The present invention relates to a fixed and rotating cart caster that is installed on each of the edges of a bottom surface of a manned and unmanned cart to carry a product through a rolling motion, and more particularly, to a fixed and rotating cart caster that is automatically converted into a fixed or rotating caster according to a forward/backward traveling direction of a cart to ensure safe travel and thereby easily carry a product and improve work conditions. According to the present invention, since the fixed and rotating cart caster is automatically converted into a fixed or rotating caster by an operation of a fixing and rotating unit including an auxiliary wheel that is closely attached to a wheel according to the forward/backward movement of the cart so as to rotate in only one direction and by a fixing pin inserted into a coupling hole of a fixing plate, safe travel may be ensured in order to easily carry a product and improve work conditions.
