The body of cylinder(10) consists of three divided cylinder block(10c) having the actuating fluid room(14) attached the adapter(12c) which connected with the one and the two divided cylinder block(10a, 10b), the piston rod(12b), and the piston(12a). The girth of these are assembled with the bolts, so that the actuating fluid room is sealed by the first and the second preventing packing for oil leaking(18, 20). The circle projection(36) placed on the flange(22) of the first preventing packing for oil leaking(18) is fixed between the second and the third divided cylinder block(10b, 10c). The hold of the second preventing packing for oil leaking(20) is placed between the piston and the adapter. The circle folds of the packing(20) are contacted with the circle projection means(34). The circle projection(38) of the second packing(20) is fixed on the first and the third divided cylinder block(10a, 10c), so the actuating fluid room(14) is sealed. The operation of the piston assembly(12) is continued in the body of cylinder(10) although there is the crack. Cause the actuating fluid room(14) is isolated.
