Electric powered driving device

An electric travel device, according to the present invention, comprises: a housing, in which an electricity-driving motor for generating power is accommodated, and which is formed such that a user can ride the same; a traveling wheel disposed in the housing so as to carry out rotational motion by the driving force provided by the electricity-driving motor; one pair of pedals disposed across the traveling wheel therebetween and supporting the both feet of the user riding the electric travel device during the riding of the user; and an auxiliary traveling unit disposed corresponding to the one pair of pedals and coming into contact with the road surface during the traveling of the traveling wheel so as to carry out rotational motion. Therefore, when the user travels, the auxiliary traveling unit disposed at both sides of the traveling wheel can prevent falling in the lateral direction of the traveling direction, thereby improving the traveling stability.
