Abstract

A telescopic cylinder characterized in that: a plurality of movable cylinders with sequentially increasing diameters are externally mounted coaxially on the fixed shaft of a basic piston part; the piston part going through the above fixed shaft is sequentially and adjacently connected on the end portions on the same side of the movable cylinders, oil chambers with an identical cross sectional area are separately formed between the basic piston part of the fixed shaft and the innermost movable piston, and between piston parts adjacent to each other in the axial direction; a passage interconnecting the oil chambers is installed and one of the oil chambers is connected to a supply line of an operating oil.
