Abstract

PURPOSE: To miniaturize a hydraulic cylinder and enhance its strength by forming the inside of an annular wall portion or its outside to be thinner than a welded portion.
CONSTITUTION: A cylinder bottom 1B is provided with an annular wall portion 1C, the inside of which or the outside thereof is bored to form a thin portion 1E thinner than a welded portion A. Thereby, in supplying hydraulic oil, the annular wall portion 1C together with a cylinder tube tends to bend, so that a concentrated stress generated in the welded portion A may be decrease, a hydraulic cylinder may be miniaturized and its strength may be enhanced.
