PURPOSE:To allow collection of leakage by providing a cylinder with leakage receivers and connecting the leakage receivers through a leakage reservoir to an absorber. CONSTITUTION:Leakage receiver 25, 26 are provided at sliding portions between cylinder heads 19, 20 and piston rods 23, 24. The leakage receivers 25, 26 are connected through a leakage reservoir 29 to an absorber 30. Thus constructed, when there is any leakage, the leakage is immediately absorbed from the absorber 30 in a main flow of pressure liquid, permitting continuation of operation in the leaking condition. Therefore, the number of repairment and maintenance can be reduced, increasing operating efficiency.
