PROBLEM TO BE SOLVED: To provide a care lift for the exclusive use of a cared person on a wheelchair who can stand up only if a carer inserts his/her both hands under the cared person's both arms and raises the latter a little. SOLUTION: A wire 2 hanging down via a pulley located at the end of a square arm tube 8 pulls up the cared person. The wire passes through the square arm tube, passes through a short pipe 7 via another pulley, and then through each of plural metal weights. There are provided a hanging ring halfway down the square arm tube and a pedal near its bottom end facing a floor. Each weight located within a long pipe has a valve 6 whose thread end thrust into a hole of the long pipe thrusts into the weight groove to make the weight float up within the long pipe. By rotating each valve, the weight drops down through the long pipe until a metal weight stopper stops it. The metal weight stopper pulls down two wire ropes by the distance corresponding to the weight applied and pulls up the cared person and the pedal connected with these ropes.
