Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an elevator capable of elevating members keeping parallelism without increasing size or weight of the elevator. SOLUTION: This elevator is provided with a support part to support members disposed on it, and a fixing part positioned under the support part. The support part is connected to the fixing part by at least four screw shafts which are supported by either of the support part and the fixing part on one end side to be freely rotatable, and engaged with screw holes formed passing through in the other of the fixing part and the support part on the other end side. Between the support part and the fixing part, sprockets are fixed to all the screw shafts to synchronously rotate with the screw shaft, and an endless belt having engagement parts to be engaged with teeth on the sprockets is wound around all the sprockets. A prescribed screw shaft is rotated by a detachable handle. COPYRIGHT: (C)2004,JPO
