a second rotating body configured to be rotatable around a second rotation axis by being pressed by the surface of the wall portion that rotates; and a third rotating body configured to be rotatable around a third rotation axis by the second rotating body.

Abstract: A wheel device for a toy vehicle, in which one of a pair of wheels rolling on a pair of metal rails attracts with a magnet to reduce resistance caused by magnetic force and suppress load on a motor. The wheel device 1 includes a first axle 2, and a first wheel 10 and a second wheel 20 provided on opposite sides of the first axle 2. The first wheel 10 includes a first wheel main body 11 rolling on one of the rails 261 and a first flange 12 guided by the one rail. The second wheel 20 includes a second wheel main body 21 rolling on the other of the rails 261 and a second flange 22 guided by the other rail. The second wheel main body 21 is formed of a magnet.
