Claim 8:
9. 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 at least one pair of rotational shafts (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); and
wherein a second coupler (228) configured to absorb a deviation angle at which the pair of rotational shafts (226-2, 226-3) deviate from an axial direction while absorbing eccentricity of the pair of rotational shafts (226-2, 226-3) in a lateral direction perpendicular to the axial direction is connected between the pair of rotational shafts (226-2, 226-3).
