Abstract: A low-slung electric vehicle that facilitates the operation of mounting and removing a battery unit while also preventing the rattling of the mounted battery unit. In addition, the battery unit is capable of preventing an operator from forgetting to disconnect a cable when removing the battery unit. A battery unit is provided with rolling rollers. Recesses are formed in upper sides of guide rails to accommodate the rolling rollers to permit the rolling rollers to drop therein when the battery unit is moved to a terminal position. Engaging projections and engagement holes are formed on a lower side of the battery unit and an upper side of a floor plate such that the engaging projections and the engagement holes are fitted to each other when the rolling rollers drop into the recesses. After an access gate is closed, a connecting cable is looped over a part of the access gate.
