Claim 4:
5. The payload transportation device of claim 4, wherein the deceleration portion (220) comprises:
a first decelerator (221) connected to a motor shaft of the lifting motor and configured to transmit rotation of the lifting motor to rotational shafts (226-1, 226-2, 226-3) which meet the motor shaft at a right angle;
a second decelerator (222) connected to one end of the rotational shafts (226-1, 226-2, 226-3) and configured to transmit rotations of the rotational shafts (226-1, 226-2, 226-3) to rotational shafts (231-1, 231-2) of the first power transmission portion (230), which meet the rotational shafts (226-1, 226-2, 226-3) at a right angle; and
a third decelerator (223) connected to the other end of the rotational shafts (226-1, 226-2, 226-3) and configured to transmit the rotations of the rotational shafts (226-1, 226-2, 226-3) to rotational shafts (251-1, 251-2) which meet the rotational shafts (226-1, 226-2, 226-3) at a right angle and are provided, to be parallel, at positions facing the rotational shafts (231-1, 231-2).
