Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a lifting device with a simple configuration that can be easily moved vertically in a stepless manner.SOLUTION: The lifting device has lifting bases 4, a mounting base 2 and two pairs of link mechanisms 6a-6d whose ends are loosely fitted to the bases respectively to be movable horizontally. The two pairs of link mechanisms 6a-6d are configured to form pantograph structures 5 crossing each other via joints 14a and to allow distance between the lifting bases 4 and the mounting base 2 to be changed. The mounting base 2 comprises a rotating member 10 whose surface is threaded and a horizontal movement member 11 that is screwed in the rotating member 10 and hanged on one ends of the two pairs of link mechanisms 6a-6d so as to convert rotation of the rotating member 10 to horizontal movement.
