To enable implementation of conveyance and transfer in different spaces by holding a human body so that a posture of the human body is not changed in transfer and by reducing influence on the human body to the minimum in the transfer.SOLUTION: A seated posture fixing transfer nursing robot is provided, the transfer nursing robot including a base, a whole standing mechanism, a lifting mechanism, a foot mounting thigh lifting mechanism, a lumbar part supporting and protecting device, and a stretchable cushioning mechanism. The base and the whole standing mechanism are movably connected via the lifting mechanism. The foot mounting thigh lifting mechanism is provided as a foot mounting plate vertically movable in a longitudinal gap of an external cylinder of the base. The lumbar part supporting and protecting device is provided above the whole standing mechanism and is forwardly and backwardly stretchable in a horizontal direction. The stretchable cushioning mechanism is fitted into a lower end of an internal cylinder of the whole standing mechanism, is capable of moving upward and downward in the vertical direction together with the whole standing mechanism, and is forwardly and backwardly stretchable in the horizontal direction.SELECTED DRAWING: Figure 1
