The cargo box of the electric transportation vehicle driven by a rechargeable battery and an electric motor connected to the battery comprises: a floor frame installed in the floor of the cargo box of a vehicle body; a retractile frame coupled to the rear end of the floor frame to be slid into the floor frame such that the longitudinal length can be adjusted, and having locking pin receiving parts formed on one surface to be exposed to the outside of the floor frame; and a rotary frame. The rotary frame comprises: channel frames mounted on both side ends of the retractile frame to be longitudinally rotated having each recessed mounting groove part on the front surface; a first rotation frame to connect the channel frames of both side ends; and locking pins arranged on the channel frames or the first rotation frame to be lifted to be coupled or decoupled from the locking pin receiving parts.</p> |
