PROBLEM TO BE SOLVED: To simply and strongly assemble a link support pin in respect to a rod cover while utilizing the rod cover as a common item. SOLUTION: A piston 6 is housed in a cylinder tube 1, while a piston rod 7 penetrates into a guide hole 8 of a rod cover 4. A clamper 11 is oscillatably attached to an upper end of the piston rod 7, while an upper end of a link 13 is supported to its intermediate portion. A vertically penetrating through-hole 14 is formed on the rod cover 4, into which a support pin 15 supporting the lower end of the link 13 is inserted from a lower side of the rod cover 4. An escape preventive extension part 17 is formed on the lower end of the support pin 15, and sandwiched between the cylinder tube 1 and the rod cover 4.
