[0021]

As described above, the moving lift for nursing care of the present invention enables the caregiver to move between the bed and wheelchair of a severely handicapped person and the upper and lower body of the physically handicapped person during transfer between beds. The caregiver's labor can be reduced because the caregiver can be divided into steps for sequentially holding.

Further, in order to ensure stability in the conventional suspension lift for suspending a physically handicapped person from a high position above the head of the physically handicapped person, the width of the U-shaped base is widened, that is, both left and right sides. It was necessary to increase the distance between the members that form the structure, which made it difficult to move in a narrow passage in a small-scale facility. However, in the nursing care lift of the present invention, the position where the weight of a physically handicapped person acts is low. The width of the base can be reduced without impairing stability, and it can be used in a small-scale facility with a narrow moving passage.
