PROBLEM TO BE SOLVED: To provide a liquid pressure spring which encloses a compressive liquid at a desired pressure inside a cylinder, and to prevent pressurized liquid from leaking from the inside to the outside of the cylinder at the time of regular operation and percussion without using a check valve causing an inner pressure drop. SOLUTION: A liquid pressure spring 1 comprises: a cylinder 2; a blocking means 4 blocking one opening end of the cylinder 2; a blocking means 6 blocking the other opening end of the cylinder 2; a compressive liquid 8 which is enclosed in the inside 7 of the cylinder 2, and pressurized at a predetermined pressure; a rod 9 which generates a pressure rise in the liquid 8 of the inside 7 of the cylinder 2 by penetrating through the inside 7 of the cylinder 2; and a piston 11 which is arranged in the inside 7 of the cylinder 2, and attached to one end 10 of the rod 9.
