Claim 9:
10. The payload transportation device of claim 1, wherein the lift-driving portion comprises a lift-driving unit (210) configured to generate a rotational force to vertically lift the loading plate,
wherein rotational shafts (226-1, 226-2, 226-3) configured to transmit the rotational force of the lift-driving unit (210) to the components included in the lift-driving portion (200) provided in the second assembly (2) are provided in the first assembly (1),
wherein a decelerator (223) configured to reduce a rotational speed transmitted from the rotational shafts (226-1, 226-2, 226-3) is provided in the second assembly (2), and
wherein the rotational shafts (226-1, 226-2, 226-3) are connected to a slide groove (223a) of the decelerator (2230) to transmit the rotational force while sliding in an axial direction.
