The gland packing 4 is accommodated in the wide mouth part 3 in front of the step part 2, and a neck bushing 8 with a flange is placed inside the cylinder tube 1 behind the step part 2 to engage the flange part 9 with the step part 2. In the case where the neck bushing 8 is fitted in the flange 9, a radial narrow groove 11 is formed in the front surface 10 of the flange 9, and a pore 13 passing through the flange 9 is formed in the narrow groove 11. Features a hydraulic cylinder.
