PURPOSE: To provide a running toy wherein a storage battery device carried on a runner can be properly charged and exchange caused by deterioration of properties of the storage battery device is not needed to attempt to reduce cost.

CONSTITUTION: The title toy is constituted of a runner 1 carrying an electric double-layer capacitor 3, a device 11 for charging electricity rapidly charging the electrically double-layered capaditor 3 only while the runner 1 is running on a determined region, an electric voltage detecting circuit 4 detecting the charging voltage of the electric double-layer capacitor 3 and a relay 6 stopping forcibly charging the electric double-layer capacitor 3 when a charging voltage with at least a specified value is detected by means of the electric voltage detecting circuit 4.
