To provide a traveling toy facilitating a vehicle connection and an electric connection and having a simple vehicle connection structure and electric connection structure.

This traveling toy has parts where vehicles equipped with a circuit components are mutually connected, each vehicle has a connection arm for connecting the vehicle to each other, the tip of each connection arm is disposed with two magnetic bodies electrically insulated from each other, the two magnetic bodies in one vehicle and the two magnetic bodies in the other vehicle are constituted to be attracted one-to-one on mutual conductive magnetic-attraction faces, The conductive magnetic-attraction face is electrically connected to a circuit component equipped on the vehicle having the conductive magnetic-attraction face and, when the two magnetic bodies in one vehicle and the two magnetic bodies in the other vehicle are mutually magnetically attracted by their mutual conductive magnetic-attraction faces, the circuit components between the both vehicles are simultaneously electrically connected via the magnetic attraction parts.
